Frequently Asked Questions

Will this Borla part fit my 2011-2012 Ford Mustang Shelby GT500?
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?
A cat-back, axle-back, tip, muffler, or post-catalyst component usually does not require tuning, but confirm the exact application, emissions configuration, oxygen-sensor locations, and local requirements before installation.

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. Professional installation is recommended.
