I love mine - the sound is loud when you get on it, but very quiet and subdued on the highway. It has a nice low tone to it - not rice at all. A couple of my friends commented on it (in a positive way). If you want to go louder sometimes, get an electric cutout after the turbo.

Only real problem I have with it is since my car is lowered with Sportlines. The exhaust now rests on the rear axle and makes a terrible buzzing sound all the time.. Its bugging the crap out of me. You cant raise the exhaust any higher, or the tip touches the bumper (which would eventually melt). I'm seriously considering taking my torch to it, heating the crap out of it, and pounding it until it doesn't touch anymore.

Good quality product. Just to expensive for not much sound or performance gains.

worth every penny imho

I am usually the one to go against hahn for there rediculously high prices, but this is exhaust was well worth it... It makes the car sound better than a cobalt should, it is deep, loud when you get on it, quiet when your not driving agressive, and the sounds it makes when you down shift

I actually just put mine on. I would have to say it is very quiet... but i also believe it has to break in some. I also got the Hahn Catcon Downpipe..... Which is taking forever, almost 3 weeks here. do the combo... you will be very glad

hmmm...I recently had one installed with H&R lowering springs and have not encountered any metal/metal contact...might want to readjust your connectors then tack weld them in place so they don't move...

The Hahn is extremely quiet...just margenally louder than stock...even at WOT...I'm seriously contemplating getting the matching DP...

It is very high quality...even my exhaust guys (high end custom header fabricators) commented on how impressed they were with the fit and finish...

I'm going to buy one just because the stock muffler looks like ASS! I cant stand the cheap looking lunch pail hanging down below the rear valence.
