Curious, what platform?
I have done it on my Vekta 5. First was with the DDM Dominator pipe. I used the aluminum stinger extension and rubber coupler that came with the original Baja 5T and 5SC. Then with the VRC pipe I used the silicone tubing to route the exhaust out of the cage. On my Baja 5T/SC's, I usually add an extension for the side pipes. On my 5ives, I added these all for the same reason, to keep it somewhat clean. Granted the longest extension was on the Vekta, the rest had maybe a 3 inch hose to it, if that. One may lose minimal power only visible on some sort of dyno.
