A lot of full exhaust systems come with silencers so that would be my advice to you. It doesn't make it softer too much, but definitely some decibels lower than without it.

well if your looking just for sound u could always just do the muffler delete. wouldnt cost you much at all and sounds pretty damn good, better than many full systems actually.

I wouldnt do a muffler delete on a 2.2 or 2.4 cobalt. They only sound good on the SS/TC. However you could do a resonator delete. It makes it a bit louder, but also a little bit raspier. There is a video on youtube showing one and I didnt think it sounded that bad. Either that or you can swap your OEM muffler with a higher flowing Magnaflow or Borla like many others on here have done.

Speaking of, does anyone know where I can get the nuts and bolts to the silencer for the Tsudo exhaust. I have the actual silencer I just lost the bolts... long story lol

Anyways, I didnt think it warranted a whole new thread just wondering if anyone could help.

I was going to try that I was just wondering if anyone knew where I could get ones exactly the same and I don't remember exactly what they were. Once I do get them I'll be sure to use loctite this time around...

I believe the Tsudo exhaust (if you're on a budget) is similar to the GMPP Sport edition (if you have cash to spend) that I have and it is not very loud at all. I've never had a problem with police and one compliment I do get is that it sounds great without it being obscenely loud. It has a nice low rumble that I can barely hear from in my house at idol, and as for driving it's only loud when you put your foot down. I also have an intake, which makes the car louder.

actually they sound a lot less raspy on a 2.2 or 2.4. most systems ive heard, namely the vibrant and magnaflow ones r FAR raspier. but obviously ur gonna get an extra, maybe 5 hp from it. not worth it to me for 500+ bucks though.
