Understanding the Cost of Custom Exhausts for Vehicles in the UK

Custom exhaust systems are a popular upgrade among car enthusiasts looking to enhance their vehicle’s performance, sound, and appearance. However, the cost of these systems can vary widely, depending on several factors including the type of vehicle, the materials used, and the complexity of the installation. Here’s a detailed look at what you can expect to pay for a custom exhaust in the UK and what influences the price.

What Influences the Cost of a Custom Exhaust?

  1. Vehicle Type and Model: The make and model of your vehicle play a crucial role in determining the cost. High-performance and luxury cars often require more expensive exhaust systems. For example, custom exhausts for sports cars like Ferraris or Porsches can be significantly pricier than those for more common models due to the specialized parts and engineering required.
  2. Materials Used: The choice of material affects both the cost and the longevity of the exhaust system. Stainless steel exhausts are highly durable and resistant to rust and corrosion, making them a popular but more costly choice. Aluminised steel, on the other hand, is cheaper but less durable.
  3. Design and Components: The complexity of the exhaust system also impacts the price. Simple cat-back systems (replacing only the components from the catalytic converter to the muffler) are typically less expensive than full systems, which may include headers, high-flow cats, and sophisticated muffler designs. Additionally, the more bends and custom fabrication required, the higher the cost.
  4. Brand and Quality: Premium brands often charge more due to their reputation for quality, performance gains, and sound enhancements. Choosing a renowned brand can mean a higher price tag, but often comes with the assurance of better materials and craftsmanship.
  5. Labour and Installation: The cost of labour can vary depending on where you get the exhaust installed. Specialist performance garages may charge more than general automotive shops due to their specific expertise in tuning and performance enhancements.

Average Costs

The cost for a custom exhaust system can start from as low as £150 for a basic, unbranded cat-back system and can go up to several thousand pounds for high-end vehicles requiring complex modifications. For most consumer cars, a mid-range stainless steel system might cost between £400 and £1,000, including installation.

Cost-Effective Tips

  • Compare Quotes: Get estimates from different garages to find the best deal. Prices can vary significantly between providers.
  • Consider Your Needs: Assess whether you need a full system replacement or if less extensive modifications would suffice.
  • Look for Warranties: Opting for systems that come with warranties can provide value in the long term, protecting against defects or failures.


Investing in a custom exhaust system in the UK can enhance your vehicle’s performance and aesthetic appeal, but it’s important to consider all the factors affecting the cost. By understanding these aspects, you can make a more informed decision and choose a system that provides the best value for your needs and budget.
