The exhaust upgrades section covers the performance and alternative exhaust components for owners looking beyond the standard mild steel replacement system, whether the priority is long-term durability, improved performance, or both.
Stainless Steel Systems
Stainless steel exhaust systems manufactured in the UK from 309 and 401 grade stainless steel eliminate the regular replacement cycle that mild steel systems demand, backed by a lifetime warranty (non-transferable). They are available as complete systems or as individual sections, front pipe, centre silencer, rear silencer, and tail pipe, allowing owners to upgrade progressively or replace a single worn section. Systems are available for both chrome bumper and rubber bumper cars, with low-profile centre box options for improved ground clearance on cars with lowered suspension.
Performance Manifolds
Performance tubular exhaust manifolds replace the standard cast iron unit with a three-branch extractor design that promotes more efficient exhaust gas scavenging from the cylinder head. The improved extraction creates a leaner combustion environment, and richer carburettor needles should be fitted to compensate, ideally with the car set up on a rolling road after installation.
When fitting any aftermarket tubular manifold to an 18V thin-flange engine, check alignment with the inlet manifold carefully and contact MGOC Spares for fitting advice if required.
Manifold Wrap & Fixings
Manifold wrap in woven fibreglass tape retains heat within the exhaust manifold and downpipes, reducing underbonnet temperatures and improving exhaust gas velocity. Stainless steel manifold clamps and all associated fixings are available for a complete installation.
Tail Pipe Accessories
Polished stainless tail pipe extensions and tail pipe trims improve the visual finish at the rear of the car without requiring a full system replacement.
