can you get the pipe off behind it? If so you could punch it out and be flowin freely again!

Just take off the pipe so you have a straight shot at the contents of the cat, and take a big long bar or something (I've used a jack handle before) and break it up enough to fit out the outlet. Start it up and rev er to blow the stuff out, I'd suggest something to catch it too.... be careful not to break the O2 sensors if you do this

We have done this too at the muffler shop, which produced two other issues, #1 the "droning" sound inside the cab (which was why we started installing the additional short glasspack) and #2, a constant CEL showing "out of perimeter" O2 readings.
Just a few things to think about, most of the "droning" issues were GM related and most of the CEL issues were Ford related, didn't do too many Dodges.......

im running a glass pack with the cat still on it and it sounds great i think its like a 34" glass pack not to loud but has a pretty good rummble to it doesnt do the loud pop or crap like when you straight pipe a truck if your going to straight pipe your truck atleast put in a glass pack to help somewhat take the annoying pop.
