Hey guys My 09 streetglide is "for export" canadian bike.Cats are supposed to be in header. Took my right muffler off today and ran a steel rod all the way up to the curve going to front cylinder. No cat in header?? I removed the left muffler and noticed a difference with the right one. The exhaust end is blocked about 6" in, with holes in the short pipe to the end of muffler.If you look in the inlet side ,it's hollow but with a mesh or screen type material on or near outdide tube diameter. The right muffler has baffles and is not hollow like the left one.Also most of the exhaust seems to exit left muffler.Could this be "cat in left muffler" exhaust? If the cat is in the left muffler, would slipons require a stage one download,or should I still get pipes and slipons? Any comments welcome. Thanks!
