Our custom-built exhaust facility serves the North West and beyond, and is located a short distance from the M53 motorway in between Chester and Liverpool.

Hand crafted in T304 grade stainless steel by experienced technicians, we can build replacements for any original equipment or aftermarket exhaust. Whether a full system, part system or a basic repair, our Custom Build exhausts are fully guaranteed.


The Cybox Custom Build exhaust bays are totally unique in that they operate under the same roof as a volume exhaust manufacturer, and therefore share the vast resources and expertise required to produce the highest quality exhaust products. Our exhaust product ranges are supplied to a growing portfolio of respected global trade and private customers.

So why are we so different?

A quick Google search will list a large number of Custom Build exhaust centres. Quite simply, the majority have very limited facilities and use light duty bending machines which compress and distort the tube during the bending operation. This results in a 20% reduction in bore on a shallow bend, and a 30% reduction on a tighter bend. An exhaust system is only as good as its weakest link, so why compromise performance and settle for restrictive sub-par bending? In addition, they do not manufacture silencers in-house, and can only draw off a limited range of exhaust silencers and components.

By contrast, Cybox Custom Build Exhausts guarantee the following:

  1. Mandrel Bent Pipework with no reduction in bore. Anything less will cost performance. Please read our full Mandrel Bending guide
  2. The right external silencer dimensions and the best internal design, to provide an exact fit and the sound level required. If we do not have a suitable silencer off the shelf, we will make it.
  3. The widest range of silencer options, tailpipes and other components
  4. Manufacturing expertise and dedicated staff who have been building exhausts for many years. We are 100% exhaust manufacturers and do not offer this service purely as a sideline.

Our prices are extremely competitive, and we guarantee you will receive the best possible fit, sound, performance and looks without compromising material quality or cutting corners by using inferior components and equipment.

We welcome enquiries for all cars, motorcycles, vans, campers, trucks and agricultural vehicles.
