I have an ‘18 RG with stage three, exhaust, S&S 475, and tunner. Was really unhappy with the 475 and the original exhaust setup, red line on the dyno is with Reinhart slime line duals and Reinhart 4” slip ons. You could feel the dip and the hard pull after. FM suggested replacing the slip-ons. Blue line is same setup with FM jackpot exhaust with the same Reinhart header. Best $550 I spent on the bike, totally different. 475 cam is great but needs the right exhaust setup.
Been cheaper to swap exhaust to the MK45's lol. They run great the that cam and sound great! I've heard the rineharts lose some low end as well.
