I'm getting sick of my street sweepers. They rattle like **** and I know they're not helping hp/tq. I've read here that the V&H Propipe is the single best for performance, but, well, I don't like the look of it. I don't like 2 into 1, even though it is better. I really like the look of what I have, but they suck for everything else. The big shots are nice, and they have a crossover in them, which is almost as good. How much of a hp/tq difference is there between the bigshots and the propipe? Did they ever decide to make the 2 into 1 Big Radius? That is one 2 into 1 that I would put on my bike. Real cool you can find it for the raider no problem already, and our bikes are in their 8th year. If anyone has dyno time on either or both, I would appreciate it.
