Will any of these mods void the powertrain warranty?
1. 3" Long Tube Headers (replace stock headers) they don't make those
2. Upgraded Camshafts yes
3. Upgraded Cold Air Intake (K&N Cold Air Intake) no
4. Removal of rear catalytic converters (replaced with pipe) no
5. Removal of all catalytic converters (replaced with high flow catalytic converters) The high flow cats replace the 4 factory cats. So again, no.
6. Throttle body no
7. Professional Tune Yes. Bye bye powertrain warranty.
I do not know much about cars...yet. Thanks for helping out.
