just swapped a jdm b18c type r motor in my dc2. My mechanic had to use my gsr dc sports headers. I also have the magnaflow 2.25 inch cat back system. do i need to change my exhaust set up at all for the new motor?
why do you think your exhaust set up needs to be changed? i mean, you benfit from a slightly more free flowing 2.5" setup, but why waste the money, particularly on an NA car- if everything lined up and the motor runs properly i wouldn't bother personally
