I have a 2006 F150 Supercrew 4X4 Lariat with the 78" bed. Does anyone know which is the correct part # for a magnaflow catback exhaust system with the long bed configuration? I've looked at the magnaflow website as well as at performancepeddler and other websites and I don't see a kit for my truck. Is it possible they don't make one for my truck? If so, anyone have experience with another brand that would have similar characteristics to the magnaflow?

 

I would call to make sure, but when I ordered my 1st kit for my truck (flowmaster) it came with extension pipes for the longer bed and that was it.

 

It depends on how you want it to exit, if you want dual split rear exit under the bumper then get #16520. For dual same side exit behind tire get #16523.

The 16520 replaced the 16614. the old 614 kit fit scabs w/ 5.5 bed (133 wb) screws w/5.5 (139 wb) and scabs w/6.5 (145 wb). The new 520 kit fits screw 5.5 (139 wb) scab 6.5 (145) and screw 6.5 (150 wb). The 523 kit is a new kit, harley style exit, and they automatically made it fit the screws w/6.5 bed. The old SI/SO kit (16612) does not fit your truck.
