RB Racing LSR Pipes : V-Twin Forum: Harley Davidson Forums

BadWeather · 10-22-2009, 05:52 PM

Does anyone know the differences in torque and noise between the standard 2:1 LSR and the 2:1 Pro Stock. I am not interested in the Spyder or Black Hole versions as I'm sure these will be to quiet. I'm currently running a D&D Fatcat and OK with the noise. I'm concerned that these LSR pipes will hurt low end torque and are more designed for WOT riding then the cruising that I do. Thanks in advance.

I don't have numbers for you but I ran a LSR on my bagger for about four years. It wasn't too loud but I am deaf. Bottom end was still good with it. I would still be running it if I hadn't totaled the bike.

Search this section of the forum for posts by "Nowhereman". He has a solution. I don't remember
the name of the company but they have a cone or baffle you can install in the RSB Pro Street.
Better torque, better sound.

I have the baffled LSR, turned out, 45 down and highly recommend it. Sounds great, well balanced, no dip what so ever off the line, runs well right up to the rev limiter. Blows away my old Rhinehart 2-2. Form, fit and function are right there. The key is to match the primary size with your engine. I went with the 1.75's and they are right for my 103, probably right for your bike too.The 2 inch primaries don't come into the picture until your pushing 110/117 CI, if you get greedy and go too big with the primaries, then you probably will have a low end dip problem.

The prostock is really cool, with the quite riot baffle install. Dwood has that setup and loves it. Either way you will be good.

Some here complain about R&B CS... I had no problems. Ordered my pipe in Dec. and received it in 3 weeks as promised and never looked back.

I really like mine,a huge improvement over the V & H 2-2s I had,Mine is the C style Pro-stock with 1-3/4 primaries and a Quiet Riot baffle,"disc only"..Go for it, I don't think you will be disappointed at all,that is if you don't mind a little volumn,and I can almost guarantee you will love the sound..
I listened to a bunch of pipes before I decided on this one, I only wanted to drop $800.00 one time..LOL

Thanks everyone I had heard that the quiet riot baffle people were having some legal trouble and could not sell any until straigtened out. Their web site is still up although and so is the price $129 bucks. So from what I gather go for the Pro Stock and have no worries for a bagger.

Legal stuff is long gone now.
They sell both types, the single hole or the multi hole.
I tested both on my 127 and went with the single hole unit.
Smaller engines under 100 inches would do better with the multi hole unit.
I makes the RB pipe just about perfect if you like torque, HP and sound.
If you want a quiet set up, don't go this route.

BW if it were me and it isn't , I'd go LSR reg baffled 5 inches longer turn out rotated 45 degrees in whatever finish you want and when you call you can ask about primary tube size then. No offense to Nowhereman meant at all but I would not add any thing to the system. The Prostock is evil loud if that is what you want, the baffled LSR is pretty fn loud when you jump on it but not too bad when you are just cruising. This info is worth exactly what you paid for it...nothing.

Who's over rating the LSR? Have you had one?

You have a D&D fatcat don't you...

qtrracer · 10-23-2009, 07:32 PM

That is exactly why there is more than one choice of exhausts.There are other 2-1s I don't like, but thats my choice,and believe me, I heard enough tractor sounding systems to guide me where I wanted to be.
Have you checked out bowsharley's sheet? Looks pretty impressive to me,I think it wen't over 120tq with a 107.
Throw that in with superior quality,fit and finish..I just don't see over rated,thats JMO.

I teetered back and forth between the baffled one and the
pro-stock and when Laser went baffled LOL,I figured what the hey,now we can have an A and B comparison.
