Custom Exhaust Systems
Using only the highest quality T304 stainless steel, we design and build bespoke exhaust systems tailored to your vehicle and your goals. Our stainless tubes range from 1" to 5" and all fabrication is done on-site, from performance upgrades to full end-to-end custom systems.
- Bespoke stainless steel exhausts, built to your specification
- T304 mandrel bends for tight angles and a distinctive look
- Custom wastegate pipes, flanges and screamer pipes
- Enhanced sound and appearance, while staying street legal
- Lifetime guarantee
ECU Remapping
The Engine Control Unit manages fuel delivery, ignition timing and throttle response. Manufacturers limit these settings to suit global regulations and fuel standards. We reprogram your ECU through the OBD port to unlock the engine’s full potential, with every remap tested and backed by a performance report.
- Increased horsepower and torque
- Improved throttle response and safer overtaking
- Improved fuel economy
- Tailored to your make, model and driving style
DPF & Hydrocarbon Cleaning
A blocked Diesel Particulate Filter reduces performance, raises emissions and can lead to costly repairs. We remove the DPF, clean it thoroughly and refit it, and we also offer manual regeneration with hydrocarbon cleaning to restore performance.
- Restores performance and fuel efficiency
- Keeps your vehicle MOT compliant
- Signs to watch for: DPF warning light, loss of power, poor economy, frequent regenerations
- Regeneration, deep cleaning and replacement available
