reason I ask is because custom pipes in Donny can make me a system pretty much similar by the sounds of it to the motordyne system but about 600 less! I have spoken to a few people that know of them and they all say there work is top draw and been doing it for 20 plus years. I had a look at the gear they use etc and its looks spot on to be honest just might not have the blue titanium tips that's all, so im considering it as an option later on after I sort the RS wing project.
