[6speed_M2]

I’ve gone through many different set ups between catless/HJS 300, m2 resonator + MPE, MPE w/o the res and nothing really worked. The res did not affect the highway drone but it did a little to help on the street.

The worst setup I had drone wise was the stock DP and MPE. The best I would say is the HJS+res+MPE, although I’m sure a stock exhaust would help even more.

Catless and HJS didnt change the drone for me to any noticeable levels but it did get a little quieter. Nothing really helped. I think the issue is in the single pipe exhaust and the design of the MPE only makes it worse than the stock muffler with the drone.
