Vintage Speed stuff looks pretty but that's where it ends. I'm baffled by all the VS exhausts I see on performance engines, nothing is going to strangle your motor like a VS exhaust.
As for shifters, I was at a show and a guy asked what I thought about my CSP, I said it's the best I'd had (I've currently got an Empi, Scat and Berg sat in the garage, for sale soon) and he went on to tell me how his VS shifter broke while he was in the south of France on holiday and he had to be recovered, with his bus coming home 3 weeks later. The fact that they have a "version 2" should be a huge red flag! What was wrong with version 1? Berg shifters get the best reviews and are superb,but I prefer my CSP. The Scat, with a slight tweak, was excellent for the price.
