Certified Automotive Experts Long Tube Headers for LS Swaps
These long tube headers are crafted from 304 stainless steel to resist heat and corrosion, offering durability for harsh driving conditions. The design features CNC-machined flanges and TIG-welded joints for a precise fit and lasting performance. Mandrel-bent tubes promote optimal exhaust flow to maximize horsepower and improve throttle response in LS swap projects, especially for classic Chevrolet and GMC trucks that require a reliable upgrade from stock manifolds.
Polished Stainless Long Tube Headers for Small Block Chevy GMC 1973-1987
Designed for classic 1973–1987 Chevy & GMC trucks, these long tube headers serve Small Block Chevy engines in C10, K10, C20, K20, C30, K30, Blazer, Suburban, and Jimmy platforms. They also fit Square Body models through 1991. The kit recommends using header spark plugs and heat shields for proper clearance, with specific plug and shield recommendations provided for a clean, reliable installation. The polished finish adds a clean, showroom-like look under the hood.
LS Swap Long Tube Headers for Ford Mustang Fox Body & SN95
Engineered specifically for GM LS engine swaps into 1979–2004 Ford Mustang platforms, these long tube headers accommodate popular LS engines such as 4.8L, 5.3L, 5.7L LS1, 6.0L, and 6.2L variants. The 1-7/8” mandrel-bent primaries are chosen to improve exhaust scavenging, enabling better airflow and potential horsepower gains for naturally aspirated or boosted LS swap builds. Not designed for factory Ford engines, these headers are ideal for dedicated swap projects needing robust primary tubes and an efficient collector design.
Exhaust Headers 2002–2013 Silverado/Sierra Suburban Tahoe
These direct-fit headers are designed for 2002–2013 GM full-size trucks and SUVs with 4.8L, 5.3L, 6.0L, or 6.2L LS-based V8 engines. They feature 1-5/8″ mandrel-bent primary tubes and a beveled Y-pipe flange on the right side to facilitate improved exhaust flow and easier piping alignment. The headers are constructed from 304 stainless steel, offering durability against heat, corrosion, and vibration fatigue while delivering enhanced throttle response and potential horsepower gains.
BBK Performance 1-3/4″ Long Tube Headers For Mustang GT
BBK headers are crafted for Mustang GT applications with a 1-3/4″ primary tube diameter and a polished finish. They are designed for high-flow performance and feature a vehicle-specific fit, ensuring compatibility with the model year and trim. The headers aim to improve exhaust scavenging and horsepower while maintaining a refined under-hood appearance with a durable finish.
Exhaust Headers 2002–2013 Silverado/Sierra (Right Side Y-Pipe)
This alternative variant for Silverado/Sierra trucks emphasizes a beveled Y-pipe flange on the right side, designed to improve exhaust routing and flow. Constructed from 304 stainless steel, the headers replace restrictive factory manifolds to boost horsepower and throttle response. The mandrel-bent primary tubes help preserve internal airflow through bends, supporting overall performance gains in LS-based engines.
Buying Guide: Key Considerations For Long Tube Headers With Y Pipe
- Engine compatibility: Verify engine type, displacement, and vehicle model year. LS swaps, small-block Chevy, and Ford Mustang applications each require specific primary diameters and flange configurations.
- Materials and finish: 304 stainless steel is common for durability and corrosion resistance. Polished finishes look premium but may require more maintenance to keep shine.
- Primary diameter and length: Larger primaries (1-7/8″ to 1-3/4″) improve flow but may demand aftermarket spark plugs or heat shields and careful packing in tight engine bays.
- Y-pipe design: Beveled or angled Y-pipe flanges can affect fitment and exhaust routing; ensure compatibility with factory mounts and braces.
- Fitment notes: Some headers require heat shields, specific spark plugs, or cable/coil clearance considerations. Check for notes about square body, OBS, or GMT-400 chassis compatibility if applicable.
- Installation considerations: Mandrel-bent tubes promote consistent flow but can require professional installation for optimal seal and gasket durability. Confirm whether additional gaskets, studs, and hardware are included.
- Performance expectations: Expect measurable gains in horsepower and torque, especially at higher RPMs. Real-world results vary with exhaust system pairing, cam setup, and tuning.
- Durability and warranties: Look for manufacturer warranties and documented durability, particularly for harsh climates and road conditions.
When selecting long tube headers with a Y-pipe, consider the vehicle’s intended use, the engine build, and the level of performance you want to achieve. The options above cover a range of classics, LS swaps, and modern GM applications, each offering distinct advantages in airflow, fit, and finish.
