Recently fitted my turbo back exhaust and im quite suprised with the difference it has made as i wasnt expecting much performance difference until i get it custom mapped but im quite happy with it, was a right pig to fit though as the bolt holes on the downpipe were that close to the pipe itself that when i put the 17mm nut on there wasnt room for a socket to be fitted over the nut without fouling the pipe itself so had to use a crowsfoot which took me forever to tighten them! did anyone else have this problem when fitting there blueflame system>?
