This is the RDLogics Titanium Anodized Aluminum Dual Exhaust System with Twin Stingers for the HPI Savage monster trucks.  This will fit the Savage X, 21, 25, 4.6, and SS trucks.  Not only will you see an increase in power and performance, but these look great too!  The sound of these is MUCH better than the stock exhaust as well.  The tips exit below the rear bumper for a custom look.  The rear-exit exhaust also helps keep the truck much cleaner.

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

These perform great, and they look awesome. RDLogics parts are built with the racer in mind, and they are constructed of the highest quality materials. These are a must for high-performance vehicles and people who want the best.
