    True Dual systems vs y-pipes

    I am full out modding my 2002 WS6 in July and want to do it right. I am already getting Pacesetter long tubes and a Corsa cat-back. I want to know if I should get a y-pipe or true dual exhaust. What's the differece, and is the true dual going to be much louder than the y-pipe? I am not looking to make my car obnoxiously loud, for it's my everyday car.

    the true duels would make the car VERY loud. TDs dump at the axle unless you get fab to take the pipes all the way back. if your pipes do dump at the axle its going to be really loud in the cab. i think TDs sound nice, but i think its easier to go with a y pipe and a catback. and there isnt much of a HP gain by going with TDs

    LTs, y and catback sound nice, if u want to get obnoxious lose the cats. happy modding

    The exhaust shops will tell you so...
    Think of a big tip as trumpet they told me. It sounds reasonable, the bigger it is all the way back the louder so the tips probably makes a small difference.

    I went with the double tips on each side or whatever you want to call them, sounds good to me, though bigger would be louder or so they(several shops) told me.

    I have TSP True Duals with X pipe and sweet thunder mufflers. I had a SLP Loudmouth II and the true duals sound much better. They are loud but its not a daily driver for me, only track and pretty days.

    True duals doesn't mean it'll be loud. A single straight pipe with no muffler would be louder than duals for example.

    Duals can sound quite nice, as long as you have proper noise control in each dual. An x-pipe will cut down on the raspyness, and a good muffler can give a dual setup a very nice, and not overwhelming sound.

    Dont want to hijack this thread but what do you guys thing about true duals with an x-pipe and with two electric cutouts on an undecided location? Where would the cutouts fit best? And would they be before or after the xpipe? Anyone here have done this?
