I have a miltek system with the miltek cat replacement pipe. Hoping i can fit the standard cat back on for MOT time?
my cousin got full milltek cat back system fitted on to his 182.. He's been complaining how slower his car is compare to other 182's. i raced my cousin other week n i could see its much slower than mine He's been told that milltek system would increase his bhp but its has decreased instead.. any tips for him??
