A stainless steel, 6-2-1 header designed to improve exhaust flow and responsiveness. Tailored fit targets selected 1996–2006 BMW 2.5L–3.0L engines.
More usable mid-range power - with a 6-2-1 light header design
Primary pipes route each cylinder into staged collectors, using 1.75" primaries and a 2" outlet to manage exhaust pulses. The 6-2-1 configuration encourages scavenging at mid-range revs while smoothing the flow toward the collector.
Improved mid-range torque and clearer throttle response, practical for everyday overtaking and spirited drives.
Reduced cylinder interference, smoother exhaust pulses - with dedicated primary pipes
Each cylinder has its own primary pipe, which prevents end interference between neighbouring exhaust pulses. The smoother, less turbulent flow converts more exhaust energy into usable power to the wheels.
Cleaner exhaust flow results in crisper throttle feel and a noticeably more responsive driving experience.
Durable, install-ready construction - with stainless steel and thick flanges
Brand new stainless steel construction and thicker flanges aid rigidity and sealing at the manifold face. Tailored dimensions for E46 (select), E39 and Z3 help achieve a close-fit mounting pattern.
Longer service life than many stock manifolds and a more secure flange seal, reducing the chance of leaks after fitting.
✨ The 4 Key Reasons for VIPIH Exhaust Header
- Optimised exhaust flow - Smoother mid-range power for everyday driving
- Cylinder-by-cylinder primaries - Reduced interference, clearer throttle response under load
- Stainless steel construction - Corrosion resistance and durability for long-term use
- Designed for bolt-on fitment - Tailored fit reduces workshop modification and fitting time
