I'm looking to just pick up a muffler for my 07 Cobalt SS/SC 2.0L. I'm not looking for any HP gain really as its an everyday car, i just want a deeper little louder sound if you know what i mean.

I was looking at some magnaflow ones, but what should i be looking at? The round body or oval bodies? What inlet/outlet size etc..

Also sort of a stupid question, but i'll never know unless i ask (new at all this) do resonators come with mufflers or whats the deal, because i've heard that i should have one to keep it the sound down a bit..

Any info would be great, thanks a million guys!

 

Here is my custom Magnaflow catback. It includes part numbers and everything so it will save you some time. I tried searching before for what offsets and whatnot to use and couldn't find a deff answer.

Thanks for the post. Just looking for some opinions on what to get for mufflers, not looking into a full system. Any help is greatly appreciated!!

 

That was just mufflers.

 

do you get any rattles

 

Like the exhaust hitting something? No.

 

Get a magnaflow muffler dude. It'll sound real nice.
