As per title really. Can anybody describe the sound? Is it deeper? Raspier? or a combination of the two? And how much quieter than the non res is the resonated version of the milltek and is it still louder than stock? To make it easy for me to understand, in terms of percentage, how much louder is each over a stock exhaust approximately? Can't decide which to go for, I'm after an improvement in tone but I don't want to deafen the neighbors either. But I don't want to blow best part of 500 quid on the resonated version if it gives little change in sound. And once I've bought and fitted it it's too late to change my mind. Driven gently, will either be obtrusive? I aim to get stage 1 mapping this year with a view to possibly increasing that later on so I can add sports cat and downpipe at a later date if needs be.
