calling from across the pond !. I need some advice,ive got my xb12 in for the first service and have a race ecm to be fitted whilst its in and get the tps set,the question is will the exhaust valve still work on the standard muffler ? if not will I loose much power? .Im waiting for the Sebring exhausts to come in to Trojan uk which I can fit later. | ||

I would hold off on the ecm install until you get the pipe. The race ecm does not work the valve so basically what you will have is a straight pipe. you will lose power in spots. not a whole lot I would think but yes you will lose |
