Noyz Boyz is awesome! Although it was a little more expensive than I had hoped, Sav treated me right. They had to cut the exisiting cat just below the egr to maintain the flange to the header and then cut the cat pipe just before the o2 sensor. Then there was an issue with the length of the new cat to be inserted and welded so they cut the neck off the new cat. Welded everying thing together and put a small piece of mandrel at the bottom of the new cat to the existing 2 inch pipe to finish it off. The cat supposed to be the freeest flowing cat that is emissions legal - rated for a 6L motor. The old cat was fawked, the screens (are they made from silicon or a crystalline of something?) had all broken away and were crumpled in a ball blocking the outlet... no wonder it was choking up. Back to good now, and a bit more peppy too. If you ever suspect this is happening, make sure you do something about it. I suspect that kind of back pressure could cause the valves to bend or something - either way, not good.

Anyway, happy again :D
