All RV-7/8/9 Exhaust, 320/360-1 with Heat Muff

A crossover exhaust system for the following aircraft:
RV-6/6A, RV-7/7A, RV-8/8A, and RV-9/9A with parallel valve (I)O-320 or (I)O-360 engines with VERTICAL induction. The system comes complete with a cabin heat muff that has a second outlet for carb heat, if required. This muff will NOT work with some starters - it was designed around the Sky-Tec LS series, and longer ones may interfere with the muff.

Supplied complete with all mounting hardware and gaskets. Tailpipe support system must be fabricated from the supplied parts for the individual aircraft. These exhaust systems are fabricated specifically for Lycoming engines, not necessarily their variants. If you have a Mattituck, or AeroSport (or similar) engine with custom oil sump or induction system then please call Van's Aircraft for assistance in determining your system requirements.
