96 Z28 Exhaust help!

[96smokinZ]

going to do an exhaust upgrade over winter. i want the bitch to be heard and sound mean. not cackly, just the nice muscle sound. i was thinking headers and some good loud flowmasters. anyone know of a good set up for the LT1???

[NapalmKornFlakes]

Don't get flowmaster if you don't like the cackle. Thats what they are know for. LOL

i like those flowmasters

[96smokinZ]

well a little is ok. flowmasters are on alot of muscle cars and sound good. and your you tube vid dont show up. i have manifolds on her now and a hooker aerochamber cat back but its not loud enough. it purrs nice but kinda has more of a v6 sound. i dont like it

[96smokinZ]

ok got the you tube.

[OneFastZ]

I have an 02 Z28 with no mufflers but on a LT1 from what ive heard you get the most power with MagnaFlow check on ls1tech.com most LT guys are runnin it

[96smokinZ]

ok ill do some research. thanks!

[Sohcgt96]

Just don't try and do a hack-job dual setup!

I used to crack up every time I'd read a new guy on the f-body forums absolutely *insist* that they need *true duals* because... well, just because they do! But a proper single system will not only perform as well or better up until the 5-600 HP range but actually work the same was as an X-pipe.

[pddye]

On my 96 I took the cats out and ran a borla catback. I thought it sounded really nice. On my borla I also had an electric cutout and if you know how the borla system works it was a nice setup. If it was me I'd just buy a mac off road y-pipe, sell the cats off for the same price you buy the mac for and see how it sounds with your hooker exhaust and go from there.

[96smokinZ]

i take it that y pipe is a bit longer or will i need an extension pipe? how much does that cost? will that be ok with manifolds or shall I put some headers on?

[96smokinZ]

and no hack jobs. thats not how I roll son lol. cat-back is fine, i just want something mean.

[NapalmKornFlakes]

and no hack jobs. thats not how I roll son lol. cat-back is fine, i just want something mean.

Single 3" all the way back with a bullit muffler. :right:

[96smokinZ]

bullit? never heard of that one. anywhere i can get a sound clip?

[pddye]

I thought they were a lot cheaper then that, around $90 or so. When I did mine I just cut the cats off and i'm sure if you could get your original y-pipe off you could take it down to Ryan an Meineke and he could take the drivers cat off and put a flange on with a little pipe and then cut the passengers off. Or you could just go out and buy pacesetter headers with their off road y - pipe and go all the way. I guess it depends on how much you want to spend.

[pddye]

I heard the slp loudmouth bullets sound terrible. A guy from princeville had it on his car.

[96smokinZ]

that SLP isnt bad. how loud is it?

[pddye]

http://www.harrisspeedworks.com/shop/product.php?productid=16649&cat=364&page=1

Now if you want a good bang for your buck you'll just step up to this which I run on my car.

[NapalmKornFlakes]

that SLP isnt bad. how loud is it?

There is a reason that muffler is in the Loud Mouth family. LOL
Guy I worked with had duals and those on his 95 Camaro and it was loud. Especially when he got into it hard.

[pddye]

http://www.pcmforless.com/index.php?option=content&task=view&id=44&Itemid=40

and then get a base program to adjust for the kit from these guys. haha

[pddye]

if you want loud just put in a cutout. I run a hooker catback with a cutout.

[96smokinZ]

yeah i am liking your SLP idea. guy messaged me about a magnaflow cat-back also. might check that out. oh and i already have a nitrous works wet kit on my car

[pddye]

good deal. Usually people are scared of it. How big of a shot are you running?

[96smokinZ]

well the car came with nitrous. i dont know much about it. thats why i wanted a nitrous pro to look at my car sometime. i know cars pretty well but nitrous is new to me. it is a 50-100 shot i believe. nothin too crazy

[pddye]

Even the smaller solenoids can handle up to a 200 shot. When you bought the car did they say anything about getting it tuned for nitrous knocking the timing back some?

[96smokinZ]

no. the guy i got it from didnt use it either. he said he only purged it a couple times. he didnt know anything about it either. the guy before him was a mechanic and put it on. other than that i know nothing. i havent checked timing, i know its gotta be off by a little bit.

[pddye]

The lt1's are a pain in the ass to program thats why I used pcm for less. They did a really good job tuning my comp cam 503 cam and nitrous. Never had a bit of trouble after it was tuned. I'm sure the tune was conservative, but for the price I'd rather it be conservative then aggressive since it is a mail order service. I'll tell you one thing tho that when you finally do use that nitrous system you'll be filling the bottle all the time. haha

[96smokinZ]

yeah id like to try it at least once since its new to me but i dont want to mess anything up. thats why i want someone who knows it to check it out. im sure the guy wouldnt throw nitrous on it without upgrading stuff to support it, but you never know.

