MPE + VRSF catted dp + exhaust flap mod

Might as well jump on all the exhaust threads. Ordered the car with MPE and took delivery last November, did the exhaust flap mod earlier this year and no lights or issues. Yesterday I finally installed a VRSF catted dp. What an awesome difference. Car has not been dyno'd or tracked so I don't have any quantitative info to post. Will take/post a video later today.

I went with the catted version bc I'm undecided on which tune to get and frankly I didn't want it "really" loud. The install was pretty easy and straight forward. Remove the air box, 1 v-band clamp, 1 mid-pipe clamp and 2 nuts. Took a couple hours max. I had to let the car cool down completely to get the V-band clamp off and I did have to use a pipe expander (borrowed from auto parts store) to get the dp to slide into the mid-pipe. The only gotcha was a clip above the 2 main bracket nuts that I didn't notice. Once I pried it up with a screwdriver the dp came right out. Plenty of room even with the O2 sensors installed.
