Take control of noise
Managing engine noise, smoke and vibration, as well as your overboard discharges, is becoming increasingly important as we all become far more aware of the impact we are having on our surroundings - quite apart from making boating more enjoyable!

We offer the most advanced products available to achieve this, be it simple engine noise, a sophisticated and specially designed exhaust system, or a filter to remove oil from bilge water before it is pumped overboard. Everything we make can be tailored to suit your needs, and we support our products with excellent levels of customer service.

We develop new products continually, to achieve cleaner, quieter exhausts and to improve value for money.

Whatever the project: lifeboat; commercial pilot; family yacht; high volume production boat or a one-off Superyacht; our designers will get involved from the earliest stages, consulting on and designing systems to best meet the requirements of your project.

Once complete, we will warrant the design to achieve agreed levels of noise reduction. We will also warrant exhaust systems, to achieve agreed back pressure levels.

We manufacture a wide range of stock components for exhaust systems and noise and vibration reduction, and help customers to agree systems using standard components available rapidly and at low cost.

Our Services & Products
Design
One off design and production
• Stocking and delivery scheduling for production lines
• Complete exhaust systems from turbo to transom

We manufacture our exhaust systems almost entirely in house, and in Britain, with three factories producing silencers, exhaust hose, and stainless water injection systems. We design systems for customers world-wide.

Our Mission
Our mission is simply to please the customer with helpful service and technically sound products, delivered on time and within budget, to give many years of problem free service.
