After being contacted concerning the possibility of replicating the custom X-pipe he produced, Steve explained the extent of work and parts/tubing fetching he went through. Still, he agreed to sell me the X-pipe and at cost (!!!). For all that I must say it herw, thank you Steve.
The X-pipe was fitted today and the fitment was perfect, I took a photo on my mobile which I will post once Pmartins converts it for me. Tomorrow I'm taking the car to the same dyno for a X-pipe vs No X-pipe comparo...all in the name of science!
