Borla S-Type II Axle-Back Exhaust System (11917) - 2006-2013 Chevrolet Corvette C6 Z06 & ZR1 (Manual Transmission Only / Non-Valved)
Unleash the true acoustic potential of your high-performance machine with the Borla S-Type II Axle-Back Exhaust System. Custom-engineered specifically for 2006 to 2013 Chevrolet Corvette C6 Z06 and ZR1 platforms equipped with manual transmissions, this premium aftermarket upgrade balances a race-inspired soundtrack with sophisticated daily drivability. The S-Type II sound profile relies on advanced, vehicle-specific multi-core muffler technology designed to neutralize low-frequency cabin resonance. This means you enjoy a deep, rich, and aggressive muscle car growl under acceleration, without the exhausting interior drone during highway cruising. Constructed with a heavy-duty 3-inch inlet pipe diameter that transitions to dual 2-inch outlets, this free-flowing layout maximizes exhaust gas velocity and scavenging to unlock hidden horsepower, sharpen throttle response, and elevate driving excitement.
What sets the Borla 11917 apart is its streamlined, valve-delete configuration. It does NOT include mechanical NPP dual-mode exhaust valves, providing a direct and uninhibited pathway for spent exhaust gases. This system is a perfect fit whether your Corvette originally shipped with or without the factory valved exhaust. Fabricated entirely from premium, aircraft-grade T-304 austenitic stainless steel, this setup is vastly superior to budget aftermarket alternatives or factory T-400 series alloys (such as 409) to provide permanent protection against deep rust, moisture corrosion, and structural cracking. Precision computer numerical control (CNC) manufacturing and ultra-smooth mandrel bends ensure an accurate, line-to-line bolt-on fitment beneath your chassis. The center-exit rear section features a stunning set of quad 4.25-inch round, rolled angle-cut intercooled highly polished T-304 stainless steel tips that completely fill out the rear valence for an exotic, high-performance look. Best of all, Borla stands behind this system with their legendary Million-Mile Warranty.

- Fits **high-performance C6 widebody platforms only** (7.0L LS7 naturally aspirated and 6.2L LS9 supercharged). Does not fit base Corvette or Grand Sport models due to rear subframe and pipe diameter variances.
