You need to be looking at the exhaust side of things more than the air filter. There are offerings from MMC (Stage 1 system), G56 and Krazy Horse at the moment, plus one or two others that involve a bit more fabrication.


Try cutting a 38mm hole in the front baffle on the standard exhausts first. You will need a hole saw & 2 x 30cm extensions to reach them. This will make the exhaust a bit more free flowing & a bit noisier but not a affect getting an MOT. Little cost & may be enough for you.
