Automotive exhaust component that delivers a precise, leak-free replacement for worn flange gaskets, KIMISS Exhaust Gasket. Less noise and simpler DIY fitting bring immediate relief to motorists who want a practical repair. Is fitting a new gasket the most effective fix for a noisy or leaking exhaust?
⚡ At a Glance
- • Sealing Performance: Precision 2.5-inch 2-bolt flange fit with graphite-coated surface for tight sealing
- • Best for: DIY mechanics and garages needing a direct replacement for worn flange gaskets
- • Not ideal for: Exhaust systems that require custom or non-standard flange sizes and patterns
Precision 2.5-inch 2-bolt flange matches standard exhaust header and down pipe interfaces. Graphite-coated CNC-machined aluminium with zinc plating gives a lightweight, corrosion-resistant seal.
Leak-free sealing – thanks to precise 2.5-inch 2-bolt flange fit
Exact 2.5-inch inlet/outlet and matching 2-bolt pattern are manufactured to tight tolerances so the flange compresses evenly under bolt torque. Graphite-coated mating surfaces help conform to minor flange imperfections for a secure contact.
A reliable seal reduces exhaust leaks and associated noise. Correct torque during installation ensures a leak-free connection at the header to down pipe junction.
Lightweight construction – with CNC-machined graphite-coated aluminium
CNC machining delivers consistent thickness and flatness across the gasket, while a graphite coating improves heat resilience and sealing properties. The aluminium base keeps mass low compared with heavier metal alternatives.
Minimal added weight avoids impacting exhaust dynamics or vehicle performance. Consistent geometry simplifies alignment during a quick garage or roadside repair.
Corrosion resistance – with zinc-plated finish
A zinc-plated finish on the gasket surface gives anti-rust protection suited to high-temperature exhaust environments. The coating reduces surface corrosion that can otherwise lead to leaks over time.
Greater resistance to rust extends service life compared with untreated fittings. Fewer replacements are required in corrosive conditions such as salted roads or coastal areas.

❓ Frequently Asked Questions
Q: Will this fit my 2.5-inch exhaust with a 2-bolt flange?
A: Yes. The gasket is specified for 2.5-inch inlet/outlet with a 2-bolt flange, and user feedback confirms fitment on aftermarket exhausts when flange dimensions match.
Q: Will it stop exhaust leaks?
A: Properly fitted and tightened bolts combined with the graphite-coated sealing surface produce a leak-free seal, according to product descriptions and user experience.
Q: Is the gasket resistant to rust?
A: Yes. A zinc-plated finish is described as providing anti-rust characteristics to improve durability in corrosive conditions.
