supersix vaccum lines?

cool thanks. i managed to find some info on the slant site. im going to put 2 1/2" single pipe on the duster too. i already had a lot of guys tell me its not worth it, but to me it is, i have a bunch of 2 1/2" mufflers and some pipe, i just have to order up a couple mandrel bends. i made sure ot open up the outlet of the exhaust manifold before i put it on the car.
