I got a 91 S13 coupe and its my project car. Very soon I will be either doing a KA-T or putting an RB25 in it and I was wondering if I bought the 80mm TI-C exhaust and put it on my stock KA for the time being until I turbo it or swap it would the engine run fine or would it run like shit due to a lack of back pressure?
