Metal Polish for Exhaust & Tail pipes
100ml

milltek

After years of being asked to come up with a solution from our dealers, race-teams and end-users, we have now solved a perennial problem for many conscientious owners; namely, how to refresh their stainless exhaust system to an 'as-new' condition when detailing the car. After several months of testing in all markets and weather conditions, we will soon be releasing a tailored metal polish that will render any stainless steel exhaust system or metal component ready for concours or show duty, with the minimum of effort. Perfect not only for keeping your Milltek system in tip-top condition, but also any other polished or chromed parts on your car (or bike!) too.

The polish has been developed by our R&D engineers in association with leading car care experts, Dodo Juice. The result is a high shine, mild-abrasive polish that can be used on all types of metal, including chrome. Sophisticated diminishing abrasives remove contaminants initially, then refine for a mirror finish while the chemical cleaning action helps dissolve fuel, oil and soot deposits. The final finishing touch is down to the use of an active sealing ingredient helps metal resist future tarnishing. The polish has been formulated to work well with any medium resistance, short-pile cloth and is an absolute doddle to apply or remove, making the art of restoring any metal surface the work of mere minutes.

100ml bottle with a FREE microfibre cloth, which should be more than enough for 20 intensive back boxes and tail trim cleans.

About Exhaust Gaskets

Exhaust Gaskets for Porsche | Precision Seal & Performance Reliability

Exhaust gaskets are crucial components in your Porsche’s exhaust system, ensuring a tight, leak-free seal between joints and flanges. They prevent exhaust gases from escaping, maintain correct back pressure, and protect nearby components from heat and harmful emissions.

At Design911, we supply a full range of exhaust gaskets designed for Porsche vehicles — from classic air-cooled 911s to high-performance modern models. Manufactured from high-temperature, corrosion-resistant materials, these gaskets deliver durability and a perfect seal under extreme conditions.

Whether you’re installing a new exhaust, replacing worn components, or upgrading for performance gains, our high-quality Porsche exhaust gaskets guarantee a reliable fit and long-lasting performance.

What Do Exhaust Gaskets Do?

Exhaust gaskets form airtight seals between the various components of the exhaust system, such as manifolds, headers, pipes, and catalytic converters. They play a vital role in maintaining system integrity, performance, and emissions control.

Core Functions:

  • Seals exhaust joints to prevent leaks and gas escape.
  • Maintains back pressure for efficient engine performance.
  • Reduces exhaust noise and vibration.
  • Protects against heat and gas damage.
  • Ensures compliance with emissions standards.

A properly fitted gasket ensures that exhaust gases are channelled efficiently through the system — essential for power, fuel economy, and emissions control.

Why Do Exhaust Gaskets Fail?

Over time, exhaust gaskets are subjected to extreme heat, pressure, and vibration, which can lead to wear or failure.

Common Causes of Failure Include:

  • Thermal expansion and contraction causing cracks or deformation.
  • Corrosion from moisture or road salt exposure.
  • Improper installation or over-tightening.
  • Aging and fatigue of gasket material.
  • Exhaust vibration leading to joint loosening.

When a gasket fails, you may notice hissing or tapping noises, a burning smell, or loss of engine performance. Exhaust leaks can also increase harmful emissions and damage surrounding components.

Why Replace Your Exhaust Gaskets?

Replacing worn or leaking exhaust gaskets is essential for maintaining your Porsche’s performance, efficiency, and emissions compliance.

Key Benefits:

  • Restores proper exhaust sealing and flow efficiency.
  • Reduces exhaust noise and prevents gas leaks.
  • Improves performance and throttle response.
  • Prevents damage to manifolds, sensors, and nearby parts.
  • Crafted from high-grade composite or metal-reinforced materials.
  • Exact-fit design for Porsche 911, Cayman, Boxster, Panamera, Macan and more.

Whether you’re rebuilding your exhaust system or performing routine maintenance, new gaskets ensure reliable sealing and long-term durability.

Highlights:

  • Precision-engineered exhaust gaskets for all Porsche models.
  • High-temperature, corrosion-resistant materials for durability.
  • Ensures a tight, leak-free exhaust seal.
  • Improves performance and emissions control.
  • Perfect fit for performance and restoration projects.
  • Essential for smooth, quiet, and efficient exhaust operation.
