Just getting around to installing a used set I got off of the classifieds here, me being the maroon that I am I assumed that the exhaust cans installed the same way as the factory ones and had ordered a new set of exhaust "doughnuts". Upon test fitting it looks like the Arrow cans slide on with a metal-metal fit with no exhaust "doughnuts" and use a smaller exhaust T-Bolt clamp? Pretty sure that the package came with the new hanger hardware and possibly the T-Bolt clamps but I wanted to confirm before I go tearing into the winter "pile o parts".
They are slip-fit. Run a thin bead of high-temp (I use Ultra Copper Permatex) silicone around the end of the inner pipe (should be the forward pipe) before assembly. There will be a small bead of silicone pushed up by the outer pipe. LEAVE IT THERE, don't wipe it off. In a few hours, use a razor blade and trim the excess bead off after it's completely cured.
yea no spacers needed.. arrows are metal on metal and come with their own clamps which are lighter weight.. overall with the arrow pipes you will save 3.5 - 4 lbs over stock.. also, you might receive "db killers" which are not db killers at all but are just spark arrestors that plug into the front of the cans not the ends and do nothing at all for sound .. I like quiet pipes.. and the arrows are loud.. I run mine all the time though because they are awesome.. and they really wake this bike up big time esp with the ecu
Nope, they sure don't. Unless the pipes are misshapen and/or beaten stupid and don't perfectly seal themselves any more. Like mine are.
