I'll put a call out for you but the guy I know is a pack rat , he has 8 of these things . I built one about 10 yrs ago ported it for top end , he had s toomey exhaust on it and a pwk . This thing was fun even with my fat ass on it. You can get these engines to scream like a chainsaw on crack and I'm sure with pipe builders today get a set of handconed exhaust to compliment porting
