No Dave, mine has the Aero Racing sports manifold. It is essentially the same as that used on the Plus 4 SS. It is not 100% ok on my car as even with the exhaust wrap that it now has and a 400 cell cat instead of the original 200 cell cat I still get the famous MIL light coming on for cat malfunctions. According to Omex there are differences between engines that can cause some to fail and others not.

I believe Williams have developed a sports exhaust system that functions better in this respect.

I am hoping that I will be able to get the emissions ok with careful tuning once I get the throttle bodies fitted but if all else fails I may have to change the system. Given that Williams and Omex work together on systems for the Plus 4 they would be the obvious choice for me to turn to.
