3 Bolt Exhaust Flanges

3‑Bolt Exhaust Flange Plates

Upgrade to a more secure exhaust connection with our 3‑bolt flange plates, which offer superior sealing strength and durability over standard 2‑bolt styles. These are ideal for high-performance or turbocharged systems that endure higher pressure and heat.

Commonly used in performance headers and connection points, 3‑bolt flanges provide enhanced clamping force and reduced risk of warping—perfect for DIY fabrication and heavy-duty installations. Choose grades including mild steel or corrosion-resistant stainless, with sizes from 2″ to 4″ and precision bolt hole patterns for easy alignment.

Pair these flange plates with matching flange gaskets to ensure leak-free sealing. Complete your setup using bolts, studs & nuts and our full exhaust clamp range.

Need a more compact or simpler solution? Check out our alternatives: 2‑bolt flanges or heavy-duty 4‑bolt flanges, depending on your build requirements.
