The last generation Holden VFII's are fitted with what is considered to be one of the best sounding factory exhaust systems to be released from Holden.

Ever wondered HOW your exhaust makes that note?

This is thanks to a very simple, Yet innovative piece of engineering called the Baillie Tip.

The Baillee Tip is named after Holden engineer David Baillee who designed the mechanical sound enhancer that ensures you'll hear your V8 before you see it.

This invention consists of a unique opening in the exhaust that reverberates the throaty, deep growl back into the exhaust towards the cabin which increases the overall sound level up to 10%.

The VFII is the most powerful Commodore to ever be released & the engineers at Holden undertook a great deal of work to ensure that the VFII has the sound to back up its performance.

The bi-modal exhaust is activated using a button on VFII’s eight-inch colour touch-screen and intelligently detects driver input to create a distinct and unmistakable engine symphony.

Upgrading to a 3" system without losing the bi-modal & mechanical sound enhancer feature

One of our most frequently asked questions for the VFII would have to be "I want to upgrade my exhaust BUT I want to keep the bi-modal feature".
