Ams and AA are the only catted downpipes that don't throw a code. Had my AA installed for almost 13k miles and no issues. You should be perfectly fine not throwing a code.Hello,
I bought a 2022 supra and I would like to know if I install the air intake and AMS catted downpipe if I have an ECU code
Thank you!
Weird. 8k miles on my MAPerformance downpipe with no code. There are dozens of downpipes that also don't CEL. AA is _really_ good at that marketing though. Any downpipe with a GESI 400 cat is the exact same downpipe.Ams and AA are the only catted downpipes that don't throw a code.
Well damn, that's good though. There needs to be more that are equipped the 400 cat. Was basing it off when I was researching mine what everyone had said. Glad I know to recommend moreWeird. 8k miles on my MAPerformance downpipe with no code. There are dozens of downpipes that also don't CEL. AA is _really_ good at that marketing though.
