No downpipes for me... at least not yet. My dealer are a bunch of sticklers and will void my warranty if I put down pipes on. I'm still fully covered if I just grab an exhaust. I've heard gains of 15-20hp from some of these exhausts out there and weight savings of close to 70 pounds with some. Anyway to slim these monsters down will help. I noticed a difference just with and without my spare.
