I just swapped out to long tubes, h-pipe, mac produmps from bbk equallength shorties, h-pipe, and flowmaster cat back. It is obvious that I picked up time (I think 1 to 2mph) so you might pick up even more. And the sound from the produmps is without a doubt the best sound I have heard from a 5L car.
