it's easily reversible if you have any negative side effects, though may store fault codes in the ECU.

Back pressure reduction reduces torque below, what, 3k rpm. Increases sound, true. Easiest exhaust mod by far. Leaves flap that routes all exhaust to the right pipe open so it flows through both pipes.

Just crimp the line at the driver side actuator with wire tie. Easier, and much easier to reverse.

Naturally, you do this at your own risk. I didn't like the effect and sound was iffy enough that I went back to stock.
