Replaced it with the Magnaflow, third cat was modded in a way if I want I could remove on my own and replace with 2.5 pipe and clamps. Shops anymore don't like messing with emissions, so they were nice and worked with me. If I decide to remove it again. If I had purchased non catted PPE DPs they wouldn't even have installed them. From front is PPE catted DPs, pipes on third cat are moved up to 2.5, Magnaflow resonator, MRT axle-back with Helmholtz resonators. Alot of money spent on exhaust, but heck everything for this platform is alot of money spent .
I tried this setup, but ended up pulling the magnaflow out and putting the stock resonator back in, it helped quite a bit with the raspy sounds. When I looked through the the stock resonator it didn't look like there was any significant air flow restrictions, the stock mufflers on the other hand, looked to be a pretty good choke point.
