The Subaru Impreza flat-four is one of the most unique engine notes in the car world, so it seems a downright shame that the factory exhaust system quietens down the noise to a near silence as well as restricting horsepower. Japspeed know enthusiasts want that classic grumble from their cars even at idle, and as such has designed the perfect system for the NewAge, (GDA/GDB models) the two piece catback system.

Manufactured from mandrel-bent T304 stainless steel for maximum longevity, the Japspeed system features a 3 inch bore all the way through with a 4.5 inch tailpipe. The end result is a much more prominent grumble at all speeds, which sounds awesome at full chat. Whats more, the system includes a removable silencer for those looking to not annoy the neighbours…

This fantastic high quality system will not only improve noise but also improve throttle response, (thanks to less restriction) and power gains of up to 20bhp. Combine it with a Japspeed decat downpipe and you’ll find the Impreza really is transformed!

As with all Japspeed products, all gaskets and bolts are included – you won’t be dissapointed with this product. Available for just £249 including VAT and shipping.
