MOT rules now say if it had a cat when manufactured, it must have one now, in the original position. I'm not sure how they'd know a modified one TBH, but I think they want to stop people using a cat as a rear silencer (where it does nothing really)
Looking at buying a stainless steel mani as mine has cracked,spoke to ktec and they told me as long as the second cat is in it will pass the mot know problem!any advice? What do u think? ( new member by the way, hi everyone )
Ktec said it would run ok! gonna get aldon motorsports to map it sometime! cams, head work first,they did my 106 rallye 160bhp track car and my 172 cup 208bhp really rate them.
