Yep did that yesterday with a welder friend of mine. I did all the cutting and fitting, he welded. The lower half of the pace setter is just pathetic. Mine was misfitted around the y pipe, it was off by a 1/4 of an inch and they just filled it with weld! Then the Y joins to 2 inch pipes to a single 2inch, then flares it at the end to mate to the stock 2 & 1/4 cat, where the hell is the logic in that??? Also had to pull 2 dents out of the primaries and complete the welds on them on the main flange, they were only tacked in place from the factory :jerkit:
The hardest part was the y pipe. Of the 5 places I checked, one could bring in a double 2 inch to single 2 inch and another could get a double 2 inch to single 2.5, which would have been perfect if it fitted, but I was looking at a week either way to get them in. I ended up buying a chromed muffler tip from a local parts store. The thing actually plugged into the pacesetter downpipe perfectly! I just cut the bottom off and mated a piece of 2.5 pipe to it. All the bends are done with mandrell 2.5 piping cut from a J bend. The whole exhaust will be 2.5 all the way from the Y pipe. I'll finish off the catback today. The header is off to be ceramic coated today as well, hopefully I'll have it all in this weekend.
