Anyone have a how-to on this?
I'll give you the condensed version.
Remove pipe from bike at the header/cats.
Remove end cap, 3 cap screws and she slides right off.
Mark desired length, make sure to keep same profile, this is important when it comes time to weld things back together, use blue painter tape, more then you think you need.
Grind weld off of end, this is the most time consuming aspect. Once the welds are gone pull the innards out, there will be a mesh wrapped around the inner baffles, carefully unwrap and set to the side.
Measure how much you will be removing from the out side and take an extra 1/2 inch off.
Next, using the cutting tool of your choice (Don't rely on Kirbys teeth, Brian cancelled his dental insurance years ago) remove the excess off the outside, being carefull to follow the correct contour. Check the fit of the baffle and can, if everything fits, cut the mesh to size, I wouldnt recomend using your wifes best scissors. Once done wrap the mesh and do a final fit.
Weld things together.
Touch up any welds and burnt paint with some high temp header paint, I painted both end caps a gray color (NOT SILVERDAMMIT, BTW) and can to match.
Reinstall and enjoy. The benefits really are more looks than anything, I did have a nice mellow tone, nothing harse or annoying for sure. The cats are still in the collector, so there is still lots to slow down the gasses.
Remember, if you don't post pics, it didn't happen
