why? stock pipes are fine. 3 inch cat backs you loose hp. unless you got a turbo.

i feel your pain dude,,,,,,buy replacement pipe off ebay. the Y pipe is like 80 bucks shipped. its all you need, other then a new res, or glass pack if your gonna reuse your mufflers.

whole stock cat backs are like 270 ish shipped off ebay, im running one myself.

Yup!

I like a lil rumble but certain rpm's it sounds terrible. I have magnaflows right now. But i'm going back to a stock system on my next gtp that i'm building.

So should I get a y pipe and resonator?

yes sir. or a glass pack is much cheaper. does the same thing. i was running one on my old cat back.

Or you know...

Go watch videos on the internet, since it exists...

And find what fits your ears the best.

I'd tell you to go with a 3" catless downpipe, whatever resonator, and new 2.5" piping to some quiet mufflers. Nothing chambered. So no SLP, Flowmaster, Jones Super V, etc.

Think Borla, Corsa, Magnaflow, GMPP.

There. That's it. The rest is up to you brand wise.

 

[Jason97GrandprixGT]

Would a dynomax y pipe and Jones 2 inch glass pack do?

it should, but iirc the pipe is 2.25 so you might need an adapter to make that res fit the pipe.

Thanks ppl I recently put a 02 Buick Regal engine in my car and it runs like a champ. I'm doing the tune up today for it

3" catless DP, delete "U-bend", 2.5" back. I pulled the resonator and I'm running magnaflows on mine and I like it. But it's personal preference. But what they say is true, the 3800s don't sound super awesome with different exhausts, but if you want more tone and sound you will get drone like a mother f*^ker...

Drone..... These aftermarket 'performance' systems should come with a free bottle of Tylenol for the drone. Oh holy hell. My friend ran SLP and the drone would give me a headache after 10 minutes. Terrible. Car sounded like crap. Exhaust will never sound good on these cars. Just annoying. I personally replaced mine with a Walker, aka Dynomax, stock replacement cat back. I agree with no chambered mufflers. If anything make sure to run a resonator and fiberglass packed muffler.

Is there an aftermarket/mandrel bent exhaust that is quieter than stock?

[Scottydoggs]

if you use stock ish mufflers and a res it can still be quiet with mandrel bends. theres a 2.5 option listed on that web site.
