I'm looking at getting an RB Racing Exhaust.... I've made up my mind that I'm going to get their exhaust. My question is this:


How much louder is the LSR over the Black Hole?


This will be going on a 00' FLHTC with 509 cams.


I've ridden my dads Heritage and he has the +5 LSR, 95" motor with 510 cams.


Just trying to get a feel on how much the sound difference is.

The LSR has no packing material inside a muffler, it has no muffler at all, so to speak, only a small metal baffle inside the collector. If you like how your Dads bike sounds then there you go. I had a LSR on my FLHX and after I did some motor work IT WAS EARSPLITTING, lol. Had to go another direction. Found a quieter 2-1 and picked up 10hp as well after removing the LSR. I had the 00-1123 LSR on mine. I assume the Black Hole is a normal sounding exhaust due to the sound level of the LSR that I had.

 

I'm running an LSR-C style they are mid too top end pipe. Not the greatest on bottom. Aren't the 509's a low compression low end cam?

Also the more compression you have in your motor the louder the exhaust will be..

But if your looking for loud, yea go for it. Don't know the difference between the lsr and black hole... I'm sure some one art rb racing can tell you... 310-532-4116.

 

the 509's are a "high lift", short duration cam, they bring the cranking PSI up about 10-15 psi....
