🔧 Exhaust Gasket Styles – How to Choose

Stainless Graphite Mesh (Tapered)
Best for most street and performance Harley applications. The tapered shape helps center the gasket in the exhaust port, while the graphite mesh provides excellent sealing as parts heat and cool. A great all-around choice for stock and mildly modified bikes.

Stainless Spiral Wound
Ideal for high-heat and high-vibration environments. The spiral-wound stainless design offers strong durability and consistent sealing, making it a solid option for riders who put a lot of miles on their bike or run performance exhaust systems.

Stainless Graphite Mesh – Race Style
Designed for high-performance and race applications where exhaust temps and pressures are elevated. These gaskets handle aggressive riding and repeated thermal cycling better than standard styles, making them a top choice for big-inch motors and track or stunt use.

👉 Choose .110" if everything lines up well and you don’t have sealing issues.
👉 Choose .240" if you’ve had leaks, ticking noises, or sealing problems with thinner gaskets.

Which One Should You Choose?

Daily rider / stock to mild performance: Tapered stainless graphite mesh
Heavy use / long rides / vibration-prone setups: Stainless spiral wound
High-output, race, or aggressive riding: Race-style stainless graphite mesh

If you’re unsure, the tapered stainless graphite mesh gasket is usually the safest and most versatile option.

🛠 Why Exhaust Port Gaskets Matter

Exhaust port gaskets seal the connection between your cylinder head and exhaust header. A worn or cracked gasket can lead to:

Exhaust leaks
Loss of engine performance
Louder exhaust noise
Reduced fuel efficiency

Installing a new Cometic exhaust gasket whenever you remove or install headers ensures the best sealing integrity and long-term reliability.

⚙️ Fitment & Compatibility

These Cometic exhaust port gaskets are used in many Harley-Davidson performance and stock exhaust applications. Fitment varies based on the flange style and port diameter — match the gasket part number to your exhaust/header system.
