salem said:I can't say for anyone else but Charlie at Pro-Speed did a lovely exhaust for my 172 my friend Chris brought his Trophy and took it straight to Pro-Speed he said it was much better then the one he had from K-tec.. SharkyUK and I will be taking the Trophy to Pro-Speed as I know he will do what we want and his customer care is the best I have known.. but it does help that I dont live far from Cardiff
