Do yourself a favor and unbolt the vibration isolators/hangers from the frame.. there are three bolts each on those.. do this AFTER this:
Unbolt the collector plate and let it hang.. separate the mid pipe behind the dpf.. you may need to beat on it with a mallet.. it is a keyed fitting.. hit it on one side until it moves, then the other.. this will likely be the toughest part of removal..
Disconnect all the sensors at the connector.. leave sensors in exhaust..
Push the tail pipe backwards, pushing bayonets out of hangers/ vibration isolators.. when it drops down, it is hella easier to pull FORWARD over the axle than it is to pull out the back..
NOW unscrew hangers from frame.. the threads will bite frame and not allow dpf to drop.. when you're done, lie under dpf like you're about to bench press it, because you are.. get in position, move pipes toward back of truck, clearing the collector from the braces, and rest back pipe on ground.. rest front on ground.. you're done with removal..
Pull hangers off pipe and reinstall them on truck..
Install starting at collector and delete pipe.. don't tighten the bolts, just get them started.. hang them off of the hangers, which means you'll hafta twist them some to get them aligned.
Hang tailpipe piece..
Measure the distance from the delete pipe to the tail pipe, and add the depth of the flare.. I think diamond eye flares are 3" deep, so it should be the length in between the pipes plus six inches.. cut the mid pipe to that length.. I used a chop miter saw.. it took about four seconds..
Put the clamps on the pipes, slip them all together.. bolt them down, tighten the collector bolts.. you're floggin done.. this entire job won't take you an hour if you take your time.. its simple..
Caveat: TUNE tour truck first.. make sure you don't have programming problems before you start, or you'll be mighty pissed when you're down for a business day waiting for your tuning company to respond, or you gotta reverse course and reinstall the factory exhaust.. my h&s kept giving me an unknown part fault and wouldn't load.. after wiping the memory card and updating "entire card" it hasn't burped once..
Don't freak yourself out my man, this is way too easy to do, and the results are phenomenal..
