I did affect the mileage, I lost 1-2mpg in the city, car felt like it lost some bottom end, I got little more power on the top end ( not much), but loss of bottom end torque makes the car feel more sluggish, which requires more throttle feedback. I kind of knew that I was going to get which higher flowing muffler, but listened to some people that said, less pumping losses, sure
. That's ok, I am working on another exhaust set up that should put me where I was before and than some, can't wait for more bottom end torque.
