Alright, so I just payed off my '06 LGT, and I'm wanting to get into some modifications. I want to start with the exhaust but I'm not sure how to go about it. Do I need to buy the entire new exhaust system? Or can I install it piece by piece to avoid paying $1000 - $1500 upfront. And another question that popped into my head would be about the O2 sensor. Would I have to get a new one, or get it tweaked to adjust with the new exhaust?
Sorry for the dumb questions, I'm not going to pretend that I know things that I don't. Thanks in advanced guys.
