RB Racing has a ton of good exhaust info on their web site also.

 

I had a set on my '05 Ultra and loved the sound, it can be loud but that is up to the driver. A little too loud for my wife though.

 

I have the Blackhole,it's the quietest pipe they make. I thought it would be quieter,but the only other pipe that's quiet and makes power is Supertrapp. If you want more perfomace and more sound,go with the the Spyder. Performance is good w/ my stage1,build quality is excellent. make sure you get the smaller primary tubes and place your order. They said 6-8 weeks,i got in 7 weeks.

 

I had a pipe made by Rb racing,and yes it took a while,but I ordered it in the winter,so I wasnt in any hurry.

I think the pipe is too quiet;but my bike was bone stock.

I`m having a 117" built,so hopefully it`ll be a little louder.

Fit and finish was second to none,and I would absolutley by another pipe from them.

 

Yes I have the RB Racing LSR. 107" 11.4-1 comp and wood cams. Here is a sound clip at idle. Sound is subjective, cruising it is not bad, jump on it and it barks. I like the exhaust.:

 

That didn't sound that loud. I guess I'll have to ride up there and check the sound out for myself. I really like the look of that turn out pipe.

 

Got a reply from RB Racing... guess they don't have any bikes there to listen to - bummer!

 

You mean the guys that work there don't ride and use their own pipe????? Seems odd.....

 

That's what I thought! A little odd.

 

When I talked to them on the phone,they seemed real old fashioned.They probably dont have anything to record the sound and get it on the web.
