Install: Buschur Racing Catback & ETS High-Flow Cat
Just finished an install of the Buschur Racing Evo X S.S. Cross Flow Catback Exhaust & ETS High Flow Cat on a 2014 MR. Here are some pictures of the install for those who are thinking about doing a similar install. The install was really smooth. Thanks to Buschur as everything fit perfectly. I only have pictures of the completed install, but the steps below are straight forward.
Difficulty: Easy (if you have a lift. Could be more difficult if laying on your back as some of the bolts required some decent leverage.)
Tools required: Metric sockets, Ratchet & Open ended wrenches, plyers
Sizes: 10, 13, 14 & 17MM
Step 1:
Unbolt the oxygen sensor from the OEM cat (Tip: wait for this to cool completely. I didn't and it was extremely hard to loosen up)
Skip this step if only doing a catback.
Step 2:
Unbolt the nuts connecting the mid-pipe to the cat.
Step 3:
Remove the 14MM spring bolts connecting the mid-pipe to the muffler piping.
Step 4:
Remove the bolt supporting the mid-pipe on the hanger
Step 5:
Get a buddy to hold the rear muffler or use a jack stand. Unseat the muffler one side at a time and remove from the car. Transfer the rubber hangers to your new muffler hangers.
Step 6:
Install the new muffler to the left and right hangers.
Step 7:
Unbolt the OEM cat from the downpipe
Step 8:
Bolt in the high-flow cat using new gasket and bolts/nuts.
Step 9:
Re-install the oxygen sensor
Step 10:
Position the new mid-pipe in place by inserting it in to the new muffler, attach to hanger.
Step 11:
Bolt the mid-pipe to the cat. Make sure to use your new gaskets and nuts/bolts.
Step 12: Attach and tighten the exhaust straps. I had to use an impact wrench to get the strap tight enough to hold the exhaust joints securely.
Tighten all the bolts.

I'd say this video is an accurate depiction:
except the catback is slightly quieter with the stock cat. I believe the red Evo in the video above is running a high-flow cat or test pipe.
Overall, definitely louder than stock but in no way too compromised.
