⚙️ Key Features

• Deeper, More Aggressive Exhaust Tone – Replaces the stock exhaust’s muted sound with a rich, sporty growl that enhances every drive.

• Premium 3.5” Diameter Piping – Designed for optimal exhaust flow, reduced backpressure, and improved throttle response.

• Precision-Crafted Cross-Brace with Laser-Cut LAB Logo – Adds both structural support and a premium underbody aesthetic.

• True Bolt-On Installation – Direct-fit design with no cutting or welding required (Professional installation recommended).

• Active Valve Control System – Seamlessly integrates with factory drive modes or use the included LAB remote to open valves on demand for maximum sound.

💡 Note: Factory drive modes may not fully open valves at low RPM or while stationary. Use the remote controller for unrestricted exhaust tone when desired.
