More power to you trying to do wheelieâ€™s on a Harley â€“ youâ€™re only a heart beat away from â€śstoppieâ€™sâ€ť - hopefully Iâ€™m just kidding. Iâ€™ve watched enough â€śgee, I didnâ€™t think that would happenâ€ť videoâ€™s of kids on Crotch Rockets to know that ainâ€™t for meâ€¦â€¦..
Anyway to your questions:
Noise Level â€“ I think they are just about right â€“ just about the same as my Big Shots Staggered pipes were. I measured the noise levels on both sets of pipes with the same calâ€™d audio meter from work.
Hereâ€™s the link:
My bike is a stage 1 â€“ stock 88B, EFI (with HD SERT) bike
Probably if you want the best performance pipes youâ€™d have to go to something like the â€śSupertrappâ€ť style disk exhaust & dial in what you want. Iâ€™ve heard about others that offer performance increases also. Now for me I wanted something that looked great on the bike- period. I also wanted a quality product â€“ chrome, construction, & customer support â€“ IMHO Vance & Hines offers that â€“ so I sort of limited my selection to their products. Before the Big Radius came out â€“ I really liked the Big Shot Staggered Pipes I had & I certainly had no problems with them.
Of course, as youâ€™ll note, in previous posts â€“ when the BR came out I wanted them big time â€“ only pipe I ever bought without hearing them first.
The link below shows the dyno info of my bike with the Big Shot Staggered & Big Radius pipes installed â€“ same guy, machine, computer doing both runs so even if the absolute numbers are in question, the relative numbers are correct.
Youâ€™ll note that the BR have more Torque/HP in the lower RPM ranges than the BSS pipes do â€“ for me where I run that makes more sense to me (where I normally drive). I normally donâ€™t drive down the road at 4,000+ RPM - @ 75 mph Iâ€™m pulling about 3,200 rpm.
The construction of the BR pipes is a stepped down design which give more back pressure & therefore more HP/Torque in the lower rpm ranges.
If you are going down the hop up route â€“ 103â€ť, 113â€ť, ported heads, wilder cams, etc the pipes might not work outâ€¦.
Below are a couple of other links which might be of interestâ€¦.

Well good luck on the huntâ€¦..guaranteed to cost you more than you thought â€“ but thatâ€™s why I keep practicing â€śThis is a Hold-Up!â€ť. Time to go out & snag another Lotto Ticket!
