I have a 2021 GR Supra 3.0 and want a catless downpipe just for sound, I don’t plan on tuning the car for a few years. But the stock exhaust is very quiet and want to up grade it. I talked to a dealership and the tech said if I put a DP he’ll void it, meanwhile Toyota of America said they have to prove it was the issue of the engine issues. I know a downpipe won’t cause much issue but I had a WRX that motor spun a bearing out of warranty and lose over 10k from that so I’m very cautious. Any advice is welcome thanks.
