This Valvetronic Designs valved axle back replaces the muted factory rear section with a Grade 5 titanium exhaust built around electronic valves, giving the twin-turbo inline six a proper voice while keeping volume fully under your control.\u003c\/p\u003e\n\u003cp\u003eWith the valves open, the car takes on a sharper, more aggressive tone that builds all the way to redline. Close them and it settles back to a refined, near-stock volume for early starts and long highway stretches. Because it bolts to the OEM mounting points and leaves the rest of the exhaust untouched, this is a fully reversible upgrade that does not commit you to a complete system.\u003c\/p\u003e\n\u003ch3\u003eWhy Upgrade the Factory Rear Section?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransforms the heavily muted factory exhaust note into a rich, engaging sound\u003c\/li\u003e\n\u003cli\u003eElectronic exhaust valves switch between aggressive and quiet on demand\u003c\/li\u003e\n\u003cli\u003eGrade 5 titanium construction is significantly lighter than the factory steel rear section and resists corrosion\u003c\/li\u003e\n\u003cli\u003eQuad exhaust tips in a choice of finishes match the look of your build\u003c\/li\u003e\n\u003cli\u003e100% reversible, so you can return to stock at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSound and Valve Control\u003c\/h3\u003e\n\u003cp\u003eThe axle back integrates electronic exhaust valves and ships with a valve controller kit, so switching between loud and civil takes seconds.
