Just found the V-twin Forum. I was doing some research about changing out the header/exhaust on my 2010 RKC to eliminate the cat converter - and I found the forum. Seems like a great site! Look forward to mining all the wealth of experience and knowledge out there because I'm new to this, even though I'm 61. I was a biker 40 years ago but recently got a Harley. Back to the header/exhaust change out. My 2010 RKC is stock. I want to eliminate the cat and open up the engine to breath better. I invite all good advice.
