R&B Challenge pipe. Who's got it?
Not the reg. LSR 2-1 but the Challenge?
Has no baffle.
I have a 95 with the older style SE heads 650 lift Woods cams geared 337 big carb.
Anyone have something like this?
Dyno results?
Any real info?

I just got one.I'm gonna go larger than 95 this winter and really bought the pipe for that build.Right now I run a small S+S cam with some pretty healthy head work including big valves and a SERT.Tried it out on the dyno and couldn't duplicate the numbers we got with the LSR pipe I've been running the last 2 years.I got the b-style with1-7/8 pipes.My thoughts on the pro stock pipe is the collector is too small and short for anything but higher rpm use.Everything we got came on the top end.It is the loudest pipe I've heard outside of the drags.It will have a muffler of some sort before I run it.Got stopped twice in less than 100 miles the first day for loud exhaust.
I know it will be good with a track muffler and 100+ inches,until then back to the
LSR pipe.I got 105 tq 94 hp with the LSR and 510 cams. Not too shabby for a mild build.You might get better results with your cam,but your heads might hurt unless they are opened up some.Here's a shot of the pro stock pipe.G.

That's the old style Harley premium cooler.Definitely the LSR is a better choice for the small build and still has that very distinctive sound.You'll be impressed as to how early and hard your bike will pull once you get everything dialed in. G.
