How much horsepower does a performance exhaust add?

A high-quality BMW performance exhaust system enhances vehicle performance by reducing backpressure and improving exhaust flow. While results vary depending on the specific BMW model and setup, a well-engineered system typically can deliver an increase of up to 5% increase* . To extract the maximum potential from these upgrades, we recommend combining the exhaust with a custom VIEZU performance remap. * results will vary depending on the model and set up of the exhaust.

What makes a BMW 'pop' and crackle?

The signature "pops and bangs" are achieved through a combination of non-resonated exhaust systems and specialised ECU remapping. Non-resonated exhausts remove sound-dampening chambers to produce a rawer, more authentic note. When paired with "Pop & Bang" tuning, the engine management is adjusted to create a symphony of aggressive crackles during deceleration or off-throttle moments. A "pop and bang" remap is considered illegal for road use in the UK if it causes the vehicle to exceed legal noise limits or violates emissions regulations

What is the benefit of a performance exhaust over the standard BMW system?

BMW factory exhaust systems are often conservative, designed to meet global noise and cost restrictions which can restrict the engine's ability to "breathe". BMW performance exhaust systems use mandrel-bent pipework and premium materials like T304L stainless steel to reduce weight and backpressure. This results in sharper throttle response, increased power and a more refined, sporty sound profile.

Are BMW performance exhausts road legal?

Most BMW performance exhausts are fully road-legal and compliant with MOT emissions and noise regulations. However, specific high-performance modifications (such as de-cat pipes or certain sports catalysts) are sold strictly for motorsport and off-road use.
