I'm running V & H Dresser Duels w/ the 3 .5 Rinehart slip ons. I've got a 103 build and my bike is plenty loud. Real nice thunder crack when I give'er the whip and mellows out at 70+ crusin speed. With that said I'm getting the 4" Rineys this Friday to get a little deeper base. I'll post a sound clip of my 3.5 vs. the 4" next week.
I'm running the V&H Power Duals header pipe with the new 4" Rinehart Mufflers on my 2010 SG (96"). The sound is perfect! Louder than the mild set-ups, but not raspy and obnoxious. Very deep tone. Performance is excellent with the stage 1 air cleaner and Power Commander 5 mapped by Jamie and the Troops at Fule Moto. Theres no way I could have nailed-it any better than I did with this set-up ...just got lucky I guess. Or, could have been the countless hours of reading the threads here!
I was looking at the dresser duals with my 3.5 Rineharts . Are the 3.5 Rhineharts deep sounding or tinny? I see you are looking for 4''
for deeper sound
I went with the bassani true dual headers with rinehart slip ons i got alot of bite when you lay on them but while cruising they are quiet enough to keep law enforcement at bay i am very happy with it
I had the true duals on my 05 RK. Nice deep rumble sound. I now just put the Rinehart Extreme true duals on my 2010 EGC. Same deep sound and a little louder than my 05 Rineharts. Nothing tinny about Rineharts.
