G80/82/87 M2/M3/M4 Performance Downpipe

High-Flow Downpipes for BMW M3 / M4 (G80 | G82)

These performance downpipes are built with a full 3.5" diameter from the turbo outlet, paired with a precision CNC-machined stainless-steel v-band connection for a perfect fit. Unlike many options that taper down near the turbo, this design maintains maximum diameter almost to the end, delivering superior exhaust flow and performance gains.

When paired with proper tuning, you can expect gains of up to +50 HP and +60 lb-ft of torque. Each set is crafted from premium 304 stainless steel for exceptional corrosion resistance and long-lasting durability.

Cerakote Coating:
The set shown in the photos features a Cerakote thermal coating, which helps reduce under-hood temperatures and shields nearby components from heat damage. 

Performance Benefits:

• Noticeable horsepower and torque increases across the powerband

• Faster turbo spool and sharper throttle response

• Reduced turbo lag

• Aggressive, motorsport-inspired exhaust note

• Precision fitment using factory-style heat shielding

Installation Notes:
Professional installation is recommended. ECU recalibration will be required to prevent a check engine light.
