Custom fabrication · Calibration · Electronics
PRECISION BUILT. PERFORMANCE DRIVEN.
Custom exhaust systems, engine electronics optimisation and advanced solutions for vehicles where response, precision and reliability matter.
Three disciplines. One standard.
FABRICATION. CALIBRATION. ELECTRONICS.
Every project is developed around the vehicle, its intended use and the required performance. No universal solutions and no compromises in execution.

THE COMPLETE PROJECT. ONE STANDARD.
From exhaust systems and precision fabrication to engine electronics calibration and diagnostics. Every stage is treated as one connected whole.
NB FAB / Goriška
01 / Custom fabrication
CUSTOM EXHAUST SYSTEMS AND FABRICATION.
Components are developed according to vehicle geometry, thermal loads, flow, selected material and intended use. Every solution is made for a specific vehicle, never as a universal compromise.
- Exhaust and intake systems
- Custom turbo systems
- Aluminium, titanium and stainless-steel welding
- Chassis reinforcement and complex repairs
02 / Chip tuning
CALIBRATION WITH A CLEAR PURPOSE.
Software calibrations are based on the vehicle's actual condition, installed components and desired outcome. The focus is on usable torque, response and reliable operation.
- Engine ECU chip tuning
- Calibration after mechanical upgrades
- Response and torque optimisation
- Measurements, verification and diagnostics
03 / Electronic solutions
DIAGNOSTICS, CODING AND INTEGRATION.
We first identify faults precisely, then select the appropriate software or electronic solution. Every intervention is transparent and coordinated with the mechanical side of the project.
- Advanced vehicle diagnostics
- Coding and software adaptations
- Key and control-unit programming
- Electronic component integration
04 / Execution standard
DETAILSDEFINE THE RESULT.
A custom exhaust system is more than a collection of pipes. The final result is defined by geometry, joint preparation, heat control and precise fitment to each vehicle.
NB FAB / Precision fabrication Fabrication process
FROM THE FIRST MEASUREMENT TO FINAL INSPECTION.
Every project is developed around the actual vehicle, available space, loads and expected result. This keeps the mechanical and electronic sides aligned as one complete system.
- 01
Analysis and measurement
Inspection of the vehicle, available space, existing components and upgrade objective.
- 02
Geometry and material
Defining diameters, pipe routing and material according to temperature, flow and intended use.
- 03
Fabrication and TIG welding
Precise component preparation, controlled welding and monitoring of distortion and fitment.
- 04
Inspection and delivery
Verification of clearances, joints, sealing and final operation of the completed system.
05 / Performance and partnerships
FROM THE WORKSHOP. ON THE ROAD.
When the project is complete, precision is reflected in response, reliability and the experience behind the wheel.
Real-world performance
ZMOGLJIVOST, KI JO LAHKO UPORABIŠ.
The exhaust system, calibration and electronic solutions must work as one integrated whole — on the road, at events and in everyday use.
03 / Partnership
SHARED DIRECTION. REAL-WORLD PERFORMANCE.
The partnership combines NB FAB's precision fabrication with Mapetrol products for engine protection and performance. The focus remains on quality, reliability and real-world use.
Joint presence at automotive events and presentations.
A technical approach to performance, protection and reliability.
A partnership between two Slovenian brands focused on quality.

09 / Frequently asked questions
CLEAR ANSWERS. BEFORE WE BEGIN.
Essential information about fabrication, optimisation and the project process.
01 Do you build fully custom exhaust systems?
Yes. We tailor the dimensions, geometry and layout of the system to the vehicle, the available space and its intended use.
02 Which materials do you use?
We select the material according to the intended use, thermal loads, required durability and the configuration of each project.
03 Do you perform ECU and TCU optimisation?
Yes. We tailor the engine and transmission control-unit calibration to the vehicle, its configuration and the intended use.
04 Is diagnostics required before the work begins?
For electronic optimisation and more complex modifications, we first inspect the condition of the vehicle and its existing components.
05 How long does a project take?
The lead time depends on complexity, component availability and the scope of work. We confirm a more precise schedule after reviewing the project.
06 Can you estimate the expected vehicle power?
We can provide an indicative estimate based on the engine, fuel, current configuration and vehicle condition. The final figure depends on the completed setup and measurements.
07 Can you build a valved exhaust system?
Yes, when the vehicle configuration and available space allow it. We design the system around the desired sound and intended use.
08 How do I book an appointment?
Send us the vehicle details, current configuration and a brief description of the desired result. After reviewing the information, we will define the next step.
