Procircuit T-4 Power

[FMFracr287]

Hey i just bought a new Procircuit T-4 Silencer for my 01 250EX. I was just wondering what kinda power gains I can expect from it and if anyone how much peak HP and or Torque it adds. Thanx!

well after i put my t-4, and K&N filter on, and took out my choke, and rejetted it gave me a good amount of low and mid power, and a little extra top end power too. but mostly it's good for low to mid power. it might not be the best pipe to improve peak power though, just adds a lot in the lower end.
