    I don't live in NY, but good luck with that... you might have difficulty depending on the emissions laws there.

      If you make everything slip-on you're golden when emissions come around just swap back.

          I meant to comment on this... yeah, if you go full straight pipe from cat back, it's stupid loud and actually takes away from performance (at least it did on my Eta. I drove it like that for a couple days and hated my life. My system still has the cat and is straight until you get to the rear. Installed a Thrush Glasspack. Much better sound and the performance was back.

          My guess is that the M20 does need some backpressure, having a muffler there.

              Do that. Just don't weld it in or it's gonna be fun when smog time comes.

                You're not doing yourself any favors removing it tbh, performance or sound. It's going to be loud and sound raspy.
                I would remove the 2nd resonator or get a smaller muffler.
