Fits HPI Savage X, XL, 21, 25, 4.6, and SS trucks

This is an RDLogics Polished Aluminum One-Piece Tuned Exhaust Pipe for the HPI Savage X, XL, 21, 25, 4.6, and SS trucks.  This pipe is designed to increase performance over the entire powerband of the engine.  It will release some of the power that is currently being robbed by the restrictive stock exhaust system.  This is an excellent upgrade performance pipe, and it looks very nice too!
