At Valvetronic Designs, we believe enthusiasts deserve the ultimate driving and sound experience. That’s why our pursuit of perfection for the G01 platform has resulted in one of our finest exhaust systems to date.

Engineered using lessons from our most successful designs, this system utilizes the maximum possible piping diameter to unlock a raw, unfiltered sound when the valves are open. The result? Explosive turbo spool, aggressive overrun, and an addictive tone that sings from idle to redline.

• Constructed from T304 Stainless Steel

• 3.5-inch midpipe for optimal flow and sound

• Dual actuated valves for unmatched longevity and flexibility

• Includes standalone valve controller

• 25.5 lbs lighter than the factory exhaust

• Precision TIG welds for high strength and durability

• 100% reversible—return to stock at any time
