Over the weekend my husband and I did a complete exhaust swap on my 2013 BRZ.
Parts list:
- FT-86 SpeedFactory Catted Header
- Motiv overpipe
- Motiv catted front pipe
- FT-86 SpeedFactory V1 resonated exhaust
This is essentially the Emissions Rage package, however I was supposed to receive the Invidia front pipe but got the Motiv instead. Overall I don't think that makes much of a difference, but when listening to sound clips keep that in mind just in case. I think it sounds exactly like their example videos, but ymmv.
I was honestly shocked by how easy this was. It took me two days at at a very relaxed pace to swap everything out.

All the new parts laid out
Rusty catback removed.
This car is only 3 years old, and the midpipe was so rusted to the muffler that we couldn't break it loose!
Header, front pipe, and MOTHERFUCKING overpipe removed.
That overpipe was the hardest part. We had to jack up the engine about 2" to get it out.
Out with the old, in with the new!
This is my very favorite header.
Because we're thoroughly ridiculous people, we loaded both headers in our ND and drove to the auto parts store to borrow an O2 sensor socket, thinking we could just do the swap there. The thing was so cheap they didn't have a loaner, so I just made a round trip cuddling my header for no reason.

Final Result
All seemed well when firing it up and revving it on the stands, but after bolting on the debris shields something wasn't right. There was a strange vibration. The next day I put the car up on ramps and did some investigating.
Header Wear Spot.
Sure enough, there was a tiny contact patch between the header and the metal debris shield.

I tried hammering and sanding first, but all I did was make my ears ring and end up with blisters, so I broke out the power tools. I started with a 1/2" drill bit, but that didn't quite eliminate the contact patch, so I used a 1" hole saw on it.
Success!
The contact patch is now completely eliminated, and there's no more vibration in the car.
Here is an exterior sound clip, followed by interior sound with the vibration issue:
