change the backbox and you'll notice a sound change, the biggest increase in burble is taking the cats off though.

any reason y you want to keep the cats?

have a look on you tube at the various vids of imprezas with exhausts, this gives you a good idea of the different sounds etc the different systems have :)

well... to be honest, there is no reason...i just dnt undastand the whole cat thing....:idea: :idea: ..

as long as it doesnt affect the ecu or anything else..

plz feel free to explain..
