Well, parts of it are. Do you know where that exhaust header came from? I am trying to find the aluminum part that bolts directly onto the motor. Got a special project for it, but I need more of them for test developing. Can't find it anywhere on HPI's site. Oh, and which pipe was that again? You wouldn't believe what that pipe does to a T-maxx. WOW! The midrange and top end pull so strong on a trx 15 it's amazing. Runs good on the SS also.
