I recently installed new mufflers (tanabe medalion) and I realized that there was a heavy loss of power in the low range. I've researched this alot and it may be due to pipe size; however, the pipe size is 2.25" crush bent. I've noticed a loss of gas mileage too, not due to any lead foot or anything after installation. Anyone ever had this situation?

that's what i'm afraid will happen if i change the stock mufflers but their so heavy. i even noticed that my car has more power and better gas mileage when i switched back the stock 16" rims and tire size. and uses way less gas when i run the ac

If Tanabe's are free flow muflers, then that is your problem.Its more back pressure loss from restrictive muflers and resonators ,not much from the piping.
