This combined silicone front mount intake and stainless steel downpipe kit from Fupower provides a complete intake-to-exhaust upgrade in one package. By optimizing both cold air delivery and exhaust outflow simultaneously, it unlocks measurable horsepower and torque gains, sharper throttle response, and a deeper, more aggressive V8 exhaust tone for the G90 M5 platform.
High-Flow Stainless Steel Downpipes
Crafted from premium SS304 stainless steel, each downpipe features precision mandrel bends and clean, consistent TIG welds for maximum strength and leak-free performance. The material resists corrosion and extreme exhaust heat, standing up to both daily street driving and hard track use.
By replacing the restrictive factory catalytic converters with a free-flowing straight-through design, these downpipes dramatically reduce exhaust backpressure. This allows the twin turbochargers to spool faster, deliver smoother mid-range power delivery, and produce a deep, throaty V8 exhaust note with clear turbo whistle under acceleration.
Integrated stainless steel flex joints absorb engine movement and thermal expansion, preventing pipe cracking and exhaust leaks over long-term use. Every flange and mounting point is machined to exact factory turbo outlet specifications, ensuring a perfect, gap-free seal.
Silicone Front Mount Intake System
The front-mount intake design relocates the air filters to the front of the engine bay, drawing in cooler, denser outside air instead of heat-soaked under-hood air. Denser intake charge improves combustion efficiency, delivering more consistent power output and more immediate throttle response.
Multi-ply reinforced silicone intake tubes replace brittle factory plastic piping. The material resists heat degradation, vacuum collapse and cracking under high boost conditions, maintaining consistent, uninterrupted airflow even under harsh engine bay temperatures. A smooth inner bore eliminates airflow turbulence for maximum efficiency.
Included high-performance cone air filters provide far greater airflow than OEM paper filters, while reliably trapping dust and road debris. The filters are washable and reusable, reducing long-term maintenance costs for both daily driven and track-focused builds.
