NG900 & OG9-3 Performance, Mods & Tuning
This morning I installed a Maptun 3" downpipe and a Maptun 2.5" catback exhaust.
It all went pretty well, took a couple of hours. The only problem I really had was getting the midesction of the catback out and in over the chassis, but only bcause I couldn't get the back end quite far enough...
