Hey all. It's tax refund time, so that means christmas for The White Devil(my NA 242.) The planned mods include bilstein touring shocks+struts, 242GT frame stiffeners, flat hood+modified 78 grill, IPD sport exhaust, K&N air filter, and a long needed fuel filter, OD repairs, and tie rod(yeah, I'm aware of the inherant dangers of not repairing) I'll be doing some MPG and 0-60 tests before and after for a better understanding of how my $480 were spent, but I was wondering what others' experiences have been with the IPD sport exhaust. (I may be opening up a flame war here, but then again, this isn't OPINIONS ^_^) Will I be getting more out of the air filter than the exhaust? Am I throwing away money when I could just get a turbo exhaust, installed, for the same price? I assume these will compliment each other nicely. Also, does anyone know of any type of "hi-flow" fuel filter? This <20MPG is killing me. As always, I appreciate the input.
