ok so I am looking for a cat-back exhaust in the near future for my ss/sc but i don't really want anything that will overpower the supercharger sound. sound clips do not really show exactly how different exhausts sound in real life. can someone please guide me in the right direction? I would prefer to not have to spend very much because I am a student and I just bought an injen cai and stage 2. What do yall think about the megan, dc sports, and pacesetter. Also would a custom exhaust be a good route?

Thanks

Custom can be good.....if the guy is skilled at bending pipes (and has mandrel bending tools). Otherwise, I have a Magnaflow stainless steel catback and the build quality is top notch. Perfect fit, and it's not too loud (it has a free flow resonator and muffler). I'd recommend Magnaflow for sure.

goo custom thats what i did and i dont regret it

Go with a header/downpipe combo...that is where the most restriction is in the exhaust anyways. I got the ZZP header/Downpipe combo and it sounds good with the stock catback.

RedEcotecSS

sounds good with the GM performance catback too.

GMPP Sport.... exactly what you want. At RPMs up to 4000 you hear the exhaust sounding very nice and clearly and after that you hear the supercharger/cold air intake screaming in competition..

I have a good video of this I'll post when I get home from work..I have a stage 2 and k&N cai and gmpp catback

wouldn't there still be a big restriction because the extra flow it frees up would still be going through the stock cat-back?

Well I have a base model and the CAI Mod and I can hear my mod over my exhaust easily without it sounding stock, here is a vid of my Tsudo cat back with the ss/sc header (best with subs or a good set of components, from the back so you cant hear the CAI Mod.):

And here is a really old vid of the same cat back with a stock 2.2 header:
If you have a good sounding system hooked up to your computer you should be able to tell that the first vid is much deeper at idle all the way up through 4k. There is little drone on the highway(just drove 4 hours yesterday, trust me on that, I kept the music off so I could hear the exhaust).

lets just say once u break in the megan n1 exhaust with custom piping and a high flow cat u will save lots of $$$$ and wont regret it. the first weak you get it its loud and stinks then it burns all that **** off in the inside and sounds awesome and performs very well

Megan N1 and Tsudo N1 are the same eccept for the price, tsudo can be found for 250 shipped.

Its kinda hard to explain what sounds good. What sounds good to some people might sound like crap to you, vise-versa.

SLP, and GMPP have a nice sound to it. Vibrant isn't too bad either.

Or like they said, go custom

I have the GMPP Touring.


Mmmmmmmmmmmm.

So deep, and when you get on it opens up quite nicely.

I have a CA V1 header and a 2.5" catted DP as well.

At first it was hella quiet, not much louder than stock...I have had it for close to two years now...and it sounds awesome.

if i decide to go with a custom exhaust what size tubing would everyone recomend? Also what would the differences be if i went with 3" tubing as opposed to 2.5" tubing?

Go with 2.5 unless you plan on putting in some extremely high boost numbers...

Unless you plan on swapping a turbo in then dont go over 2.5, the SC can only handle so much and from what I understand torque dies with bigger exhausts.

I just bought this SS that has a Megan at back on it. It is too loud for me and I'll probably take it off and install a Magnaflow at cat back. I'll make someone a good deal on it. Bob

IMO the GMPP touring and Hahn exhaust sound the best on the Cobalt SS/sc... There is a clip on youtube of a guys with the hahn exhaust.... its orgasmic.

yea megan is really loud with the zzp header and downpipe combo i be pissed when i installed my s/c kit and cant hear the whine

SuperSlow420

Stick w Stock piping 2.5in. otherwise to big of a whole will cause a lot of back pressure and will lose whp and torque!
