Dyno proven performance. Our motto is, "In Dirt we Trust". We've been racing in the dirt since 1973! Happy Wheelies! Flo-bench tested for back pressure. Made from 304 stainless. Huge weight savings.
fit perfectly. Much louder than I expected. I'm guessing it'll pass a DNR decibel test, but I'll probably be wearing ear plugs for long rides. I'd give it 5 stars if it was quiter.
