I was wondering if anyone could tell me whether this was a race engine or not.
and I was looking at different mufflers(pipes) for this. I wantto run an APC 7.4X7.5 at HIGH RPM. will I be better off cutting the header to get the RPM or getting a new 3246 pipe.
I also found a 3235 and a 3248, would these work better?
I am wanting to put it in a Q40 model, thats why I am using a small diameter prop.
Thanks ahead of time .
