About Borla

Borla Performance Industries was founded in 1978 and remains America's premium cat-back exhaust brand. Every Borla system is hand-built from T-304 austenitic stainless steel and backed by a million-mile warranty — the OE choice for Camaro ZL1, Mustang GT350, and Chevy Corvette.

Borla ProXS: Compact Power for Tight Spaces

When space is at a premium, the Borla ProXS Universal Muffler delivers uncompromising performance. Designed for tight chassis applications, this 2.0-inch inlet/outlet muffler provides the perfect balance of sound suppression and exhaust flow. Its compact footprint makes it an ideal solution for custom exhaust projects where larger mufflers simply won't fit.

Technical Specifications

  • Inlet/Outlet: 2.0-inch diameter for optimized flow
  • Material: Aircraft-grade T-304 austenitic stainless steel
  • Durability: 100% welded construction ensures structural integrity under high heat
  • Sound Control: Advanced continuous-filament fiber (CFF) technology
  • Versatility: Reversible design for easier installation in restricted areas

The Borla ProXS series is engineered to eliminate the restriction of factory mufflers, allowing your engine to breathe freely and produce more power. The high-temperature acoustic material ensures a deep, aggressive tone without the annoying drone often found in lesser aftermarket mufflers. With its natural mill finish, you can choose to leave it raw or polish it for a custom look. Trust GGCRACING to provide the high-performance parts you need to take your vehicle to the next level.
