Hey guys,
Just had to show off Mariah's new toy; a 14' x 3' flame arrestor. It was $100 at Summit Racing. And yes, it is a USCG approved flame arrestor. It gave me about an extra 100RPM/1.5mph on top end. Regardless of that, it was worth it for the Tim Allen "grunt grunt" factor over the wimpy 9" arrestor.
Cheers,
DKJ
