Y'all never cease to amaze me with the creative genius. I have nothing to offer but a NT style "Good Job!"

Carry on.

I believe someone alluded to this on the first page of the thread. I had the cat cut out behind the front flange and in front of the stock resonator. A straight pipe was the welded in w/o2 bung for future use. Only cost me $35 and the guy who did it said if I ever need the stock cat to bring it back and he'll weld it back in. The best part is the car sounds just like stock.

I'm thinking using an air hammer could make this a little easier. Anybody have trouble with doing this??

I did this and reinstalled, sounds good, drives good, but when it idles some whiteish smoke comes up into the engine bay. I think its some of the fiberglass packing. Should I worry or will it burn itself out?

Well as Stealth said...i get a big fat FAIL. I removed my cat and started removing the rear substrate. Today, i went to finish and cracked the front substrate and took a big hunk out of it. Thank goodness, I had already ordered another cat from Advance. Before you'll start flaming me for buying a cat from Advance it was only $234 bucks with a 5 year warranty. I put it on and now i'm back in business.....
