Designed Exclusively for Gen 3 B58 Models

Spool Performance downpipes for the Gen 3 B58 engine are built with a 4” design, precision-machined stainless steel v-band transition, and uncompromising attention to flow and fitment. Unlike most options on the market that taper down near the turbo, our downpipes maintain consistent diameter and a true 3D profile to maximize exhaust velocity and overall performance.

Crafted from high-grade 304 stainless steel, these downpipes are built to handle extreme conditions with superior corrosion resistance and long-term reliability.

Key Features:

• Significant horsepower and torque gains
• Sharper throttle response and quicker turbo spool
• Reduced turbo lag
• Aggressive, refined exhaust tone
• Precision CNC-machined construction for a perfect seal
