V2 system with vacuum valves

Version 2 returns to vacuum valves, which prove more durable and consistent than electronic valves. Valves closed, you drive with factory-like calm; open, you hear the S65 V8 with an aggressive, motorsport-inspired tone. The system is brushed T304 stainless steel, fully mandrel bent and 4.6 kg lighter than stock. You choose the valved rear section only or the complete system with X-pipe mid-section, and from tips in several finishes.

X-pipe midpipe

The midpipe has an X-merge just behind the transmission tunnel, which improves scavenging and lifts midrange torque. The free flow version, without catalytic converter, has four resonators and gives the most sound and the biggest gains. The version with 200-cell Euro 6 catalytic converters has two resonators and keeps the volume in check. Sold separately, the midpipe comes in T304 stainless steel or Grade 5 titanium; it is 6.3 kg lighter than stock and works with any aftermarket axle-back.

Titanium (V2)

The Titanium Program, also called Special Ops, is for owners who want a bespoke system. Each system is built to order from Ti 6Al-4V, aerospace Grade 5 titanium, with vacuum-actuated valves. It is 23.5 kg lighter than the factory exhaust and available free flow or with 200-cell Euro 6 catalytic converters.

Frequently asked questions

Why vacuum valves instead of electronic ones?
Version 2 uses vacuum valves because they prove more durable and consistent than electronic valves. They also respond quickly.
Free flow or with catalytic converters?
The free flow X-pipe has no catalytic converter and gives the most sound and the biggest gains. The version with 200-cell Euro 6 catalytic converters keeps the volume in check. Match the choice to where and how you drive.
Does the midpipe work with my existing axle-back?
The midpipe works with any aftermarket axle-back and installs directly, without cutting or welding.
Can I go back to stock later?
Yes. The systems use the factory mounting points and can always be returned to stock.
