Product Details

The Borla 11751 S-Type Axle-Back Exhaust System delivers impressive performance gains and aggressive exhaust tone for 2005-2009 Ford Mustang V6 applications. This professionally engineered system produces double-digit horsepower increases while maintaining zero highway drone, making it ideal for daily driving with enhanced performance.

Performance and Flow:

  • Flows an impressive 724 CFM—a 346 CFM increase over factory exhaust
  • 2.5-inch CNC mandrel-bent tubing maximizes exhaust velocity and power
  • Patented straight-through multi-core muffler technology unleashes hidden horsepower
  • Improves throttle response, acceleration, and fuel economy

Construction and Quality:

  • Manufactured from aircraft-grade T-304 austenitic stainless steel
  • Superior corrosion and rust resistance compared to aluminized or 409 steel
  • Lightweight, durable construction reduces weight over factory exhaust
  • 4-inch round, rolled, angle-cut polished tip with Borla embossing

Installation and Fitment:

  • Direct bolt-on installation using factory hangers and mounting points
  • Most installations completed in under one hour with no cutting required
  • Uses original rubber isolators for secure, vibration-free mounting
  • Includes all necessary hardware and detailed instructions

The S-Type sound level delivers an aggressive, performance-oriented exhaust note that's louder than Borla's Touring series but remains perfectly livable for daily driving. This system is backed by Borla's industry-leading Million-Mile Warranty, demonstrating their confidence in the quality and durability of their products.

The floor mats I purchased for my car work like a dream. They were just as described in the listing. The shipping was also pretty quick. I just wish the price was about $20 cheaper. Other than that I was completely satisfied.

Bought a Husky trunk liner for my Civic. Autoplicity had the lowest price I could find, plus I received it in two days. Only problem I had was that their website had a problem with the part fit check. Although the description and part number was for the 2012 Civic, the part check said it would not fit. Had to wait until Monday to call customer service to verify that it would fit before I ordered. Would definitely order from Autoplicity again.

smooth and easy

After searching online I found the best price with free shipping here. Fast shipping and easy installation of my product.

Recieved item in great shape. Could be a little faster with shipping, but over all, I had a good pleasant experience. Thank you.

Smooth transaction! Best price on the floor liner I was looking for, shipped promptly with tracking info provided, exactly as advertised. THANKS!!
