Pypes Performance Exhaust DGU13S 2.5-Inch Stainless Steel Manifold Downpipes for 1978-1988 GM G-Body

Upgrade the exhaust system on your 1978-1988 GM G-Body with Pypes Performance Exhaust DGU13S intermediate manifold downpipes. Designed for small-block Chevy applications using stock three-bolt manifolds, this matched pair provides a direct, practical connection from the manifolds into the remainder of the exhaust system. The 2.5-inch pipe diameter supports efficient exhaust flow while maintaining compatibility with common G-Body exhaust configurations.
Constructed from stainless steel, these Pypes Performance Exhaust downpipes offer dependable corrosion resistance and long-term durability for street-driven vehicles, performance builds, and restoration projects. The natural stainless finish delivers a clean, functional appearance and can be left as-is or finished to match the rest of the exhaust system. Each pipe is formed for a vehicle-specific fit, helping simplify installation compared with universal exhaust tubing.
Designed specifically for 1978-1988 GM G-Body models, the DGU13S manifold downpipe pair is an excellent choice when replacing worn original components or building a reliable custom exhaust system around stock-style manifolds. Verify engine, manifold, and chassis compatibility before installation to ensure the correct fit. Professional installation is recommended, and all exhaust components should be properly supported and checked for adequate clearance from the vehicle body, wiring, fuel lines, and suspension components.
