I have an ORP on my car now and I am thinking of either adding a aftermarket exhaust or swapping the ORP for a high flow cat. I am mainly doing this for sound but once the car is paid off I will be doing some kind of FI. Thats roughly 3-4 years down the line though. I figured I would get some opinions from the experts. Let me know any thoughts.
