Our Cheeto is working on that ?Still not technically legal in California. Just an FYI for people.
First thing I confirmed when I saw this post. But tbh even if it was CARB compliant and legal, I'm curious what the decibel rating this downpipe with a stock exhaust produces because that opens up the whole "Modified Exhaust" can of worms. Welcome to CAStill not technically legal in California. Just an FYI for people.
Are the GESI cats in stock?Correct so now both options on that link (Active cats and GESI cats )are EPA approved.
YesI just ordered this a couple days ago: https://x-ph.com/active-autowerke-aa-bmw-supra-b58-catted-downpipe-fits-f-g-chassis/
Is it any different than https://x-ph.com/active-autowerke-supra-mkv-a90-a91-3-0-signature-catted-downpipe-11-564/?
Are they the same downpipe?
its the same cat so it should apply to the previous ones as well but I'm double checking with active and should have an answer very soonDoes this only apply to new ones?
YesAre the GESI cats in stock?
That's really what keeps me from pulling the trigger.I keep reading that there have been CELs with the new cat and AA either doesn't respond or blames the o2 sensors
What's up with that no CEL guarantee?
