Hey everyone. The next upgrade I want to do on my g6 are dual exhaust pipes. I won't be able to do it until summer again (in college right now too busy) but I've been doing my research now and I just have a few questions to clarify things and increase my knowledge. The first question is, what are all the things I need? From what I've gathered, I need a muffler, valence, and I want a glasspack to replace the resonator. Am I missing anything? If your answer to that question is no, then it brings up my next question.. I looked online and single in and dual outlet mufflers look like they would create two exhaust tips on one side of your bumper, instead of one exhaust tip on each side(hope you understand what I'm saying).. Is that true or am I looking at the wrong thing? While I'm at it can someone recommend some mufflers? And don't put me down too much I've never been taught about cars and how to work on them. I've been trying to learn myself through research and using my first car as a learning experience so when I get a sports car I can really do some performance work. Thanks for any and all help! Also what cost range am I looking at to do this?
