Starting a new build for an exhaust on my 2006 impreza wrx. Car has a stock uppipe, Cobb down pipe, one cat, and tanabe catback exhaust(resonator, muffler). My current plan is to take off the muffler and go with straight piping from the axle back. And eliminate the catalytic converter. Any thoughts on how well the car will perform and sound with just a resonator? Should I go with a high flow cat aswell to keep some sound down, as I want the car to be louder but not overkill. I already have 5 ft 3" 316l .065 tubing, and 4" 316l .065 tubing for an exhaust tip. Anyone who knows anything about how well my idea will work I would greatly appreciate your opinion. Pics of current settup and new piping will be posted if needed.
