Hey I'm new to 6gen and I have a question about the obx hi flow cat. I have a fujita CAI, 4-2-1 megan racing header, and 2.5 inch JDM catback exhaust. I was wondering if i installed the obx hi flow cat if I would gain a little power or lose a little power due to lack of back pressure. I have also been considering a test pipe any suggestions on what I should do? Anyone have any videos of hi flow cats or test pipes on there cars?
