Borla Cat-Back Exhaust System - S-Type

The Borla S-Type Cat-Back Exhaust System is the go-to choice for performance enthusiasts who want a bold, aggressive exhaust note with real, measurable performance gains — and the confidence of the industry's strongest warranty behind every mile. As a true cat-back system, it replaces the entire factory exhaust from the catalytic converters rearward, delivering one of the most impactful bolt-on upgrades available for cars, trucks, and SUVs.

Patented Performance Technology:

• Straight-through and multi-core muffler design — Borla's patented internal architecture maximizes exhaust flow and velocity to unlock hidden horsepower and torque
• Increased exhaust velocity — Simultaneously improves power output, throttle response, and fuel efficiency
• Engine-specific muffler tuning — Every system is engineered, tested, and dyno-optimized for a specific vehicle platform, never a universal compromise
• Ultra-smooth mandrel-bent tubing — Consistent bends eliminate the flow restrictions found in conventional crush-bent exhaust systems
• Precision CNC manufacturing — Computer-controlled fabrication ensures accurate fitment using OEM hanger locations for a clean, factory-style installation

Aircraft-Quality T-304 Stainless Steel Construction:

• Fabricated from premium T-304 austenitic stainless steel — a superior grade compared to the T-400 series materials commonly used by competing brands
• Higher carbon and nickel content delivers exceptional long-term resistance to rust, corrosion, and extreme heat cycling
• Handcrafted in the USA — designed at Borla's R&D facility in Oxnard, California and manufactured at their 100-acre production complex in Johnson City, Tennessee

The S-Type Sound Profile:

• Produces Borla's signature aggressive S-Type tone — noticeably louder and more assertive than the mild-mannered Borla Touring series, yet more refined and controlled than the race-inspired ATAK

• Engineered to minimize interior drone at highway cruising speeds, making it a practical choice for daily-driven vehicles
