Just a quick question , I have a 2009 Cobalt SS , did a muffler delete and was thinking of going full straight pipe. Will these Cause any problems ? I heard about the check engine light go on but this can be fixed with a non fouler. But do I have to buy an specific one or it doesn’t matter ? Thanks in advance

 

you need to bypass the o2 sensor because you will fail inspection.but its going to smell horrible with no cat and resornator and mufflers but it will sound sick though.right now i have a muffler delete and soon i will be getting a catted downpipe with the turbo xs rfl cat back exhaust.

 

Ooo ok , thanks brother !
