1991–1995 Jeep Wrangler YJ 2.5L Exhaust Header Kit
This kit combines a tubular exhaust header, matching downpipe, and related connection hardware for exhaust system replacement, repair, and aftermarket supply. Four-port manifold construction matches the exhaust layout of the 2.5L four-cylinder engine. Polished stainless steel tubing provides a clean appearance and practical corrosion resistance for everyday use.
Included components cover the manifold gasket, flange sealing gaskets, exhaust pipe clamp, spring bolts, and other connection hardware, helping you source related parts together while reducing the time spent selecting and checking separate accessories. Main metal components can be processed and welded in-house. Material options, accessory combinations, product marking, labels, and packaging can be confirmed according to your order requirements. Exhaust headers, downpipes, and related individual components are also available for bulk supply.

Matched Component Design
Exhaust header and downpipe share a coordinated interface design, reducing fitment issues caused by mismatched flange angles, connection points, or pipe routing when sourced separately. For replacement projects, you can obtain the main front exhaust components as a matched set and continue using the same configuration for future repairs and replacements.
Durable Stainless Steel Construction
Polished stainless steel tubing performs reliably under long-term exposure to exhaust heat, condensation, and external corrosive conditions while maintaining a clean surface appearance. Tubular construction and stable welded joints accommodate repeated heating, cooling, and vehicle vibration, helping reduce the risk of corrosion, leakage, or cracking around connection areas over time. More consistent durability also gives you greater confidence in continued use and subsequent sales.
Precision Flange Connections
Yueding uses CNC-machined flanges to maintain accurate mounting profiles, bolt-hole positions, and sealing surfaces. Pipe joints completed by skilled technicians using TIG/MIG welding help create stable connections between the header, collector, and downpipe. Matching sealing gaskets, clamp, and spring bolts further support each connection point, helping you reduce repeated adjustments caused by interface deviations, unstable sealing, or mismatched accessories.
