Best Royal Exhaust in 2026

A sudden, persistent check engine light often signals that your exhaust system is failing, making this Royal Exhaust rear catalytic converter pipe a vital replacement for 2003 through 2007 Nissan Murano 3.5L models. This aftermarket component includes a built-in flex for improved installation and fitment, though it won't look exactly like your original factory part. It is crucial to note that this is a non-CARB compliant piece, meaning it is strictly prohibited for use in California or New York due to emission standards. Because it is designed to address P0420 and P0430 fault codes, you should ensure any underlying engine performance issues are resolved first to prevent the light from returning. Remember that federal law requires this to be installed by a certified professional rather than a private individual.

While it won't look exactly like the factory stock part, it serves its primary function of addressing emissions issues. You must keep in mind that this specific model is not legal for use in California or New York due to non-CARB compliance.
