3" downpipe???
 

Ok...i just got a 04 SS S/C and the first thing im gunna do is the wizaired kit...but after that i was gunna look into exhaust...i like the stock sound and dont want it much louder...i just want more flow... Would just the 3" downpipe change the sound and make it crappy?? whats the best option for me?? any help is appreciated!

nothing is really going to change the sound (wizaired will make the WOT louder) until you get into your resonator / mufflers

3" DP w/ a cat delete will make it a super super tiny bit louder, with a slightly different tone.

Thats the way I had my old 99 gtp setup- I did the 3" catless DP, then I wanted it a hair louder and took the resonator off- and it ended up exactly like I wanted it.

i was thinkin the 3" downpipe with hiflo cat and leaving the res adn stock mufflers...any other opinions? i dont want it loud...i want the low rumble like it is stock...just want more flow

i like the sound of this...http://www.youtube.com/watch?v=sPt_ZgWRi6c but i dont ness. need it that loud...i just like the tone and how it doesnt sound crappy in the upper rpms...

With a high flow cat, you will only very very slightly change the sound from stock. I'd say if you like the stock sound- then thats just about where you'll be after.

Put my 3 inch catless downpipe on today, I really cant hear much difference at idle. Little raspier when you rev it, but not much.
Not s/c yet, but can feel the difference.

If you want to increase flow while not making it louder then put the powerlog and downpipe in, the change in sound is barely noticeable, you'll be more impressed with the power than the sound change, but this will greatly help flow, and lower KR if you're S/C.

I agree.

After the CAI, do headers or Powerlog + Downpipe

I say don't waste your time with just a downpipe, especially if you can get a set of headers that bolt right up. That was my problem - nobody makes headers for my model Monte, I'd have to modify the firewall and I just don't feel comfortable doing that.

Besides, there are headers available for less than $400 - and if you get a Plog, ported rear, and downpipe, that's running about $300 right there.
