Down pipe

[biff101]

Did my install today. Read a few of the write-ups and that got me through it rather quickly. I had to the bend on the flange as everyone stated. Then welded the flange that was on the end of the stock down-pipe to the new down-pipe. It then bolted directly to the cat. I dont have to run a cat where I live so a 3 1/2 piece of pipe got welded into that spot. Looks like a stock set up. I still have a hard time believing that the factory puts that little flat pipe in there.

you welded part of the old pipe to your down pipe? that makes no sense, my down pipe only thing re used from the old set up from the factory was the clamp to the turbo

why didn't you just go straight to 4 inch the whole way back?

The stock pipe is 3 1/2 so why do I need to change it? My down pipe was 3 inch and had just a cut end. I welded the flange off the cat that took it up to the 3 1/2. I then removed the cat with the 3 1/2 pipe. I was able to use the flange joint and then I was able to use the hanger.

Thats the same way I do it, I clamp it though.
