Does anyone have the BCT Monster Baffles installed on V&H pipes (True Duals), if so did they actually increase performance, do you like the sound and did you have to re-map?

 

Not exactly. I have just installed them on my '07 heritage. Running straight pipes w/ head pipe baffle. I'm guessing your putting the baffles on the '08 FLSTC? If so, the stage 1 upgrade isn't specific on what aftermarket pipes you use. The map is the same for all aftermarket pipes. As for the increase in performance....My guess would be, not noticable. I haven't seen the exact baffle for your application, but not sure if it's worth the $100. If you're going to get 'em, ride your bike for a while (a tank) with them installed and check the plugs. Or just ask your mechanic. (non-harley)
