Install the magnaflow in place of OEM and add a Electric cutout. before magnaflow.
Install old resonator to the cutout side to tone it down some.

Win.

My car in highschool was setup like this.

Headers - Y pipe - electric cutout wide open or quiet muffler.

I mostly rolled around in stealth mode unless I wanted to scare the pants off of people.

I have it on my 07 HOE and let me tell you at the beginning i like it, now I’m getting bored, at lower RPM’s is loud as f!! but once you hit 70+ it will ride like a kitty, it helps gas mileage too once combined with air intake. Have fun with yours

Lol! I've never thought my was "loud as f" but maybe it's cuz I've had other legitimately loud rides and this one seems pretty subdued
