ZZP exhaust or ?????

[Eagle]

So... the GTP I just picked up the exhaust is completely trashed and needs replacing.

http://www.zzperformance.com/grand_prix/products1.php?id=801&catid=110

This is what I'm thinking about getting in the 3" flavor. The car already has a 3" hi perf cat and piping, so I just need the cat back system.

I don't mind SOME volume, but I don't want it loud or droning.

ZZP claims their setup makes quite a bit more power than stock... so not sure I want to just slap some stock stuff back under there.

Help please?

A stock catback will support 300 WHP. I havent heard one, but everyone that has them says they are the cats ass.

I like hooker maxflow mufflers myself.

I'm happy as hell with my stock catback

 

[The Broken Regal]

yikes, dont bother with that, especially with aluminized for a winter/beater/DD lol

then you step up to SS and you are talking 600

just get another stock catback or buy a used system off clubgp or something like that

you can have an exhaust shop make a custom setup for cheaper with the mufflers you want though iirc

 

[Eagle]

clubgp... ya.... looks like its time to setup an account there!

 

[The Broken Regal]

it can be a crapshoot and i would only buy from people who are regulars or i have bought from before but you can find some good deals on used stuff

other than here, there, maybe some junkyards, not many other places that i can think of for cheap used parts

 

[Eagle]

Yea, used parts suck to find quality parts. That's why it almost seems easier to get the ZZP setup

A guy from McHenry is looking to unload his stock exhaust. He bought the dynomax one off the parts car. Don't think he has swapped them out yet tho. http://www.grandprixforums.net/f49/get-this-stuff-out-my-garage-20109.html

There is a GMPP catback for sale on CGP now. I like how it sounds. Love the tips as well. $250 IIRC.

Damnit. I registered @ CGP, but now it won't let me login... says something about [Administrator Approval Required.]

Gues I'll have to wait for the admin to wake up before I can post to that dude's FS thread. $250 + shipping seems like a decent deal... sure beats $567 :eek4:

Get the used GMPP. That's what I have on mine. Before that system I had an aluminized system fabricated by an exhaust shop. It rusted through in less than two years. The GMPP may have some surface rust because it's the lesser stainless, but it won't rust through. It uses magnaflow mufflers.

Stock ftw..... Minus that huge ass resonator.

I gotta see what happens with the GMPP setup, but if that falls through I'll look harder for a stock catback...

 

[PANDA]

stock catback.

If you want to put money into the car a few hundred would be better spent for some headers.

If you can get the GMPP setup that would work nicely for your current mods.

As for the stock catback...it has what is typically called u-bend restriction (area behind the cat where the pipe is collapsed alittle to allow the rear o2 to be protected.) that should be replaced.

I don't know that I'd recommend a stock cat back unless it was super cheap...but I would recommend stock mufflers with a good resonator and mendrel piping and better y-pipe before them.

 

[Bob Kazamakis]

That's in the downpipe isn't it? It's been a while though....

 

[DanJ]

I believe if you upgrade the downpipe it replaces the Ubend, but the Ubend can be replaced on its own.

Sounds like his car already has an aftermarket cat, so there's likely a downpipe already on it.

 

[Bob Kazamakis]

That's what I thought. Ubend is on dp side of the flange. I bet if it has a highflow cat and aftermarket exhaust it probably doesn't have a ubend
