Borla 11951BC S-Type Axle-Back Exhaust System with Active Valves

The Borla 11951BC is a 2.5-inch diameter axle-back exhaust system designed specifically for the 5.0L Mustang GT equipped with Active Valve Performance Exhaust. It fits both coupe and convertible models, including Bullitt editions.

S-Type Sound Signature:

This system delivers the classic S-Type sound with no drone inside the vehicle. The S-Type system produces a moderate sound level that falls between the mild Touring exhaust and the wild ATAK systems, maintaining a comfortable cruising volume on the highway and opening up with an aggressive sound when you accelerate.

Premium Construction:

• Built from premium T-304 stainless steel, superior to T-400 series knockoffs
• Ultra-smooth mandrel bends ensure maximum flow and power
• Features dual 4-inch round black chrome on T-304 stainless steel tips on each muffler assembly
• Straight-through and patented multi-core technology designed to unleash hidden horsepower
• Precision computer-controlled CNC manufacturing ensures an accurate fit

Installation Notes:

Installation requires you to transfer over your factory active exhaust solenoids, which easily disconnect from your OE exhaust and install on the new Borla system. Once installed, all drive and exhaust modes will be retained. By adding Borla X-Pipe with Mid-Pipes part number 60705, you can create a complete Cat-Back system.

Tip Care:

Using Borla Stainless Steel Polish p#21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth.
