They dyno-ed an engine with and without the catalyst hooked up on both regular and premium gas to check the gains of hp and torque. It seems better with it on regular gas. Might be affordable now, they're saying prices starting at $129.. I talked to someone from the company when it first came out and then it started at $300..
Now it might be worth it.
