So I recently removed the muffler from my 2012 and to be honest with the factory resonator on there it doesn't sound half bad. Things I have noticed...my mileage dropped by 1, the engine rpm seems to jump up to 5k alot faster than with that big can on the back. I can't say I noticed a drop in torque, but I am sure there might have been.

Question is I am just going to replace the resonator with something that has a little back pressure to get my 1mpg back. What mufflers fall into this category and would possibly fit in this area of the factory resonator?
