Tunit diesel performance chip with Redback 2.5" Hi-Flow exhaust system fitted

No, Nissan isn't too fussed about exhaust systems.

Chips could be a different story, but I am yet to see evidence of a warranty claim being knocked back due to the presence of a chip.

Having said that, I think it's wise to play on the safe side, and remove the wiring and chip for dealer servicing.
