This can be a real contender to the AA and AMS catted downpipes if it truly does not throw a CEL... also the big question how much is it???

Per MST, the cat comes with a 2-year warranty, if you get a CEL during that time, they will replace the downpipe for free.

Eh yes and no, I think the lack of epa legal could be a turn off, if it was a lot cheaper then AA but it is the same price, and one is fully legal in 49 states...

I’m interested, are there sound clips or performance information/testing?

No sound clip is available yet.

I will flow similarly to other catted downpipe options on the market. The advantage of getting MST over other brands is that it does not trigger the check engine light.

MST claims - Large diameter design gives you the same efficiency as straight pipes.

Are they stating that this has the same flow as a catless DP?

Yeah, we wanna see them flow-bench numbers!

From all the data posted, the gains are the same with high-quality catted downpipes & catless on the stock turbo.

I only see a significant difference in power when running larger turbos.

Is this a plug and play fitment for an unmodified 2023 Supra M/T? I don't want to add any harnesses or additional brackets or modify any existing hardware on the car to make this fit.

Get the pricing below your current gold standard competitors and hopefully two things will happen.

1. They fly off the shelves.
2. Develop a good reputation within the community to be the new gold standard.

Sell it below $1k, and I would definitely get one.
