I’m new to the forum and recently got a 2018 Freewheeler. When i bought it from the dealer I had Supertrapp stout slip-ons installed. Trike sounds great when giving throttle but too quiet all the rest of the time. Dealer tells me that to get the sound I want is going to cost $1500 to get it done. They say that it requires a new header pipe with cats removed, a tuner, and 6 hours on the dyno. So my question is..what’s the real deal? What can I do without spending that much. Remove the packing? Hollow out the cat? Any help would be appreciated.
