Product Description Upgrade your 1988-1998 Chevy or GMC 4WD OBS truck or SUV with Certified Automotive Experts Metallic Ceramic Coated Long Tube Exhaust Headers. Designed for K1500 and K2500 applications equipped with 5.0L 305 or 5.7L 350 small block V8 engines, these headers are engineered to improve exhaust flow, throttle response, and overall performance while delivering a durable high-temperature ceramic coated finish built for demanding use. Featuring mandrel-bent steel tubing with 1-5/8 inch primary tubes and 2-1/2 inch collectors, these headers are optimized for improved scavenging and stronger mid to high RPM power characteristics. Reinforced TIG-welded construction and CNC laser-cut 5/16 inch flanges help provide long-term durability, strength, and sealing performance under high heat conditions. The metallic ceramic coating helps manage underhood heat while providing a clean premium appearance suited for both street-driven and off-road OBS truck builds. These long tube headers are designed specifically for 1988-1998 Chevy GMC 4WD OBS platform vehicles including K1500, K2500, Tahoe, Yukon, Suburban, and Blazer models equipped with 305 or 350 V8 engines. Certain 1999-2000 Classic carryover body style models are also compatible, though these headers are not intended for 1999 and newer new body style GMT800 trucks or SUVs. As with most long tube header systems, installation may require minor modification, repositioning, or clearancing depending on vehicle setup and factory equipment. Common areas that may require adjustment include factory column shift linkage, steering components, and power steering bracket clearance. These considerations are common with performance long tube header installations and are not considered defects. Designed for enthusiasts seeking improved exhaust flow, classic OBS truck styling, and durable ceramic coated construction, these headers provide a strong foundation for street, towing, off-road, and performance-oriented builds. Professional installation is recommended for best results.
