Active Autowerke - BMW M3/M4 Midpipe With X Pipe (G80/G81/G82/G83)
Tax included. Shipping calculated at checkout
Description
The Active Autowerke Signature Mid-Pipe with X-Pipe for the BMW G80 M3 and G82 M4 is designed to transform the sound of these high-performance cars. While praised for their exceptional handling and power, the factory exhaust leaves something to be desired in the sound department. Active Autowerke's exhaust upgrade addresses this by delivering the unmistakable sports car growl expected from a BMW M-car, ensuring that drivers truly feel connected to their machine.
This system includes a mid-pipe, rear axle-back valved exhaust, and optional GESI catted downpipes. Whether you opt for the catted or catless version, this full system produces an enhanced exhaust tone. The catted version provides a slightly deeper tone while maintaining volume control, whereas the catless option offers the maximum volume for those seeking an aggressive sound.
Key Features:
- Compatible with most aftermarket exhausts: This system is designed to work with a wide range of aftermarket exhaust systems and mufflers, requiring only a single cut to the stock mid-pipe for installation. It's a bolt-on system that can easily be reversed if necessary.
- Improved exhaust flow: By removing the restrictive secondary cats and resonators, this mid-pipe increases exhaust flow, improving both sound and performance. An available upgrade includes high-flow 100-cell flat cats for deeper exhaust tones.
- Scavenging effect with X-Pipe design: The X-pipe configuration helps equalise exhaust pulses, yielding modest horsepower gains.
- Premium construction: Made from 100% 304 brushed stainless steel, the mid-pipe offers durability and corrosion resistance, backed by an industry-standard rust warranty.
- Future upgrade potential: Plans for a resonator upgrade will offer options for those who prefer a smoother exhaust sound.
This upgrade is a must for enthusiasts who crave a better-sounding car that matches the incredible performance of their BMW M3 or M4.
