Gotham Hi Flow Cat Installed
The only difficulty with the install is the air pump line, but overall not too difficult. It bolts straight up, and all you have to do with the air pump line is saw the original metal line off the stock cat...it's bigger in diameter than the inlet welded to the gotham cat, so slide it over top the inlet piece (if you need to bend the inlet at all just torch it for a few seconds move it the way you need and weld it in place, and bolt the original air pump back together and you're done
It sounds really good...little deeper at idle, but not much, it's once you hit boost that it really sounds different...makes the 7 scream...over throttle respone is much better, and the turbos spool a lot quicker...pulls a lot harder too without that stock cat, and not to mention probably weighs 20-30 lbs. less than the stock one

I didn't cut anything when I did my install. I just got some correct sized hose from the local autozone and some good hose clamps. Took all of 5 minutes to measure/cut the hose and then install it.

Glad you like it. That stock main cat weights a ton.....back a few years ago when I swapped in a midpipe in my garage, the damn main cat almost fell on my head. That would've hurt like a **** .

Just buy a midpipe. Gutting the cat is not nearly as good an option for two reasons. One, because the cat is much wider than the reast of the piping, you're going to have a lot of turbulence, slowing down airflow, increasing lag time, and it's going to cause less HP than just a midpipe. Two, it's still a lot of metal (weight), and it is ooooold.

I completely agree. A midpipe is inexpensive and a much better choice then gutting the cat. There is are some situations where you can and should save $$ when modding, and this definitely isn't one of them.
My 7.9 cents

I'm stickin with my airpump, but I talked to a guy at a muffler shop near my school who knows his stuff, and said that without the airpump there is not enough air flow through the cat to allow the catalyst to do its job and convert the exhaust gases into more environmentally safe ones... so I would say from that, that your cat won't do its job without proper air flow and will begin to clog, but not as fast as the stock one considering it has less restriction allowing for more air flow
