Exhaust Flange Plates
Exhaust Flange Plates
Ensure a strong, leak-free connection in your exhaust system with our range of high-quality flange plates. Available in 2‑bolt, 3‑bolt, and 4‑bolt designs, these plates are custom-engineered for durability and precise alignment — ideal for manual or fabricated exhaust work.
Choose from mild steel or stainless options in common pipe sizes (2″, 2½″, 3″, 3½″, and 4″), with bolt-hole patterns suited for both standard and performance applications. Our 2‑bolt plates are perfect for simple fabrications, while 3‑bolt and 4‑bolt variants offer enhanced strength and sealing under high heat or vibration.
Pair flange plates with matching flange gaskets, bolts, studs & nuts, and exhaust clamps to complete your system with confidence.
Whether you're repairing OEM components or building a race header, our flange plate kits include everything you need — flanges, gaskets, bolts, and nuts — for a secure, twist-free joint. Expert advice and fast shipping Australia-wide.
