View Full Version : XP-500 Tuning Tips

I recently bought a used Super Trapp closed cap muffler for my 2002 Yamaha XP500. Is there any tips on how many plates to take out or add for overall power?? The only mods to it is a BMC air filter. Appreciate any help...thanks!

Start tuning with HALF the amount of discs supplied with the muffler. Follow the general tuning guide and review the FAQ's at the website.
