I have had many Harleys all with straight pipes. My 2011 XK Coupe has a good sound, but I would love to hear it open up with electric cut outs. I am looking for a shop in the Washington Metro area that knows what they are doing. Any help?

 

Have it on my 4.2 n/a and love it!

 

GOM, call Fanthom Works down in Norfolk.
