Just wondering who has either of these exhausts as I think theres not much life in my standard system. Ive found scorpions site with some technical stuff which I dont believe lol. They rekon power increases of 192 are possible with the de cat. Im swinging more towards scorpion at the moment but gonna be boring and probably go for the cat back. Anyone got any realistic figures and also more info on the milltek, performance and quality and reviews on the scorpion. Opinions on both would be appreciated.
