[Screeper]

Do what I did. I had the extreme flow (May have been a bad one) and my performance dropped to zero. It then progressivly got worse and worse until it was scary to drive. Third trip to dealership they found temperature in front of exhaust muffler was off the scale(blockage). It was burning up the sensor. Dealership was nice enough to let me have an old factory setup that they had laying around from anouther exhaust swap out. Never drove better. Remember an exhaust system is almost a quarter of the way to a supercharger. That will be the way I go if I get the performance bug again. Good luck
