Exhaust Header
Sport Manifold Exhaust Header for Chevy GMC 88-97 K1500 K2500 Pickup 5.0L 5.7L
A 1-3/4 inch shorty exhaust header built for the 1988-1997 Chevrolet and GMC K1500 and K2500 pickup trucks with 5.0L and 5.7L V8 engines. It replaces the factory exhaust manifold with a single piece header that bolts on without welding. Fitment is year and model specific and does not cover 4x4 models with the 4.3L V6 engine.
What You Get
Key Benefits
- 1-3/4 inch primaries improve exhaust flow and reduce back pressure compared to the factory manifold
- Bolt-on replacement geometry follows the factory routing and fits stock hangers
Why Buyers Switch
Problems It Solves
- Factory exhaust manifolds crack at the port welds after repeated heat cycling
- Mild steel aftermarket headers rust at the flange and fail within a few seasons
- Universal headers require cutting and welding, which adds shop labour and risk
- Poorly machined flanges leak at the manifold joint and cause vacuum issues
Where It Is Used
Application Scenarios
- Performance shops upgrading older GM trucks for better throttle response and engine breathing
- Distributors stocking vehicle-specific headers for the 1988-1997 K series pickup market
- Online sellers needing a photographed, fitment-verified part with a clean product listing
- Restoration workshops replacing corroded factory manifolds on classic trucks

Comparison
Compared With The Alternatives
| Factory exhaust manifold | The stock manifold is heavier and restricts flow with narrow ports; this header opens the primaries to 1-3/4 inch for better engine breathing |
|---|---|
| Universal cut-to-fit header | A universal header requires cutting and welding; this one bolts on without modification |
Installation
Use Guide
- Confirm the truck is a 1988-1997 K1500 or K2500 pickup with 5.0L or 5.7L V8 and not a 4x4 with the 4.3L V6
- Let the engine cool fully before removing the factory manifold
- Replace the manifold gasket rather than reusing the old one
- Torque the flange bolts evenly in a cross pattern to keep the sealing face flat
- Recheck flange torque after the first heat cycle
