3 Inch Bi-Modal Cat Back Exhaust System

The WP/Harrop Pro Series exhaust is the perfect way to make your GTS sound as good as it looks.

These systems will give your vehicle a deep throaty growl which will get the heart pumping. Our systems will complement your vehicle whether it be standard or upgraded with one of our upgrade packages. We have a range to suit every application.

Our new Pro Series exhaust systems are constructed using 409 stainless steel to ensure that they last the distance. The location and style of the inlet is the same as the standard HSV/Vauxhall system, so it can be used with the standard exhaust manifolds and catalytic converters.

The Bi-Modal option enables you to retain the aggressive exhaust note when you want it, while reducing loudness during everyday driving conditions.

Applicable Vehicle(s) Vauxhall VXR8 GTS (VF & VF2)
Price £2,735 inc VAT.
