Replacement muffler #?

[turbov6joe]

I seem to have misplaced the part number for the stock replacement Flowmaster muffler, anyone know it off hand??? If there is a better flowing replacement with dual outlets, feel free to send that part number as well. I think for now I'll have the numerous little holes welded up and replace that OE muffler with an aftermarket unit. TIA

A Walker Ultra Flow (p/n WLK-17266, $110 from Summit) is polished stainless, high quality, and has no droning sound a lot of other mufflers have with the turbo motor.

The Walker TTA 3" cat-back exhaust system consists of these parts:

Walker Part #44074 First intermediate pipe
Walker Part #43248 Over-axle pipe
Walker Part #17296 Muffler
Walker Part #44279 Universal Tailpipe

Or, for a mandrel bent 2 1/2" cat back system under a single part number:

Walker Part # 17494.

I noticed that the part number for just the muffler is 17266, and the muffler from the kit is 17296...is this a typo, are they different? How much for the entire 3" kit? Am I assuming correctly that the 3" system is NOT mandrel bent and the 2.5" system is?
