what brand downpipe for a cobalt ss sc is good. i want a 3'' and it might be awhile before i can replace exhaust so if downpipe is switched can exhaust stay stock?

thanks guys

 

3" ZZP is decent, that is what I put on not long ago.

Lmfao theres been a lot of these threads posted lately. Just check the faq section above the threads in the LSJ section. Lot ofuseful info in there.

 

I would recommend a 2.5" catted dp over a 3". I have a header and a 3" catted dp with a stock cat back and my car sounds like ****.

 

Go with zzp high flow cat, either 2.5 or 3, also if u plan to do anything in the future outside of just of exhaust get an extra 02 bung added for a wideband later

 

I have a ZZP 3" Catted DP to a 2.5" exit mated to a Corsa Touring Catback, and it sounds fine. But definitely get the extra bung and just plug it until you get a wideband.

Oh, and use the search function haha

 

Use the 2.5 high flow catted one. This is my only engine/exhaust mod because my stock flex pipe broke. Now it's raspy as ****. It will probably be pretty terrible with no cat or a 3".
