Long Tube Headers 1988-1998 OBS Chevy GMC Truck K1500 K2500
Designed for 1988–1998 Chevy and GMC 4WD trucks with small-block V8 engines, these long tube headers feature 1-5/8″ primaries and 2-1/2″ collectors to optimize exhaust flow in mid-to-high RPM ranges. Best for enthusiasts seeking a straightforward bolt-on upgrade that improves throttle response and horsepower potential. The fully mandrel-bent 16-gauge stainless steel tubes and polished finish offer durability and corrosion resistance. Fitment note: compatible with select 1999–2000 Classic (carryover body style) trucks, but not the GMT800 or newer body styles.
- Best for: OBS truck owners seeking a reliable stainless upgrade with noticeable mid-to-high RPM gains.
- Caution: Confirm exact year/model fitment to avoid body-style conflicts with newer GMT800 generations.
LS Swap Long Tube Headers for 1979-2004 Ford Mustang
These long tube headers are engineered specifically for GM LS engine swaps into 1979–2004 Ford Mustang Fox Body and SN95 platforms. They accommodate many popular LS engines (4.8L, 5.3L, 5.7L LS1, 6.0L, 6.2L variants) and use 1-7/8″ mandrel-bent primary tubes with a 3″ collector. Best for: builders performing an LS swap who want improved exhaust scavenging and airflow, with compatibility focused on LS engines rather than factory Ford powerplants.
- Best for: LS swap projects in classic Mustangs seeking maximum LS breathing efficiency.
- Caution: Not designed for factory Ford engines; verify engine compatibility before purchase.
Exhaust Headers Kit For Chevy Corvette 1997-2004
This kit targets Corvette models from 1997–2004 with 5.7L V8 engines, featuring 1-7/8″ primary tubes and stainless construction. It offers a corrosion-resistant upgrade with a brand-new condition and no defects implied by listing. Best for: Corvette owners seeking a direct-fit, stainless long tube upgrade that supports improved exhaust flow.
- Best for: Corvette owners focusing on a corrosion-resistant, styled upgrade.
- Caution: Verify compatibility with your specific Corvette trim and exhaust routing to ensure a proper fit.
Merge Collector, Exhaust Pipe Expander, Long Tube Headers
This merge collector and expansion product is designed to fit a range of vehicles needing a smooth transition between headers and exhaust pipes. It uses stainless steel construction for reliability, anti-corrosion properties, and long-lasting service. Best for: projects requiring a compatible merge collector to optimize flow from multiple header primaries. Limitation: Fitment depends on pipe sizing and system geometry.
- Best for: Systems needing an effective merge point to reduce exhaust bottlenecks.
- Caution: Check the inlet/outlet sizes to confirm compatibility with your headers and piping.
Long Tube Headers for LS Swaps Black Aluminized
These LS swap long tube headers are coated with a black aluminized barrier, intended for LS-based swap applications in 1973–1987 C/K trucks and 1988–1991 square-body models (Blazer, Jimmy, Suburban). They feature 1-3/4″ primaries and 3″ merge collectors to boost torque and horsepower across the powerband. Best for: classic square-body builds that aim for a durable, high-flow LS swap header with protective coating.
- Best for: Square-body trucks upgrading to LS power with a protective finish.
- Caution: Not compatible with 1988–1998 OBS GMT400 or newer GMT bodies.
Buying Guide
Key considerations when selecting long tube headers for a Y-pipe or long-tube exhaust system include engine type, fitment, material, and overall flow design. First, identify your engine and intended use—OBS trucks benefit from stainless, durable headers with robust collectors, while LS swap projects prioritize primary diameter and collector length to optimize scavenging. Material matters: stainless steel resists corrosion and heat, while aluminized or coated headers offer cost benefits with good durability. Fitment is crucial; confirm model years, body style, and whether the system uses a 1-7/8″ or 1-3/4″ primary tube, as this affects flow and compatibility with your Y-pipe. Consider the collector diameter and the number of chambers or merges to ensure smooth flow into the exhaust system. For LS swap projects, verify that the headers are designed for LS engines rather than factory V8s in the platform. Also weigh installation practicality, such as availability of gasket kits (MLS gaskets recommended) and hardware compatibility. Finally, assess build quality: CNC-flanged surfaces, mandrel-bent tubes, and proper fitment sequences help prevent leaks and maximize efficiency.
FAQ
- What are long tube headers best for? They maximize exhaust flow and horsepower in mid-to-high RPM ranges, ideal for performance-oriented builds and LS swaps.
- Will these fit my 1988–1998 OBS truck? Yes, but verify year, engine size, and body style to ensure compatibility with the collector and flange design.
- Should I choose stainless or aluminized headers? Stainless offers superior corrosion resistance and longevity; aluminized headers are typically lower cost with good durability.
- Do I need MLS gaskets with these headers? For a high-performance seal and reliability, MLS gaskets are commonly recommended in performance installations.
- Are LS swap headers universal for all LS engines? Most LS swap headers are designed for specific LS configurations; verify engine family, displacement, and mounting pattern before purchase.
- Can I install headers with a Y-pipe? Yes, many long tube headers are compatible with Y-pipe configurations, but confirm the outlet size and collector alignment to ensure proper fit.
