G30 Quad Exit Exhaust

For off-road / competition use only. Not legal for use on public roads in the United States, including California. You're responsible for following the laws where you live and drive.

This is a custom-made axle-back for the G30 540i. It replaces the factory trapezoid tips with staggered quad tips. It's the exhaust on our own G30.

What it's like

• Looks: staggered quad tips that line up with the stock diffuser or an aftermarket M5-style diffuser.
• Sound: quiet enough to daily drive, with no annoying drone. It opens up at higher RPM under acceleration. Watch the cold-start video above.
• Fit: bolts on in place of the factory rear section.

• Orders ship from Dallas, TX in 1–2 business days.
• Free US shipping on orders over $250.
• Unused parts can be returned within 30 days. Some items are marked no-refund in their description.
