I have a totally stock 2003 Cobra and I'm looking change the intake, exhaust, pulley and tune. I am interested in a used off road X pipe for the factory exhaust manifolds and a cat-back system. I am also looking for a intake, a smaller pulley for the factory eaton and a tuner. The best case scenario would be to find someone with all this trying to put their car back stock and selling the whole package, but I any of the parts separate would be considered. Thanks for your time.
