Exhaust change and warrenty??

[Little Ernie]

If I change my exhaust system to a CAT back system to work on lowering my exhaust temperature will I void or give me a problem with any warrenty claims??
Thanks for any info. smile.gif

Generally no. There have been some issues with low backpressure and the setting of EGR codes in the LLY trucks, but those are the rare exceptions. Others may have more info on this issue.

Your warranty cannot be voided because of the mere existance of an aftermarket exhaust system. If it was a cause of EGR codes in an LLY however, that service visit may not be covered.
