Frequently Asked Questions

Will this Borla part fit my 2015-2020 Chevrolet Suburban LS?
That application is listed, but confirm the engine, drivetrain, body or cab style, wheelbase, factory exhaust layout, tip opening, and every Borla application note before ordering.

Will this change require an engine tune?

What should I inspect before installation?
Check the shipping carton and components against the exact part number, then inspect clamps, hangers, gaskets, mating flanges, clearances, tip alignment, and required reused factory hardware before removing the original exhaust.

Installation Instructions

Follow the current Borla instructions and vehicle service information for this exact part number. Let the exhaust cool, support the vehicle safely, compare all parts before removal, protect sensors and wiring, use the specified clamps and torque values, align all joints and tips without preload, confirm body and suspension clearance, check for leaks, and retorque after the first heat cycles.
