safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.

exhaust gases including harmful carbon
monoxide (CO) may collect and enter
the vehicle. This may lead to death or a
serious health hazard.
