So I am considering these two mid-pipes because they have a high flow cat that is durable from what I have read during harsh driving (autocross/tracking). My guess is that the rp supercat is obviously louder, but will it have any rasp at high rpm cause it doesn't have a resonator? What are your guys opinions on these two pipes for those of you running these?
