I remember back when I was Downpipe and Tune - I brought my car into Toyota because my headlight was dying (BMW problems) and they were giving me a hard time on covering the light because I "voided" the warranty with a "modification of the ECU" which had nothing to do with the light dying.
But...
Of course lots of factors, pure800 was being out worked, i individually heat wrapped my downpipe, dump tubes and manifold on the top, and I also now have a wide open hood, so that’s obviously why
