Cat-Back Exhaust

aFe Apollo GT Series 409SS Cat-Back — 2019–2026 Silverado / Sierra 1500 V6 4.3L / V8 5.3L

The Apollo GT is aFe's value-performance cat-back — 409 stainless instead of 304, but still mandrel-bent and built for real power gains. Available with polished or black tips; fits the 2019–2026 Silverado and Sierra 1500 across multiple engine options including the 4.3L V6. A strong choice when you want the upgrade without the premium price.

Fits the 2009–2019 1500 platform across multiple engine options. Unlike universal systems, this is built to the exact roofline and cab dimensions of your truck.

$1,394.99

Cat-Back Exhaust

Gibson Dual Extreme Cat-Back 2.25in — 2015–2022 Colorado / Canyon L4 2.5L / V6 3.6L

Gibson's Dual Extreme configuration places the exit tips on both sides of the rear bumper for an aggressive look that mid-size trucks rarely pull off from the factory. Built from aluminized steel for durability; fits the 2015–2022 Chevrolet Colorado and GMC Canyon in both 2.5L and 3.6L configurations. A real dual exit on a mid-sizer, not just a splitter.

$929.99

Cat-Back Exhaust

Gibson Dual Split Cat-Back 3in/2.25in — 2015–2018 Silverado / Sierra 1500 5.3L

Gibson's Dual Split system sends gases through a 3-inch main pipe that splits into two 2.25-inch rear exits — a design that keeps the system out of the tow path while still delivering dual-exit aesthetics.

DPF-Back Exhaust

aFe Atlas 5in DPF-Back Aluminized Steel — 2011–2016 Silverado 2500 HD Duramax LML 6.6L

Five-inch pipe diameter is a significant jump over the factory 4-inch — aluminized steel construction keeps the price in check while dramatically improving exhaust flow on the LML Duramax. Lower EGTs under tow, better turbo spool response, and a deep diesel rumble. Fits 2011–2016 Silverado 2500/3500 HD with the 6.6L LML Duramax.

Engineered specifically for the 2020–2026 Silverado 2500 and 3500 HD with the L5P Duramax. Flow improvements show up on the gauge: lower EGTs when loaded and better turbo response on the highway.

$808.99

DPF-Back Exhaust

aFe MACHForce XP 4in DPF-Back 304SS — 2007–2010 Silverado 2500 HD Duramax LMM 6.6L

304 stainless construction on a system designed for the LMM-era Duramax trucks — one of the most popular diesel platforms for performance builders. The four-inch pipe is a meaningful upgrade from the factory unit, and the mandrel bends keep velocity consistent through every turn. Fits 2007–2010 Silverado and Sierra 2500/3500 HD with the 6.6L LMM.

$500.99

DPF-Back Exhaust

Three-inch 304 stainless pipe, dual black tips, full DPF-back configuration for 100% emissions compliance. Fits 2020–2022 Silverado and Sierra 1500 with the LM2 diesel.

Gibson's Black Elite series uses T-304 stainless tips with a black ceramic coating that holds up to heat and road spray without flaking. Single-side exit configuration keeps the system clear of trailer hitches — important for HD trucks that actually work. Fits 2011–2016 GM 2500 and 3500 HD platforms with the 6.6L Duramax.

$683.99

Cat-Back Exhaust

Gibson Stainless Cat-Back — 2020–2026 Silverado / Sierra 2500–3500 HD Crew Cab 6.6L Gasser

Deeper sound than stock without being obnoxious for daily driving, and built from stainless steel to last through years of heavy use. Inventory in stock.

Shorty Headers

aFe Twisted Steel 1-3/4in 304SS Shorty Headers — 2021–2026 Silverado / Sierra 1500 V8 5.3L 6.2L

aFe's Twisted Steel design uses individual primary tubes that merge cleanly into a collector — reducing reversion and improving scavenging compared to the flat-face factory manifold. T-304 stainless, fully compatible with catalytic converters and downstream equipment. Fits 2021–2026 Silverado and Sierra 1500 with the V8 5.3L and 6.2L engines.

