With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.

Now also includes our SR065D drill guide.

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 Fitting Kits

Exhaust Fitting Kits for Porsche | Complete Installation & Repair Solutions

The exhaust fitting kit is an essential component of any exhaust installation, replacement, or upgrade. It ensures that all joints, clamps, seals, and brackets in your Porsche’s exhaust system are correctly aligned and securely fastened, preventing leaks and maintaining proper exhaust flow.

At Design911, we supply a wide range of exhaust fitting kits designed to match Porsche exhaust systems with manufacturer-level accuracy. Each kit includes high-quality gaskets, clamps, bolts, nuts, seals, and mounting hardware, ensuring a professional, leak-free fit — whether you’re restoring a classic 911 or maintaining a modern performance model.

Our fitting kits are manufactured to exact tolerances from corrosion-resistant materials, guaranteeing a long-lasting seal and reliable performance under high-temperature, high-pressure conditions.

What Do Exhaust Fitting Kits Do?

An exhaust fitting kit provides the components required to properly install, secure, or replace sections of your Porsche’s exhaust system. These parts ensure stability, prevent vibration, and maintain airtight joints for optimum exhaust efficiency.

Core Functions:

  • Seals exhaust joints to prevent gas leaks and noise.
  • Secures exhaust components such as pipes, silencers, and catalytic converters.
  • Reduces vibration and movement caused by engine motion.
  • Ensures proper exhaust alignment for optimal flow and pressure balance.
  • Maintains performance and compliance with emissions standards.

Using a dedicated Porsche exhaust fitting kit ensures your system functions exactly as intended — improving both performance and reliability.

Why Do Exhaust Fitting Components Fail?

Due to constant exposure to heat, vibration, and corrosive exhaust gases, fitting components are prone to wear over time.

Common Causes of Failure Include:

  • Rust and corrosion from road salt or moisture.
  • Thermal fatigue from repeated heating and cooling cycles.
  • Loose fittings causing leaks or rattles.
  • Worn seals or gaskets leading to reduced exhaust pressure.
  • Cracked or weakened clamps and bolts from prolonged vibration.

A failing fitting kit can lead to loud exhaust noise, loss of performance, emission leaks, or even component misalignment. Replacing these parts is essential for safety, efficiency, and sound quality.

Why Replace or Upgrade Your Exhaust Fitting Kit?

Replacing old or damaged fitting components with precision-engineered replacements ensures your Porsche’s exhaust system performs at its best.

Key Benefits:

  • Restores proper exhaust sealing and flow.
