Just listen to the wonderful sound produced by this x-pipe cats system, fitted to a Porsche 911...

...The extra size of this full catalytic system is accommodated by tapering the pipe down from 63.5mm to the standard 55mm. This means the systems fits directly onto a standard set-up, with no fiddling about or alterations to the car itself.

These are a unique design optimised for sound and power with a larger bore 2.5" allowing greater gas flows, incorporating top of the range 200 Cell catalytic converters. Fabricated here at Head Office in Bridport, Dorset, this kit is currently only available to purchase through our eBay shop, so you'll have to hurry if you want a chance to see these big cats in the wild!
