Active Autowerke Goliath Race Exhaust - 2021+ BMW G80 M3/G82 M4

This exhaust system upgrade was designed and engineered to replace the entire exhaust system with only no cuts needed in the stock exhaust. It is a bolt-on that can be performed by most and the stock exhaust can be reinstated if needed.

This system provides the maximum flow available and provides a race car growl expected but not often realized from a BMW M-Series car. The resonators reduce some of the rasp from the S58 engine without compromising the wide-open sound.

The Active Autowerke race only exhaust system is constructed of 100% 304 brushed stainless steel and has a industry standard warranty against rust. This latest addition to the Signature line up is a must for the true Enthusiast looking for a better sounding car to match amazing performance.

Features:

• Durable 100% 304 Stainless Steel
• No cuts needed with Factory Style Flanges and clamps
• Install using factory style fittings
• One year warranty
• Replaces stock exhaust for race sound and maximum flow.