[pddye]

if your really only running a 50 - 75 shot you can just run it as is. When I upgraded the cam and went to the 125 shot thats when I put a bigger pump in. Which those really don't cost much either.

[96smokinZ]

does the timing have to be retarded for that small of shot as well or no? do you know alot about nitrous? id like to get a good set of eyeballs on my car to tell me about it.

[pddye]

It is my opinion anything at 75 or lower you don't have to retard the timing. And since you can only run a wet shot you won't have to worry about injectors or anything like that. Also a stock fuel pump is more than enough to run a stock motor with a 75 shot as long as the pump is in good mechanical condition.

[96smokinZ]

ok. should be fine in that department. also i dont know how to use it per say lol. i was told the bottle had to be somewhere in 900-1100 lb range to run. also has bottle warmer and purge kit. what temp does it need to be at? its all british to me. all i know is turn bottle on, hit full throttle, hit go. dont know when to turn solenoids on or nothing or however it works.

[pddye]

I've never liked the type of system where you have a momentary switch to activate the kit. I've always like the micro switches engaged by the throttle cable but that is just me. Your right on the bottle pressure and the heater will do its thing because they have a built in thermostat. My harris bottle has a gauge but if you don't just buy a gauge that goes in line between the bottle and the line. I used to have a purge kit but sold it off since they are just flash since I just crack the line before I get in the staging lanes.

Just make sure you have the right plugs to the right gap. post number 7.

http://www.ls1tech.com/forums/showthread.php?t=846230

And do what ever you feel comfortable with. I've always started out with a small shot and just go by feel.

[96smokinZ]

so whats sequence? turn bottle on, let warm up if its cold, turn main switch on, then push button at full throttle? it has switches on the throttle that will only let it work at full throttle too.

[pddye]

Just turn the bottle to open. Then you have an activation toggle switch which you will flip that to on when the car is running. That will bring power to the relay. Then your full throttle activation switch will complete the circuit for your relay on full throttle sending power to your solenoids opening them up on full throttle. You shouldn't physically have to turn any other switch on besides the arming switch.

[96smokinZ]

given that the bottle pressure is in zone? if not let the warmer do its thing? i read that link you posted. so with those switches on the throttle how safe is that? what are the possibilities of it taking off before i hit sixth gear??

[pddye]

You never want to use nitrous in 6th gear. I think its only really safe about 3000 rpm to your rev limiter that is around 6200 on that car. On my 96 I used to shift around 6800. If you have what I think you have which is a throttle micro switch its impossible for it to engage until you are at full throttle since its a really simple design. Its hard for me to say what you really have for sure because the person who installed it might have put different parts on it then the base kit should have came with.

[96smokinZ]

it does have those switches. i saw them by the throttle. allowing them to trigger at full throttle only. so with those, will it spray just the entire time i have full throttle or is there a limiter somehow? yeah i dont know what parts are regular or different. thats why i wanna get eyes on it.

[96smokinZ]

well THE switch. didnt mean to make it plural

[pddye]

So with the switch by the throttle it will only engage on full throttle only after you turn your toggle switch on the inside to the "on" position. A good way to check to see if you solinoids are turning on is take the lines off the solenoids and with the motor off flip the switch and then with your hand move the throttle to full throttle next to the throttle body and listen to if the solenoids click on and off.

[pddye]

Its a really simple thing so there is no limiter besides your arming switch and the jets you put in the nozzle unless you want to get a window switch and make it only turn on during certain rpms. Their are also other fancy safety switches which i've never really cared to use.

[96smokinZ]

ok. im with ya so far. so how does that switch work exactly? since it only triggers at full throttle, it could be set off in early gears correct? does that mean flip the main switch inside when i hit 5th or what?

[pddye]

If your still full throttle in 5th you'll be around the 130mph mark so you won't have to worry about it. I wouldn't spray nitrous any longer then 14 seconds straight. Basically the micro switch (full throttle switch) is just a little arm that gets pushed back from the throttle arm. So when ever you are full throttle the arm gets pushed back and if your relay has power then it will turn the solenoids open. Think of the relay as an automatic switch. When you bring low current voltage in the one side it engages the switch to turn your larger wire on. Their are tricks to make the nitrous disarm in certain gears but it requires other switches in your shifter so they go on in some gears and off in others. Its kinda a pain in the ass but it works.

