very nice , i love that video

Nice video

I noticed one thing about this Evo X they built. They don't list any type of replacement for the OEM catalytic converter. If they were able to accomplish this with the OEM cat still in place...that's pretty impressive.

Has anyone read anywhere if they did replace the cat?

I don't think I read it directly, but they wanted this car to still pass CA inspection after modifications. Any HFC or test pipe would fail it instantly. I'm pretty sure they kept the cat.

That was my assumption as well since I also didn't see anything saying they replaced the cat and I remember the part about wanting the car to remain street legal and able to pass Cali emissions
