I've had my 03 for a year now. It came with a custom exhaust when I bought it. I'm not sure of the brand of exhaust (I think it has "bp" lettering on it...sorry, not real technical here).
I pulled out the baffle the other day, and it sounds great. Just wondering if in doing so, will it affect my gas mileage in a negative way, other than me romping on it? Thanks.
