Product Details

The Borla 60521 cat-back exhaust system is engineered specifically for 2011-2013 Ford Mustang GT and GT500 models with 5.0L and 5.4L engines. This premium exhaust upgrade features split rear exits and is compatible with both automatic and manual transmissions.

Construction and Materials:

  • Constructed from 100% T-304 aircraft-grade stainless steel throughout
  • 2.75-inch diameter mandrel-bent tubing for optimized exhaust flow
  • Superior corrosion resistance compared to mild steel or coated alternatives
  • Precision TIG welding at all connection points for maximum durability

Complete System Includes:

  • Over-axle connection pipes
  • High-flow mufflers with Borla's patented acoustical tuning technology
  • Polished stainless steel exhaust tips
  • All necessary mounting hardware and clamps

Performance Benefits:

  • Increased horsepower and torque through reduced exhaust restriction
  • Aggressive performance sound without interior drone
  • Improved throttle response across the power band
  • Direct bolt-on installation using factory mounting locations

Borla backs this exhaust system with their industry-leading Million Mile Warranty, demonstrating their confidence in the quality and longevity of their stainless steel construction. The T-304 stainless steel material resists heat fatigue, corrosion from road salt and chemicals, and maintains structural integrity under extreme temperatures and vibration.

Easy, customer-friendly online shopping. I am satisfied.

Great site, fast ordering and processing. Found the mangaflow cat back I wanted for $180 cheaper then anywhere else. Can't wait to get my exhaust in

Best prices with fast shipping and order updates. Will buy from again.<br>

After shopping around and comparing prices Autoplicity had the best low price, and a great professional website. Ive referred family and friends and will definitely shop there again.

I ordered a Tokico shock and everything went great. Shipping took a few days and it came in good condition and at a great price!

good

I had the axle-backs for my 2013 Mustang GT, but want to get the other parts for the catback system. I purchased this over-axle (Borla 60521) and a JBA H-Pipe. I am VERY happy with my purchase. The shop that installed them and the H-Pipe only charged me $90 and said they fit together well. Autoplicity also had the lowest price on the internet and the lowest price on shipping. Recommended!
