A nice piece of stainless steel engineering. It fitted well between an IL Motorsports 4-into-1 manifold and a standard backbox. The centre clamp, however, was too big. Even when fully tightened it didn't grip the pipe join, so we ended up having to weld the 2 halves of the midpipe together. There is no O2 sensor boss after the cat, which is a pain (I'd rather have the second O2 sensor boss than the EGT boss before the cat). Note that the O2 sensor boss that comes with the manifold sensor extension kit isn't made from the same steel as the midpipe, so welding it in will create a corrosion source. The front of the resonator is only 2 or 3mm away from the IL Motorsports chassis brace that I have fitted. They don't seem to be making contact, but I'd have preferred a bit more clearance given that IL Motorsports made both items. When fitted with the 4-into-1 manifold the increase in power and torque (after a remap by Skuzzle Motorsports) was significant, but the increase in noise was minimal, which is just what I wanted. I have yet to see if the car will get through the MOT emissions test with just the sports cat. Rating: 5 of 5 Stars! [5 of 5 Stars!]
