looking at fitting RB LSR 2into1 exhaust for my 103 stage4 any thoughts out there , performance , sound & quality 

Supposed to be as good as any, and better than most.

Like a lotta 2:1 systems can be a wee bit "fugly"

I have seen a Dyna here in Perth that had BROKEN off at the engine/crankcase mounting, that is the cases had broken off !!

NOT a good look and major shit to fix !

Probably down to fitment at the time but still...

The whole RB racing website is well good by the way. Link enclosed for the uninitiated..

Yeah.  Got one on my Road King.  Love the sound and my mechanic tells me they are the greatest for performance.  I run a 111 S&S and get 108.85 HP and 110 Ft pounds Torque.  Love those numbers man.

thanks for the info

 I like the look of the LSR Pro Stock pipe.  I assume it's noisy as hell though.  Anyone know?

Not obnoxious but the neighbours know when you get home.  Ok when riding quiet but twist it and let it loose look out.  On the highway the lads reckon 30 yards behind me they don't hear it until i give it a tweak.  Drop a gear and give it some and everyone knows.  Had no trouble with Constable Plod as long as I know they are there and settle it.

 

Look, I love the sound.  Yes it is loud but again not obnoxious.  A pure Harley sound and I think not bad.
