Pulseflow offers performance-focused exhaust components and systems designed for specific vehicle applications. From BMW performance downpipes to larger exhaust systems for bakkies and 4x4s, the range gives owners an opportunity to upgrade one of the most important pathways through a performance engine: the exhaust.
When modifying a BMW engine for more power, higher RPM, or forced induction, multiple weak points start to appear across the engine.
These aren’t flaws—they’re simply the result of factory engineering prioritising:
Not all hose clamps are designed for the same purpose.
Cooling systems, fuel systems, oil lines, turbo boost pipes and exhaust components all require different levels of clamping force and different clamp designs.
Selecting the correct clamp helps:
The factory downpipe on the BMW F30 328i N20 includes a restrictive catalytic converter that creates unnecessary back pressure. While this helps meet emissions requirements, it also limits the turbocharger's efficiency and reduces the engine's performance potential.
The factory downpipe connects the turbocharger to the rest of the exhaust system. While the OEM component is designed to meet strict emissions and noise regulations, it also creates significant exhaust restriction.
A catless performance downpipe removes the restrictive catalytic converter, allowing exhaust gases to exit the turbocharger far more efficiently. The result is:
Before selecting components, it is important to determine the goal of the vehicle build. Every exhaust system is designed around the vehicle’s intended use, power level, and available space.
Common applications include:
As soon as you push your engine beyond factory limits, the stock valve springs become a weak point.
At higher revs, factory springs cannot close the valves fast enough. This leads to valve float, where the valve no longer follows the camshaft profile correctly.
The TrackAttack Pro was developed using Hoosier’s proprietary H-DNA technology, incorporating over 65 years of racing experience into a tire designed for both street and track use. Unlike traditional street tires that prioritize comfort above all else, the TrackAttack Pro was engineered for drivers who want motorsport-level performance every time they get behind the wheel.
The Hoosier R7 was developed for dedicated racing applications where ultimate performance is the priority. Unlike traditional high-performance street tires, the R7 is engineered specifically for racetrack use, delivering significantly higher levels of grip, responsiveness, and cornering capability. The tire is commonly used in:
A badly built exhaust system rarely fails immediately. Problems usually appear over time through:
