Unlock the full performance potential of your BMW G80 M3 / G82 G83 M4 with our S58 Catted Downpipes, engineered for power, precision, and reliability. Designed to enhance exhaust flow while maintaining emission compliance, these high-flow 200-cell downpipes deliver a deeper, sportier tone and measurable gains in horsepower and torque — all without triggering a Check Engine Light (CEL).

Constructed from premium 304 stainless steel, each downpipe features integrated flex sections for improved fitment and vibration absorption, as well as CNC-machined flanges for an OEM-quality seal. Perfect for both tuned and stock setups, this upgrade brings a balance of performance, durability, and refined sound.
