I have an 04 LS and I'm wondering does anyone make a catback exhaust kit for the year I have...I know there are some differences 03+...any advice would be much appreciated.
I get about 17 mpg in town with my 04 V8...with about 24-26 on the highway but I'd probably get better in town if I didn't gas it so much...I have all ideas after I replace the stock air filter box setup and exhaust it'll probably be around 15 mpg in town and maybe better than 26 on highway.
I can't wait to see what happens with this car...just got a 04 LS 3.9 and am looking into some intake and exhaust work...anything as quiet as it is has to be gasping for some more air.
