Downpipe Installation Pics
I thought these pics might help for anyone preparing to install a new downpipe. My buddy down the street and I did both of our trucks at the same time. The learning curve made a big difference. The first one took 3 hours because of fighting the cat. It just wouldn't come off. The second one took about an hour because it was already straight piped. I haven't noticed better gas mileage yet. Probably for two reasons:
1. It's colder right now
2. The first thing I noticed after doing this mod was that the engine revved up much faster(less turbo lag) so it's easier to stomp on the pedal. Little by little, I have been trying to lay off, because it's just sooo much easier to push those RPM's up.
Hope this helps
Cutting off the Cobra head - I recommend a good blade like a Lennox. I cut off two pipes with one of these blades. A lesser blade would have struggled.
Finishing off the cut:
The old flat pipe is gone!
Checking the fit after the pinch weld is bent back. After notching it with the sawzall I used a 2x4 against the engine block. It bent very easily. I just bent back the heat shield instead of cutting it off completely and I haven't had any problems with it making any rattling. I figured that was better than mangling the sheet metal trying to cut it off in that tight little space.
It's tight in here after the clamp goes on. I know a lot of guys recommend using the other type of clamp, but I just used the one that came with the pipe. It hasn't leaked after 2 months.
My engine seemed to be mounted a little farther forward than my buddy's down the street. You can see how mush space is left between the cab and the pipe.About 1/2".

What a difference from the old one:

Thanks, guys. I'm not a photographer, but I did have to take it as a class in Architecture school. I noticed for the longest time no one has posted pics of the downpipe install so I thought it would help since everybody asks the same questions about it. Seems logical, since it's the first mod everybody recommends.
Mooseman, I have had that "need" so many times that I have a pretty good collection of tools. I can buy and feel good about those purchases. I mean in the long run they save money, right?
