Optimize Exhaust Flow with Borla ProXS

The Borla ProXS 3in Universal Oval Muffler is the ideal solution for custom exhaust builds requiring a larger diameter for increased airflow. Measuring 4in x 9-1/2in x 14in, this muffler fits a wide range of applications while providing the legendary Borla sound profile. Its free-flow internal design minimizes backpressure, allowing your engine to breathe easier and perform at its peak.

Why Choose Borla ProXS?

  • Advanced Sound Control: Utilizes high-temperature continuous-filament fiber (CFF) to manage exhaust notes effectively.
  • Superior Material: Crafted from T-304 austenitic stainless steel to prevent rust and ensure structural longevity.
  • Versatile Fitment: Designed with a center/offset configuration for easier routing in tight undercarriages.
  • Robust Construction: 100% welded seams provide maximum strength under high-heat conditions.

This muffler is perfect for those looking to upgrade their exhaust system for better throttle response and a deeper, more refined tone. The reversible design offers added flexibility during the installation process, making it a favorite for custom fabricators. Find your next performance upgrade for your vehicle at GGCRACING.
