Warning.. tl;dr
Did the install this morning. Total of 1.5 hours start to finish including a jaunt around the neighborhood.
My advise to those without access to a lift is to back up or pull forward on ramps and jack up one side at a time. I opted to back on to them. I started driver's side by removing the rear nuts on both sides and then the front driver's side. You'll use 19mm sockets to remove the exhaust nuts with a 12" extension to the front. Breaker bars are handy unless you are gorilla strong. Once broken they come off by hand.
I was able to get to the front passenger side without jacking the other side, but it might be less effort by switching the jack. Then I removed the bracing. Six bolts, all 14mm. No issues there.
Make sure you pull off both sides before you attempt to install ... The exhaust moves enough to allow for the midpipe to slip off the studs up front then pivot sown. Again, take both sides off before installing.
Bolting back up is simple. Stock nuts up front (switching the jack makes it easier) and supplied nuts and bolts at the back. I reinstalled the brace and loosely attached it to the pipes to get them in position to align in the rear. Center by feel both left and right and up and down. The flanges are slightly different in shape but it's not hard to get them aligned. The driver's side was slightly a different angle but still seals perfectly.
17mm box wrench and socket tighten these, or you can double socket/wrench. Use your muscles here... Work each one in slowly. A torque wrench might be helpful but just make them as tight as humanly possible then use your breaker to move a bit more.
Great fit, only a bit of sound in the cabin. Virtually none with the windows open. I'll have to disconnect my jb4 to allow the car to adjust to give a fair assessment of butt Dyno feels. Then I'll log and send to them to fine tune.
Totally worth a couple hours of work... Those midpipes are tiny from the factory.
