Description

Replacing your exhaust can be a nightmare if the studs snap or the nuts seize solid from heat and weather exposure. This “Maintenance Reality” is why we created this bespoke kit. We use superior full-copper crush gaskets that offer better heat transfer than OEM composite ones, combined with UK-made, weather-resistant stainless steel and brass hardware. This guarantees a perfect seal and hassle-free future maintenance.

💎 Performance with the “Shiny” Look!

A perfect exhaust seal restores lost torque and ensures the clean lines of your exhaust headers aren’t ruined by rusty hardware.

Full Copper Rings High temp crush-seal technology for zero leaks.	Stainless Hardware Tall nuts won’t rust or seize onto the studs.
Brass Washers Rust-proof longevity and durability.	OEM Spec Studs Grade 8.8/10.9 steel for secure mounting.

🔧 Install Tips

Clean Flanges: Ensure the cylinder head mounting surface is perfectly clean of old gasket material before fitting the new copper rings.
Torque Evenly: Hand-tighten all nuts first, then use a torque wrench in a criss-cross pattern to crush the gasket evenly and prevent leaks.
Anti-Seize is Key: Always use a high-quality anti-seize lubricant on the studs and nuts to ease future removal.
