Also you lose lower end torque but gain very little HP at the high RPMs. I don't know how true the HP gains are, but you will have a torque loss but the sound is sooooo worth it. I watched all Nick's videos (thanks) and it sounds even meaner and better in real life. Great purchase.

Also Khoi has very fast shipping (also free).
