Darren mine is very much like the ones Mike R sells, Never actually seen one of his but I believe they are very good, dont know how they compare to mine and not to bothered as i'm hapy with my results to date, I can do them for a standard TB or a BMW 3" TB, I have will have two available in the next couple of weeks as i've done 10(7 possibly 8 taken for) for people that have kept on at me and wanting them Yes they use the standard inlet runners but I advise porting work to be done to open them up a little.
