Does anyone recommend upgrading to the 5485 Tuned Pipe Dual Chamber Resonator? I'm running this thing with some buddies who have a small grass/dirt track with some little jumps AND ALSO on the street when we get that "speed bug" and want to go full throttle.
So, knowing that we intend to do a little of both, do I just leave it stock or is there an exhaust upgrade that covers the whole rpm spectrum? It seems like you either get something for low rpm or something for high rpm, but nothing that helps overall performance.
Any thoughts from folks who have made exhaust modifications?
