RE: MVVS 35cc: fitting MVVS tuned pipe and header
The MVVS 3268 tuned pipe has the 9" long header 3269 paired to it. This is best for standard use.
Fitting in the fuselage IMHO does not belong to MVVS support, but is a question of general nature.
However, having said that, the pipe runs straight under the engine Center line with the cylinder fitted in the 7:30 o'clock position.
