Simpson Race Exhausts

What Simpson Race Exhausts does

Simpson Race Exhausts is a UK-based specialist manufacturer of bespoke exhaust systems for the motorsport industry, performance car market and motorcycle market. Founded in 2001 by Matt Simpson, the company operates from a 3,500 sq ft workshop and office facility in Langley, Berkshire, near Heathrow Airport and the M4-M25 interchange. Its product portfolio comprises seven core lines: complete Exhaust Systems (covering F1, Le Mans, NASCAR, WRC, touring cars, drag cars and motorbikes), Manifolds, Tubes, Silencers, Collectors, Bends, and individual Exhaust Systems & Components. All products are handmade using Stainless Steel 304 and Inconel tubing.

The company's underlying technology centers on specialist metalwork rather than software. Tubes are manufactured in-house in diameters from 1 1/4 inch to 3 1/2 inch, with Inconel tube produced from flat sheet to any diameter for lightweight, high-temperature applications. All welds are TIG welded and gas purged with pure argon to ensure smooth internal surfaces for improved gas flow. Manifolds are mandrel bent and equal-length branched, then proven on an in-house dyno to deliver measurable horsepower and torque gains. The company also operates in-house silencer noise testing for track-day compliance applications.

Commercially, Simpson Race Exhausts runs a direct-to-consumer bespoke manufacturing model with no disclosed pricing, customers quoting via phone or email. Orders are placed by phone (+44 (0) 1753 532222) or through the company's online store. The customer base spans named enterprise motorsport accounts, including Millington Racing Engines (standard supplier for all Millington engines) and Lola Cars International (main exhaust supplier), racing championships (F1, Le Mans, NASCAR, WRC, Formula 3), BTCC touring car teams, rally teams, and individual performance car and motorcycle enthusiasts. The team is small (seven named individuals) and the business is founder-owned with no external institutional funding or parent company.
