Default S&S MK45 vs Rinehart Motopro 45 vs Khrome Werks 4.5 vs. Kerker Stouts
I had V&H Ovals on my 2008 Ultra ... they were about right for loud, wouldn't want them any louder but would have liked a bit more of the deep rumble ...

For my new 2018 Ultra Limited I'm considering:
  • S&S MK45
  • Rinehart Motopro 45
  • Khrome Werks 4.5
  • Kerker Stout 4"
  • SE Street Cannons 4.5"
How would you rate them for loudness against my old V&H setup? Any other comments on any of these? Pro's/Con's?

Thanks

I had the Khrome Werks, Street Cannons, and RCX’s 4.5 and now MagnaFlows.

Khrome Werks...very quiet, maybe a step above stock. Excellent chrome

RCX’s...nice sound, much better than stock, chrome was mediocre

street Cannons...nice sound, got much better after a couple thousand miles, that’s for sure. Nice and loud when romping it,but could cruise quietly

Love the MagnaFlows..I also love the MK45’s, both great choices

Mine were all stage 1 with a Harley tuner..I didn’t retune for each one. The Street Cannons performed best. The MagnaFlows went on with stage 2

I have the Rinehart, kept the stock headers. They are great and didn't need a tune with just slip ons.

No decel popping , none at all on the M8...didn’t matter which slip ons I had. That was a different story on the 2014, 103 motor...it was a problem on a couple sets, I’d do an “auto tune” with my FP3 and get rid of it “mostly”

here’s my bike now..stage 2 and a “couple” of other things

Thanks, makes me hopeful, in the end I went with the Rinehart MotoPro45's, they arrive Friday ... looking fwd to seeing what they sound like. I had decel popping on my 2008 and hated it, nothing I could do seemed to tune it out, in the end I just lived with it, good to hear this won't be an issue. Your bike sounds awesome by the way, well done.
