Less restriction
Larger, correctly routed pipework helps exhaust gas leave the turbo more efficiently and reduces unnecessary backpressure.

Larger, correctly routed pipework helps exhaust gas leave the turbo more efficiently and reduces unnecessary backpressure.
Improved flow can help the turbo respond sooner and makes the engine feel more willing in the low- and mid-range.
Purpose-made mounting points, flanges and routing deliver a cleaner fit than an improvised universal system.
Pairing the exhaust with a vehicle-specific Boostech calibration unlocks the strongest, safest combined result.

Common questions
A correctly sized system reduces unnecessary restriction and backpressure. On a turbo-diesel, the most noticeable benefits are normally sharper turbo response, stronger low-down behaviour, improved exhaust-gas flow and a deeper exhaust note—not an unrealistic stand-alone power claim.
The exhaust can be fitted on its own, but the best result comes from calibration written specifically for the freer-flowing system. That allows us to make proper use of the improved flow and coordinate torque, boost and fuelling safely.
Not necessarily. The final sound depends on the vehicle, pipe diameter, silencer configuration and whether a downpipe is included. Tell us whether you want refined, sporty or more aggressive and we will recommend the suitable option.
Yes. We supply systems countrywide and arrange fitment through Boostech in Swakopmund and our Windhoek support network. Availability and the correct configuration are confirmed against your exact vehicle before ordering.
