Borla 99-04 Ford Mustang 4.6L V8 Catback Exhaust

For your 1999-2004 Ford Mustang GT or Mach 1 with the 4.6L V8, Borla offers their S-Type Cat-Back™ exhaust system. This system replaces the factory exhaust from the catalytic converter back, giving you a more aggressive sound and improved exhaust flow. Borla has been a trusted name in Mustang performance for decades, working with top tuners and racing teams to develop their exhaust systems.

The S-Type system is built from aerospace-grade T-304 stainless steel, which is a stronger and more corrosion-resistant material than other stainless steel grades or aluminized steel. This means it's built to last. Borla uses ultra-smooth mandrel bends throughout the 2.5" diameter tubing to ensure maximum exhaust velocity and airflow, which translates to noticeable power gains. The unique muffler design is engineered to cancel out unwanted high-frequency sound waves, so you get an aggressive, powerful sound without annoying drone inside the cabin. This system features a pair of single 4" round, bright chrome tips for a sharp look.

This is a bolt-on installation, meaning no welding is required. Borla backs this system with their Million-Mile Warranty, reflecting the confidence they have in the durability and performance of their products. This system is designed to maximize performance from other aftermarket enhancements you might have on your Mustang.
