I have a 900rr header pipe from Delkevik that can be set up for slip on or bolt on silencers. The OD of the pipe at the silencer end is about 2 3/8" and I can't find any dimensions for what will fit as a slip on. Any help will be appreciated.
I used a 63mm inlet Scorpion Street Extreme. The really hard part is most of the specs don't list dimensions only which bike it is for. Find something you like and call and see if they can give you the dimensions.
