How could you guys honestly believe that a device that is intentional installed to alters a vehicle's carbon emission levels, in violations federal emissions laws, would NOT void the manufacture's warranty?
Not trying to be a buzzkill but you whole drivetrain warranty is gone the second the dealer sees a different catalytic converter installed or the emissions system has been tampered with.
The manufacture of the sports cat should just be honest; you have to pay to play..
Do downpipes void warranty?
