Macs Tuned Pipe .19-.35/3.5ccTower Stock# LXZ558 • Manufacturer Stock# 1120
Notes from our tech department:
quiet/muffle an engine and INCREASE the power and RPM of the engine. It is
made of aircraft grade aluminum. This pipe REQUIRES an exhaust adaptor (header)
to fit the engine (Macs makes a bunch) and a piece of silicone tubing (also
called a tuned pipe coupler).
Outer Diameter: 5/8" (16mm)
