A redesigned pipe for .21 off-road engines
Hipex introduces its new EFRA 2211 exhaust pipe, designed for .21 off-road nitro engines used in 1:8 buggy and truggy. The internal volume has been reworked to improve compression and deliver a performance gain at both low and high RPM, work carried out in particular around O.S.-based engines.
A complement to the B7 manifold
The Italian brand presents this EFRA 2211 pipe as the natural companion to its B7 parabolic conical manifold, with the combination aimed at better fuel efficiency both on the grid and during the race. No price has been announced yet; the part will be distributed through European retailers such as Wartelle Shop, Donuts Racing and RC Team.
