Not sure if this is the the correct area to put this message, but here goes. I have just taken delivery of my 55 plate MY06 Impreza 5 door WRX, which I love. I have just had a lowering kits fitted by the dealer I bought it from, but I am now after a rear back box for it. Not too bothered about performance although any increase but considerably help. But can anyone recommend a good rear box to add to the system on the car now or even a complete system. I do not want to spend a fortune, but I do want to to sound very nice. What is the exhaust that the imported Impreza's have on them? as they sound awesome. Can someone please recommend something and give an idea of how much, where from and teh add performance it may give. Plus can anyone recommend a place in Cheshire to have this work done?