$1,195.99

Exhaust Manifold Kit

BD Diesel Exhaust Manifold Kit (Both Sides) — 1999–2013 Silverado / Sierra 1500 V8

The factory cast-iron manifolds on LS-era GM trucks are known for cracking and warping — BD's replacement kit covers both driver and passenger sides with high-quality iron castings that outflow and outlast the originals. Fits 1999–2013 Silverado and Sierra 1500, Suburban, Tahoe, Yukon, and Escalade with V8 LS engines. 18 in stock.

$797.99

Diesel Exhaust Manifold

BD Diesel Full Bore Exhaust Manifold — 2001–2010 Silverado / Sierra 2500–3500 HD Duramax 6.6L

The factory Duramax driver-side manifold has a pinch-down design that restricts exhaust flow and contributes to high EGTs — BD's Full Bore replaces it with a fully opened casting that restores exhaust balance across both banks. Fits 2001–2010 Silverado and Sierra 2500 HD and 3500 HD with the 6.6L Duramax (LB7 through LMM). CARB-compliant; 5 in stock.

$273.99

Exhaust Manifold

BD Diesel Passenger Side Exhaust Manifold — 2003–2013 Silverado / Sierra 1500 V8

Engineered for LS-series V8 applications across the 2003–2013 Silverado and Sierra 1500 platform, including Suburban, Tahoe, Yukon, Escalade, and H2 fitments. High-flow castings that outperform the factory piece out of the box. 17 in stock.

$367.99

Performance Headers

Gibson 16-Gauge Performance Header — 1999–2001 Silverado 1500 V8 4.8L (Ceramic Coated)

Gibson's performance headers use 16-gauge steel with a ceramic coating that protects against corrosion and retains heat inside the pipe — keeping exhaust velocity high and heat out of the engine bay. Unlike the shorty header category, Gibson's long-tube design is built for maximum displacement. Fits 1999–2001 Silverado 1500 with the 4.8L V8. A proven formula for older trucks that still deserve a real upgrade.

$1,086.99

Up Pipe / Connecting Pipe

BD Diesel LB7 Up Pipe Passenger Side — 2001–2004 Silverado / Sierra 2500–3500 HD Duramax 6.6L

The factory up-pipes on early LB7 Duramax trucks are known for cracking at the flex section — a problem that causes boost leaks and unmetered exhaust gas entering the cab. BD's replacement is built to outlast the original; thicker material at the flex joint, leak-tested before shipping. Fits 2001–2004 Silverado and Sierra 2500/3500 HD with the LB7 6.6L Duramax. Sold as passenger side; driver side available separately.

Borla's Touring tune is designed for the owner who wants T-304 stainless quality and measurable power gains without droning on the highway or waking the neighborhood. Cab-and-bed specific fitment for the 2019–2026 Silverado 1500 crew cab short bed — Borla calibrates the resonance chambers to eliminate interior resonance that plagues lesser systems. Uses factory fascia tips.

$1,822.99

Cat-Back Exhaust

Borla S-Type Cat-Back — 2019–2025 Silverado 1500 5.3L V8 CC/SB 147.4in WB

The S-Type sits between Touring and ATAK — aggressive enough to turn heads at idle, refined enough for the daily commute without becoming fatiguing. T-304 stainless, uses factory fascia tips. Fitment is specific to the 2019–2025 Silverado 1500 crew cab short bed 5.3L — Borla's cab-specific tuning means no drone at 65 mph, which is where most cat-back systems fail.

$1,759.99

Cat-Back Exhaust

Borla S-Type Cat-Back Black Chrome Tips — 2015–2022 Chevrolet Colorado

Borla's S-Type for the Colorado uses the same T-304 stainless and resonance-tuned architecture as their full-size truck systems — scaled for the mid-size platform. Black chrome tips give it a blacked-out look that works with both stock and lifted builds. Fits 2015–2022 Chevrolet Colorado across crew cab and extended cab configurations. One of the few cat-back systems that makes a Colorado sound like it deserves to.
