Oh Dear. Sorry to hear that, Andy. You've had no luck with this have you? My Playmini Manifold/System's been on for well over a year now, and I've had no trouble at all. It's still sounding great and no emission glitches. As you said, Dastek's Manifold sounds like a bit of a 'scrapper', but you were aware of that and at least they sorted you out OK, which is good - AND those PM tailpipes do look the business, along with the improved sounds.

I'd still recommend folks in search of improved exhaust flow and 'TVR sounds' to fit a Playmini manifold - but then maybe I shouldn't so that my motor still sounds one of the 'nastiest' on the club runs!
