Replaced my Y-Pipe today. Picked up a Walker Y-Pipe assy. from Rock Auto for 165.89 plus $48.00 2 day shipping to Hawaii. Even with an impact wrench it took me about 4 hrs mainly cause I broke 2 sawzall blades trying to cut out the converter bolts and several dremel cut off discs. Total time under the car maybe 2 1/2 hrs.
The manifold pipe nuts was stubborn but finally came out after I applied some heat from my map torch. It also helped after I got a 1/2" extention. Someone had posted about using a 3/8" extension bar with 1/2" adaptor vs the 1/2" bar, much easier with the 1/2" extension bar. On the forward pipe both studs came out and the rears only the nuts. No problem cleaned the threads and bolt and it torqued up fine.
Car is so much quieter now. I was quoted by a local muffler shop $185.00 for the flex pipe only and about $80-$90 labor.
