H&S XRT installed dpf/doc deleted
Ordered the new XRT-Pro and 5" dp back flo-pro from performance truck parts. Waited all week with the parts starring at me from the garage.
Last night my buddy and I ripped out downpipe back and installed a 5" straight pipe. The most difficult part way lying on our backs wrestling the hangers for the exhaust. We started at the dp. then the bolts behind dpf. Then the rear section. Worked the rear free, over the axle (was a hassle) and that was out. Then the dpf section was difficult because of hangars that are behind a skidplate. Once the stock exhaust was free it was a breeze. The flow-pro went in easy. I heard 5" downpipe back was a pain, there is no truth to that.
The Exhaust went in without a problem. We hung it up starting from the dp and made sure it fit. Then I tightened it down and hopped in. The xrt pro was already installed and we were out the driveway start to finish in 4 hours.
The xrt pro is pretty cool. Besides running no dpf, it has 4 tunes, calculates tire size and change top speed. The tuning on the fly is pretty rad. They say it takes 5 secs to change tunes, more like 2. I thought it had a bunch of "special features" like running high beams and fogs at the same time, turns out all that is for a 6.7 cummins.
The other thing I think is pretty cool is the "change vehicle" option. I'm pretty sure if I put the truck back to stock (dpf) that I can sell it without getting H&S involved.
The one thing I noticed, if you're going to want to change tunes without shut down / start up, you have to leave the programmer in the OBD. Right now I'm running "hot" with the tuner sitting under my back seat.
The exhaust isn't too loud. You can barely hear a difference when the windows are up. But when you romp on it, the tires will break, smoke will pour and the truck will go!
