I have a P1 STi backbox on a MY97, apart from that the exhaust system is standard. The only other concession to performance is an ITG filter. After hearing a scooby with what I think was a full scoobysport system (and sounding not unlike an old TVR v8 - lovely)I realise that I must have more throb (titter titter). Could anyone explain what is the cheapest easiest option from here – I don’t want to change the whole sytem removing both cats etc? I want something that’s nice and burbly at tickover rising to a shrieking crescendo (well almost) when one is going full pelt.
I have a standard exhaust with ss back box nice throb from it not too bad inside. Mates tell me it sounds good pulling away ( I've never been outside it !)
