Holden Commodore - VN 8 cylinder
Take advantage of our years of experience as we explain the best options for your car.
The Exhaust System
As with most of the VN-VS Commodore range we recommend either a single 3 inch cat back sport system or a dual 2.5 inch cat back sports system for the VN V8. Both systems will come with a straight throw sports performance muffler. They will both create a great new flow which will improve the performance of your car. The key difference is the sound.
The single 3 inch system will give a good deep note. You will get a
smooth note that will give a good grunt under acceleration.
The Dual 2.5 inch System
The dual 2.5 inch system will give you a great new grunt. This system is
sure to be a head turner. It will be loud but we can keep the sound down if you prefer to be quieter. The dual system is only available if the VR has independent rear suspension (IRS).
Fitting a set of extractors will give you more power. These extractors also have the potential to improve your fuel economy and engine efficiency under normal driving conditions. We believe that Pacemaker Headers are the top of the range when it comes to the V8 VN Commodore.
The Hi-flow Cat Converter
You may consider replacing your stock standard cat converter with one of our hi-flow cats. Our hi-flow cats have a greater surface area than regular cats and therefore encourage a better flow of gases from the engine, and less restriction.
