dpf/cat question

I've ordered my dpf/cat delete and have a question where the flange comes off of the downpipe how are you guys getting the bolts out because they look like they are tack welded.

I have not done mine yet but I believe that the nuts are tack welded. the bolt is removed from the front, or at least whatever is in the front is what is removed, but I am sure more that know more will chime in

the nuts are tack welded and the bolts come out if i remember correct...get extensions a FEW of them ....and a flare nut wrench helps ALOT on the sensors.......

yea 08stroker250 is right...just make sure u dont get a cheap flare nut wrench im not saying the sensors are hard to get out but they didnt come right out for me and make sure to unplug them before u lower the dpf and exhaust down and then unscrew them once u have it from under the truck its easier

If you are having problems with getting the sensors out, try to get your hands on a torch. Lots of heat will really help getting them out
