Right now I have the factory exhaust with the dual cats. After the Y-pipe it goes to 3 inch Dynomax Catback with single 3inch exit. I am looking at some shorty headers (guy does not know brand) but I was wondering if they would work well with the way it is now or would it be better to go to true duals. I have heard yes and no.
Thanks, Gary
