Active Autowerke introduces the patented Signature Equal Length Mid-Pipe for the BMW G80 M3 and G82 M4. Building on expertise from the F8X M cars, this mid-pipe offers a true equal length exhaust system with a smoother high-rev sound, correcting BMW's stock mid-pipe imbalance where the driver€™s side was longer than the passenger side.

The sound character of the stock G8X exhaust is often described as muffled. Active Autowerke addresses this by offering a full exhaust system consisting of three mid-pipe options (this equal length, single, and X-pipe), a rear axle-back valved exhaust, and GESI catted downpipes. Together, these components restore the aggressive sports car growl expected from a BMW M car.

This equal length mid-pipe system is designed to fit most aftermarket exhausts using factory-style fittings, requiring only two cuts to the stock mid-pipe. Installation is bolt-on and reversible, preserving the option to return to stock configuration.

• Constructed from 100% 304 brushed stainless steel with industry-standard rust warranty
• Patented Active equal length technology for smooth high-rev sound
• Factory-style flanges and clamps included; only two cuts required
• Fits all systems utilizing factory-style fittings
• One year warranty included
• Vehicle-specific fitment for G80/G82 M3/M4
• Replaces stock mid-pipe for improved sound and flow

This mid-pipe is a premium choice for enthusiasts seeking to enhance their G80/G82 M3/M4's exhaust tone while maintaining technical precision and performance integrity.
