Stainless Muffler Upgrade

The AFE POWER Stainless Muffler Upgrade Apollo GT Series is engineered for 2019–2025 GM GenV LT-series engines in fullsize trucks, delivering a refined exhaust solution that combines durability with refined sound characteristics. As a seasoned mechanic, you'll recognize this as a serious upgrade from factory restrictive systems—one designed for builders and enthusiasts who demand both performance and longevity. This center-inlet, offset-outlet configuration optimizes exhaust scavenging while fitting seamlessly into stock mounting locations, making it an ideal choice for daily drivers and weekend warriors alike.

Constructed from premium stainless steel in natural finish, the Apollo GT Series resists corrosion and heat degradation far better than aluminized alternatives, ensuring years of service without rust-through or acoustic deterioration. The 3-inch center inlet and 3-inch offset outlet design maintains velocity and backpressure balance across the RPM curve—critical for GenV LT power delivery. At 24.83 lbs, this muffler is substantial enough to absorb road vibration and drone while the internal baffle architecture tunes exhaust note without sacrificing flow. You'll notice cleaner welds and precision mandrel bends throughout, hallmarks of AFE's manufacturing that minimize restriction and turbulence.

Truck owners upgrading from stock systems will appreciate the noticeable torque response and improved throttle feel, especially under load or towing conditions. Installation requires no welding or cutting when paired with compatible mid-pipes and downpipes, though professional hangers and isolators prevent vibration transfer to the frame. This muffler pairs seamlessly with CFM or cat-back systems from AFE or complementary manufacturers, making it a trusted option for custom builds ranging from mild bolt-ons to aggressive tuning packages. Specify this for your 2019–2025 fullsize truck with GenV LT power and expect a measurable upgrade in both character and durability.
