    Picked up a 2002 378 48" Unibuilt, C-15. It has forward mounted fuel tanks and a single over frame exhaust system. Looking to put dual stacks on it. The over frame dual system is about 1500 to just get to the base of the stack. 800 for y-pipe alone. Not sure if under mount would clear without relocating air dryer and battery box. Kind of new to the Big trucks and would like to get some ideas. Any advise from experience is always the best place to start, so if you could send me some I would be grateful.
    Thanks

    Hi wishbone, so, you want "twin chimney's" hey? Cool. Exhaust parts are extremely expensive when you buy them 1 piece at a time, as you found out. With all the truck crashes lately, I suggest going to a truck junkyard, and maybe you can get the whole system for a cheaper price.

    Try The Chrome Depot, Mantua, Oh. 800-496-6303 Do not let the name scare you off. They have all kinds of exhaust parts at reasonable prices. Very knowledgeable about most applications.

    Walker also makes replacement exhaust parts, that should be cheaper than Paccar, if you can't find good used. you will also need the muffler mount brackets that bolt to the unibilt brackets.

    Didn't even try paccar. The prices I got were for Grand Rock aftermarket.
