I have got a remus backbox for my a3 1.8t and am looking for a centre section now. I bought the Remus as i've had remus exhausts on my last cars and the fit, finish and sound is superb. there is the option of having a straight through pipe from the cat to the backbox without a silencer or one with a silencer on it. I just wanted to find out how much louder the noise would be with out a silencer in the centre? I dont want the exhaust to be loud or drone when cruising at motorway speeds, just want a nice subtle deep tone. What have the rest of you guys got and does anyone have pictures or sound clips, I've not heard what an aftermarket exhaust sounds like on a 1.8t.
