Just a heads up Toyota TAS dept already tried to say my AWE track exhaust was causing my issue and that I need to return to stock to diagnose. (I am having multiple ISSUES). This dealership installed all the parts lol. Tread carefully my friend.It will throw a CEL but as long as youāre not tuning the ECU, I donāt see how they can deny warranty unless they can prove the catless downpipe caused the damage.

I truly believe, that Toyota is gonna throw darts at whatever they can push blame on. if I could go back to stock I would. Toyota used all my new OE parts and put them on my buyback. then took all my upgraded parts and put them on this new one.
Visit here, If you have any insight on a possible fix or idea as too the cause. I am all ears!What was the issue?
What are the cons of running a downpipe?As always pay to play. Yes, adding a downpipe will not void your warranty on issues unaffected by a downpipe (example electronics, etc).
But Toyota can deny warranty claims on powertrain related issues for adding a downpipe so you have to tread lightly.
Honestly if you are not going to add a tune I would just defer the downpipe for now. There are probably more cons to adding one without a tune than pros.
Potential warranty denial. If your not using a tune, potential for a CEL.What are the cons of running a downpipe?
Keep in mind if there is a full engine teardown/replacement Toyota corporate may want evidence and even send a tech onsite to confirm there was no supporting mods/tune that could have resulted in failure. At that point it's even out of the service managers hands.I asked the Supra tech at my local dealership about mods recently.
He said itās up to the service manager and Toyota. When we spoke about specific mods, he said cat back exhausts and cold air intakes were probably fine but commented I might run into trouble with a catless or high flow down pipe.
I was just curious since Iāve considered an exhaust but with 1 kid going into college + 1 needing new golf clubs , they donāt leave me with much money for mods. ?
Well said.Keep in mind if there is a full engine teardown/replacement Toyota corporate may want evidence and even send a tech onsite to confirm there was no supporting mods/tune that could have resulted in failure. At that point it's even out of the service managers hands.
