your on the right wavelength there garry, yes ive added a few centimeters in a couple of places the help fitment, but more importantly to get the length needed.

I learnt from Martin at chiselspeeds when he trys his ads 3/5/6 he has them on the wall as a length of pipe with the combustion chamber but can fit each one by the two exhaust studs and has them sticking out from the side on the dyno looks weard but you can see the length difference in each pipe which we no is so important you'll sort it holty you have engineered harder projects than this
