So my exhaust is gunna be gone soon. (rusted through) Although, its still not making noise, but it is nasty under there.
What do you guys recommend me getting ?

 

Greddy SP2.

 

thats for the muffler, correct ?
what about those b pipes, y pipes and cat ?

 

dont mean to jack the thread but im looking into replacing the exhaust as well... cat back.... its all rusted through anyways... i already have a y-pipe and just want it to sound al little louder... i hate stupid fart cans.. i actually want it to sound as close to the gran prix as possible....

 

sorry your post was asking about a muffler, the greddy sp2 is a fullt cat back system. Excellent sound.

For muffler I'm not too sure but have heard good things (reviews and sound clips) of flowmaster mufflers. Which type I dont know but you'll need a shop to weld it on. For Bolt on you have two options and both are pretty expensive for just a muffler.

How does that look? Would you do it ? Or buy different brands for each(y-pipe, b pipe, etc.)

 

Greddy SP2....cat-back....if u can find an Apexi WS (good luck) that would be first choice

 

im assuming u mean the pontiac grand prix gxp, that car has the SLP ENGINEERING "loud mouth" cat back system. not sure if you can get just the muffler, been a while since i sold my GP, but they may be available.

 

So this is what I put together so far.
Greddy SP2 cat back
Budget Y-pipe
all I need now is a Catalytic Converter, correct ?

 

Its all good
Is your Cat rusted out too?
If so youll need a high flow cat, you can pick one up from Budget Exhuast (Lssexhaust.com) and that is it
If you cat is fine the you won't need a cat

 

If I use the stock cat would that affect anything, that everything will be aftermarket exhaust pretty much ?

 

Have fun getting the bolts disconnected from the cat...

 

Thanks for the heads up, but that doesnt even closely answer my question.
