Exhaust difference on cab/chassis vs "normal" trucks?

**PressureDrop** · #1 (**permalink**) 02-22-2013, 12:06 PM

Several of the aftermarket exhaust systems say they are not for cab/chassis trucks. Anyone know why?

In particular, I have a 2011 F450 cab/chassis, and I also have an MBRP 5" DPF-back S6252 exhaust sitting in my garage. Does anyone know why it definitely would not work?

well I just took the stock filter back section off and compared it to the MBRP and they are totally different, so no go on using it heh.

I know for a fact that it works great on "normal" complete build trucks though! This one has been cut already for the crew cab/short box (156" wheelbase) so it would fit that or a super cab short box, but no cab chassis

Yeah it's cuz the after axle fuel tank. Doesn't allow as much room for the exhaust to exit so it has a different bend to get around the tank.

different bend, different hanger

Looks like when I make the move, it will be a stack!