[96smokinZ]

so you are saying that i shouldnt turn the main switch on until im just before full throttle in 5th? and i have no control over the spray length outside of just letting off the gas right, or if i shut the switch off? if im running a quarter mile it wont be a long run anyway

[pddye]

No turn the switch on when you are stopped. Race the guy next to you, then usually the race is over in forth and on decel you won't be full throttle so usually when I think about it I will shut the system off. You'll never use the system in 5th or 6th or you'll be using it to long and could have some serious problems since its just spraying and spraying forever.

[pddye]

When I said you won't have to worry about it I ment you won't ever be using your nitrous system in 5th or 6th so you won't have to worry about 5th or 6th

[96smokinZ]

ok. i got ya. now can the switch be triggered at full throttle in 1st through 4th? or how does that work? since you turn it on when stopped.

[Nanner]

just chiming in... i have a magnaflow catback, American racing 1 3/4 headers, 3 inch off road Y pipe: this is how it sounds...

8PYIcrJO_J0

just for reference and all..

[96smokinZ]

cool. thanks. btw i like the bird man....saw ya at lennys

[pddye]

You just turn it on. I guess I can't explain it in writing like i'm trying to. If I ever see ya out and about it would probably be easier to show ya in person.

[96smokinZ]

ok sounds good. dont know where i would see ya tho lol

[pddye]

I'll be at vicary day for sure if your going

[96smokinZ]

what and where is that??

[pddye]

It's october 19th. Eric Vicary rents the track up at cordova on that sunday. Just head up to winners circle and get signed up for $40 if your interested. The call out thread is in the kill section.

[96smokinZ]

you gotta pay that much just to watch or is that racing too? i dont plan on runnin

[pddye]

I think its like $6 to watch or around there

[96smokinZ]

ok so do i just show up then? or sign up since its rented?

[Gunters96lt1]

i put long tubes and a ofy-pipe on my car, then had an exhaust shop run exhaust out the back with no muffler. sounds awesome to me.

[pddye]

Spectators just show up and pay at the gate from what has been in the past

[96smokinZ]

ok cool. prolly come check it out. one quick one since you got bird. are the bolt pattern for the wheels the same camaro/firebird?

[pddye]

They are pretty much the exact same car besides a few body panels and interior.

[96smokinZ]

thats what i figured. thanks alot man, for all the knowledge. i feel smarter now lol. hopefully i can see ya at vday. ill bring my car.

[pddye]

I'm still really new at a lot of things about these cars but the more I get into mine the more I figure out about it. One of those things you just can be scared of and if you break something you can always fix it.

[96smokinZ]

yeah. im lookin at a house tho. means....broke ass for car haha

[96smokinZ]

other than that im not worried about screwin up somethin really. toys are made to play with

[pddye]

thats no joke on the house thing. Im almost done with the first phase of the house project which is jacking the house up and putting new blocks underneath with just me and my dad doing it from start to finish. Just a few more feet to go and its time to shell in the back. Gotta love the fixer uppers. Even with the home equity loan it seems like it still takes a lot out of the back pocket.

[96smokinZ]

yeah its my first house, so good for loans. its a newer house. all it needs is updated electrical box and what not so shouldnt be too bad. good luck on finishing

[red93z]

dont get a flowmaster catback like people said earlier in the thread.I had it on my 93 z28 with longtubes,ory and the flowmaster catback.It wasnt loud enough for me and even with simple boltons I could feel the exhaust being choked up a bit.Id say keep your hooker catback,get some headers and get a cutout.If I get this 95 z28 im working with right now thats probably going to be the route I go,unless I go true duals.

[Dewrod]

The last setup I had was a set of LT's, 3" y-pipe, into a Hooker catback. Couldn't go wrong with that setup, nice an deep at idle, then at WOT its nice an loud. :)

[slippinsideways]

long tubes for sure

have ryan help you figgure out a true dual setup with an X
no cats (if you want it that loud) or highflow cats.

flowmasters for open but will have a crackle,
mangnaflows and borla i have heard and dont dislike either.

but run two mufflers, and hide them up by the trans or if ryan can squeese them out back!

[Dewrod]

If you end up going with a TD setup, I've got a set built up already, with an X-pipe, two Flowtech Afterburner mufflers, with turnouts @ 45*. Sounds awesome. Can get a pic if you like.

[Solargalactica]

yeah its my first house, so good for loans. its a newer house. all it needs is updated electrical box and what not so shouldnt be too bad. good luck on finishing

hell if you get everything ran as far as any new wiring you want to do you can find a licensed electrician to come in and wire it all up to code for like $200 which isn't very expensive and u have the peace of mind knowing it was done right :).

[honda450r]

isnt that car sold??????????????????/

[Bdubs]

this thread is old as shit

[slippinsideways]

who the fuck dug this fucking thing up!
damnit i didnt see that
