Maserati Quattroporte Control Axleback + X Pipe

Control the sound. Transform the tone.

The 2003–2012 Maserati Quattroporte Control Axleback + X-Pipe combines a valved Control axleback system (rear section) with an X-pipe center section, delivering a complete upgrade in both sound character and exhaust flow.

The X-pipe improves exhaust scavenging and balances flow between both banks, resulting in a smoother power delivery and a more refined, high-pitched Maserati V8 tone. Paired with the valved Control axleback, you can cruise quietly with valves closed or open them to unleash a deeper, more aggressive exhaust note with increased volume and presence.

Constructed using precision TIG welding and mandrel-bent tubing, every component is built to withstand extreme temperatures while maintaining optimal flow efficiency. Designed as a direct bolt-on system, installation is seamless with no cutting required.

Refined when you want it.
Unleashed when you need it.
