Original .12 -.15 Exhaust was taken out and .21 Savage XL Exhaust put in Place!! There is a huge difference in the 2 Exhausts with lots of compression from the .21 Exh...This Modification adds some huge powerful torque, still working on leaning it out some more...sometimes it would cut off.

.21 HPI Coupling Used. O'donnell 30% Fuel Used.
T3.0 Stock HPI Engine.
