![]() Then there is the MK5000C which is powered by a turbocharged CAT prime mover and it has 1 exhaust stack. If you take a look at the MP1500D's and MP2000D's offered by Boise Locomotive you will notice that they have 1 exhaust stack and that they are powered by CAT prime movers. I don't know where you came up with the idea that 4 exhaust stacks indicate a CAT prime mover, but thats not true either. This was a standard feature on all of the GP8, GP10 and GP11 rebuilds that were outshopped by the IC's Paducah shops. Plenty of old GP7's and GP9's have been equiped with the additional exhaust stacks. Missouri Pacific was very fond of the 4 exhaust manifold most if not all of their GP35M's, GP38's, GP38-2's, GP15-1's and GP15AC's were equiped with it as well as early model Geeps which may have aquired it during rebuilding. ![]() Non-turbocharged units with 4 exhaust stacks are very common. Both of these 6000 hp locomotives have prime movers with dual trubochargers which require the dual exhaust. The AC6000CW also has large dual exhaust stacks which are side by side and are clearly visible on the roof over the engine compartment. The SD90MAC-H has 2 exhaust stacks which are located side by side though they are recessed into the roof and not really visible. These days not all turbocharged locomotives have single exhaust stacks. To start, Conrail never repowered any of its locomotives with Caterpillar prime movers. Essentially the use of One Large stack indicates the use of a Turbocharger on the prime mover while 2 stacks indicate a normally aspirated prime mover and these days 4 would indicate that a Caterpillar prime mover is under the hood<< Imagine a set of 6" Bullhauler turnout stacks protruding from the bed! And you wouldn't believe the shuddering sound they produce, either!Īs always, if you have any questions about which exhaust is right for you and your truck, do not hesitate to give us a call or send an e-mail to and we would be happy to assist.>Although I do beleive that Conrail did have some units rebuilt with Caterpillar prime movers which may have 4 exhaust stacks on those units. And for those looking for something even more unique, try out a set of exhaust stacks by MBRP. ![]() ![]() For those looking to also replace the factory flattened out turbo direct pipe, we offer several high flow units that are sold separately from the exhaust kits. We offer a cat back system, for those looking for a simple installation with great sound, as well as a turbo direct pipe back that eliminates the catalytic converter, considered an "off-road" kit. ![]() We offer several different configurations for your new exhaust kit. And of course, there are other benefits to adding an exhaust kit besides purely functional, aftermarket kits not only sound good, but they look even better, especially with a nice tip to finish it off. While this system is reasonably adequate for stock to mildly powered trucks, a larger diameter system or higher flow system from Diamond Eye, Magnaflow, MBRP, Mel's Manufacturing, or Silverline is mandatory on any Duramax equipped with even mild upgrades, or for those towing heavy loads. The 2001-2004 6.6L LB7 GM Duramax's came factory equipped with a 3.5" turbo back aluminized exhaust with a catalytic converter and muffler. ![]()
