Apollo GT Series 409 Sta inless Steel Muffler Del

The AFE POWER Apollo GT Series 409 Stainless Steel Muffler Delete Kit is a direct bolt-on exhaust modification designed for GM fullsize trucks (2019–2020 model years). This 3-inch diameter muffler delete system replaces the factory muffler with straight-through piping, delivering increased exhaust flow and a more aggressive exhaust tone without requiring extensive welding or fabrication work. The natural stainless steel construction provides corrosion resistance for long-term durability under harsh driving conditions.

The 3-inch diameter piping matches most modern truck exhaust systems, ensuring proper fit and scavenging efficiency. Stainless steel 409 grade is the industry standard for exhaust applications—it balances thermal resistance, corrosion protection, and cost-effectiveness compared to higher-grade stainless alloys. The kit weighs 5.88 pounds and measures 30.8 inches in length, designed to fit within the factory exhaust routing on compatible GM platforms. Direct installation eliminates the factory muffler's acoustic and backpressure characteristics, resulting in measurable gains in exhaust velocity and system efficiency.

This muffler delete is intended for truck owners seeking enhanced exhaust tone and flow on new-generation GM fullsize platforms (2019–2020). It's ideal for those who've already invested in intake or turbo modifications and want to complete their exhaust system upgrade without the expense of a full cat-back kit. AFE POWER muffler delete kits are engineered for OEM-quality fitment, requiring no modifications to fuel mapping or engine tuning. The natural stainless finish resists oxidation from moisture and salt exposure, making it suitable for both highway and off-road use.
