the exhaust for the SS's are the same and will bolt up. the difference is the piping size. they are mostly offered in 2.5" compared to 2.25"

was talking to my father in law who is a mechanic of 25yrs and says that you gotta be careful when playin with the catalytic converter. when you go in and install a tsudo or whatever, do you leave the stock c.c or install a diff one? sry...ima noob! haha...

i mentioned to him what IMADREAMER said on pg 1 about getting a good muffler and putting money into headers and he agreed with that more then messing with the whole exhaust system. He knows a lot but more about BMW's and older cars..."not in the loop with all this new $hit," as he said...

...and im leaning towards building my cobalt for show more then the strip, but want to have some of the same highlights...nice sounding exhaust, fast-ish, and look great...

-thanks!

u leave the stock c.c on unless your planning on putting a test pipe on or a long header that gets rid of the c.c or if your going wiht a mangaflow highflow cat.

Cat-Back exhaust systems attach behind the cat. The stock Cat is left alone.

If you look at exhaust systems logically it just makes sense. If you free up restriction at the back it does little to no good because you still have restriction at the front of the system. For the same price of a cat back you can get a header and dp which will alter the sound and actually make horsepower. IMO it's silly to go changing cat backs when they are just noise makers and add no real horsepower. But that's just me, to each their own.

this is true but however when you have a 2.2 that stock exhaust just looks so ugly haha and i only paid 178 for my catback system... not sure were i can get a header and dp for 178 bucks?

i'm probably going to be looking at a shorty header dp at probably a 2.5" after i get this catback on.

and unless your one of the guys with an SS, it makes sense to change the whole exhaust. the stock muffler sucks and is very heavy and restrictive. and the stock piping is a joke. its small. so while doing a header/DP combo first is prob better it is still important to upgrade the rest of your exhaust including your cat

i'll be going to either a magnaflow high flow cat or a test pipe don't think they make a test pipe for the cobalt to my knowledge so i may just have to see if i can find one that is right length with the same flanges and see if i can make it work.
