PSE - yay or nay? in 981 Posted Wednesday at 08:40 AM · Report reply Oh yes!!!! I LOVE my PSE! When I first bought my car the exhaust sounded really quiet and I was a bit disappointed. I got my OPC to look at it and the exhaust valves were seized shut. A brand new PSE was fitted and it sounds incredible. I would definitely go for it. I never drive my car with the roof up, and rarely do motorways, so can't really comment on the noise under those conditions. But I do find it considerably quieter with the exhaust off.
