Who would ever have thought we’d all be ditching our expansion chambers to replace them with big power, practical standard looking exhausts? Malossi have just released details for their own ‘big box’ Power Classic for the Vespa PX 125/150/200 models.
The Power Classic is the latest product to be released by the Italian tuning house, it’s designed to look and fit as well as a standard exhaust but is said to increase performance across the entire rev range. The good thing about a box style exhaust is that they’re quieter than a full-on expansion, they don’t cause issues when changing a rear wheel and generally they last very well. Long expansion pipes can often cause issues with rear wheel access and are prone to cracking in use.

The power Classic is designed and manufactured in Italy and works with both standard or tuned engines.
