So I'm planning on getting the CorkSport power series exhaust, and they offer a high flow catalyst. I was just wondering if any of you guys have gotten this, and if it's worth the extra money?
I asked one of the Corksport reps about a P5 exhaust a few months back, and they no longer make the exhaust for P5 or Sedan, their only one is the 80mm exhaust for the MSP.
But that is buying it new anyways, it could have changed since then but as far as i know that is how it is still.
