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 systems 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 new-age (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 a full chat. What’s more, the system also includes a removable silencer for those looking not to annoy their neighbours…
This fantastic high-quality system will not only improve noise but also improved throttle response (thanks to less restriction) and power gains of up to 20bhp. Combine it with a Japspeed de-cat 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 purchase. Available for just £249 including delivery.
