AFE Exhaust Cat Back - Mach Force-Xp 304SS System for C8 Corvette (Part: 49-34124-C)
If you want to unlock the true mid-engine sound profile of your LT2 V8 without triggering error codes or dealing with massive cabin drone, swapping out the stock piping for the AFE Exhaust Cat Back Mach Force-Xp system is the ultimate route. This premium kit (Manufacturer Part Number: 49-34124-C) features a full 3-inch to 2-1/2-inch mandrel-bent 304 stainless steel layout designed specifically for the 2020+ Chevrolet Corvette C8. It provides a direct, bolt-on replacement that increases exhaust flow, dropping weight while adding a deep, aggressive exhaust note under acceleration.What sets this AFE Exhaust Cat Back setup apart from generic track systems is its ability to retain your factory exhaust valve architecture. The system is engineered with computer-aided precision to house your stock Active Fuel Management (AFM) and Dual-Mode (NPP) electronic valve motors. Inside the high-flow, high-temperature metallic black muffler is an integrated X-pipe section that balances shifting exhaust pulses. This balances the tone perfectly and keeps your cockpit civilized while cruising, then opens up wide to unleash an extra 9 horsepower and 10 lb-ft of torque when you step on the gas.Features and Benefits
- Retains AFM & NPP Valve Electronics: Built with laser-precise mounting plates that accommodate your factory active valve actuators, allowing full control over your sound modes directly from your Corvette's touchscreen dashboard.
- Integrated Internal X-Pipe: The specialized high-flow muffler features an internal X-pipe crossover that evenly balances exhaust pulses. This maximizes exhaust scavenging and eliminates the harsh cabin drone common in mid-engine setups.
- Brushed 304 Stainless Steel Construction: Built entirely from 3-inch stepping down to 2-1/2-inch mandrel-bent 304 stainless steel tubing. This provides maximum exhaust velocity along with lifelong protection against corrosion and heat cycling.
- Quad Carbon Fiber Tips: The system finishes with a massive set of clamp-on, quad 4-1/2-inch real carbon fiber tips over polished stainless steel housings, giving the rear diffuser an aggressive, high-end look.
- Heavy-Duty Interlock Flex Pipes: Uses premium flex sections with structural, internal interlock liners to handle the natural engine twist and high vibration levels of hard driving without cracking.
- 100% TIG-Welded Durability: Fully TIG-welded by hand to ensure immense weld strength, perfect alignment along stock hangers, and leak-free performance over time.

FAQ
Will installing this AFE Exhaust Cat Back system cause a Check Engine Light?
No, it will not, provided you reuse your factory valve motors. The AFE Exhaust Cat Back (Part: 49-34124-C) includes physical mounting provisions for both your AFM and NPP electric valve actuators. Once your factory motors are bolted down onto the aFe brackets and plugged into the stock wiring harness, the car's computer operates them normally without throwing fault codes.Do I need to cut or weld my factory mid-pipes to install this kit?
No cutting or welding is required. This is a direct, 100% bolt-on assembly that utilizes your stock-style flanges and factory rubber isolation hangers. It connects right where the factory catalytic converters drop down, allowing you to return the car to stock later if you ever need to.What is the finish on the muffler body itself?
The main high-flow muffler casing features a high-temperature metallic black coating. This specialized finish is applied to prevent rust and discoloration from intense exhaust heat while remaining completely hidden away cleanly underneath your C8's rear bumper assembly.Related products
