Viper and De Graaf exhausts: the right sound, the right fit

An exhaust you enjoy living with

The best exhaust choice starts with what you want from the vehicle: a fuller sound, a system to complement your tune, or hardware for a planned build. At Boostech Bloemfontein, we are authorised Viper and De Graaf agents and supply bolt-on performance exhaust options for supported vehicles.

De Graaf: a South African manufacturing heritage

De Graaf traces its exhaust-making roots to the early 1960s. Its range now includes performance and free-flow systems, with CNC bending used to produce accurate, consistent pipe shapes. That manufacturing background is a useful starting point when choosing hardware that needs to fit properly and work as part of a complete setup.

Viper: performance hardware for your application

Viper develops exhaust hardware for petrol and diesel cars, bakkies and 4×4s, with dyno-designed turbo exhausts and a choice of silencer materials that includes stainless steel. Its focus on fabrication and vehicle-specific design gives us options to match the exhaust to your build. We can discuss the supplied components, fitment and sound before ordering.

With either brand, we select the actual system for your model rather than assuming every product has the same specification. Tell us whether you want a subtle everyday sound or something more pronounced, especially if you spend long hours on the road.

Bring the exhaust and tune together

Many vehicles can receive a Stage 1 tune with the standard exhaust. Where your planned setup calls for exhaust changes, we can discuss the hardware alongside the calibration so you know what belongs in the build.

We also arrange decat work on selected vehicles together with a trusted workshop in Bloemfontein. Send your year, make, model, engine and current modifications for exhaust options, fitment details and a quote.
