Unleash the Rumble: The Ultimate Guide to Doug’s D380-C Side-Mount Headers for 63–82 Corvettes
Is there anything more iconic than a classic Corvette with side pipes?
If you are restoring or modding a 1963–1982 Small Block Corvette (C2 or C3), you know that the exhaust isn't just about airflow—it's about attitude. You want that visceral, ear-shattering rumble that announces your arrival before you’re even seen.
Enter the Doug’s Headers D380-C.
Known in the industry for precision engineering, Doug’s has created the definitive side-mount header for the classic SBC Corvette. Whether you are chasing show-winning chrome or raw horsepower, here is why the D380-C is the upgrade your Vette deserves.
Why Choose Doug's D380-C?
1. The "Show-Stopper" Chrome Finish
Let’s be honest: side pipes are a visual statement. The D380-C features a brilliant, show-quality chrome finish. These aren't just hidden under the chassis; they are a focal point of your car's exterior, designed to turn heads at every stoplight and car show.
2. Built for Flow (and Power)
Doug's didn't just design these to look pretty. They are engineered with 1-7/8" primary tubes and a massive 4.0" collector.
What this means for you: Your Small Block Chevy (SBC) can breathe. The larger tube diameter supports higher horsepower builds, letting that engine exhale freely for better throttle response and top-end power.
3. No Leaks, No Warp
One of the biggest headaches with aftermarket headers is the dreaded exhaust leak. Doug’s combats this with heavy-duty 3/8" flanges. These thick flanges resist warping under high heat, ensuring a tight seal against the cylinder head for "no-leak" performance.
