Not sure if my situation pertains to drag racing or not. But I'm in the process of building a

421 4 mill cub and I was thinking of running a fmf pipe. Cuz I ride a mix of trails and sand. I wanna keep some low end with a helluva top end kick! What do u guys think?

Rico run small bore pipes if you were over 440cc's than you would need the big bore. It don't matter if you get in or out of frame pipes. I prefer the out of frames cause they look so much better.

I think since I don't know you...I don't know if you're kidding or not...that being said, I hope you are.

Rico it depends on your porting. Nate has dyno runs that show BB pipes make more hp for his porting. But other builders will tell u they port for SB. They both have thier pros and cons. Ask who ever your having port your motor what his port runs best with
