06YarisRS's 2ZR-FE Swap 5-Door Hatchback (Automatic Transmission)

There used to be some good options for exhaust systems by RPM, but as you all know....they canned their 2zr support.

I would personally recommend finding a oem midpipe or at least the collector, then just have the rest of the system made to meet up with whatever performance muffler you have. I went with 2.25 all the way due to the overwhelming amount of complaints from people that tried 2.5. 1 catalyst and 1 resonator is all you need to pass smog and sound restrictions

You’re engine looks really nice, must be a unit someone took care of. Things should come together quickly now!

I strongly approve of your wiring work, looks completely oem. I soldered my wholle home-made harness with heat sharing also, and with all these years, and having it apart several more times... and racing! Don’t let anyone tell you solder is “brittle”.
