Great match of your TRX 3.3 traxxas has done there homework with this pipe!!!
I converted a 2.5 Maxx to 3.3 spec... I had a Rd lodgic rear duel exhaust... Let's say it didn't keep tune well and didn't have the bottom end grunt that a monster truck needs...the resonator pipe FTW!!!
Bought this tuned pipe to go with a Traxxas 3.3 engine for my dads old .15 T Maxx. The upgrade fit perfectly. Once we got the engine broken in it ran very well and wasn't too hard to start. The engine is pretty fast and this tumed pipe works well with it.
