This is the RDLogics Blue Aluminum Dual Exhaust System with Twin Stingers for the Traxxas T-Maxx 2.5, 2.5R, and T-Maxx 3.3 monster trucks.  Not only will you see an increase in power and performance, but these look great too!  The sound of this is MUCH better than the stock exhaust as well.

Fits Traxxs T-Maxx 2.5, 2.5R, and 3.3 (both model 4908 & 4909) 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.
