I know pretty much nothing about exhaust and I am looking to get information on the type to best fit myvehicle. I have a 2007 Cobalt 2.2 LS. I currently have the GMPP intake and I want to get a bold, yet not "screaming" exhaust. I have been looking at the Catback + DP on the ZZP website but don't know if it would work for my car model. Any suggestions?

 

All the exhaust parts out there are interchangeable between all the trim levels. If it works for a 2.0, it will work for a 2.4 and a 2.2.

 

A lot of people have been going with the ZZP Header/DP combo on the stock exhaust. It sounds good, because it is not high pitch, but it is still distinct and aftermarket.

There is actually a Group Buy going on with that combo right now, you could get it for less than $350 if we can get enough people, plus a lot of options. A lot of the info is on the first page. Post up questions if you have them though.

Also, try searching around for what other people have, and try YouTube to get some good sound samples.

 

i had a corsa and really liked it

 

ZZP is also selling the cat-back part of the exhaust as part of the group buy.

 

Yea, sorry I forgot to mention that. Their full 3" catback, 25% off if you are in the Group Buy, that really good savings, plus a lot more power will a full system like that. A header/downpipe/cat/piping/resonator/muffler... All for very cheap and good quality

 

A 2.2 doesn't need a 3" though. lol

 

Alright, good stuff folks. And BTW, less than 350? How much exactly? Or...

Also, is there any trouble with the O2 sensor/Catalytic converter when getting an aftermarket exhaust?
