Its been a while since i've posted, but the last couple of months have been extrememly busy for me. I have accomplished some stuff though. I've been doing some welding on the box. I recently moved it from my house garage to my fab shop so i can take an afternoon and try and finish it good enough to bolt on the truck and let the body guy to take over. I almost have my exhaust finished. I fabbed custom stainless mounts and hangers and got the stove pipe tacked up and sitting in place. Now all i have to do take it back down and doo the final welding, which will only take ten minutes of so. I'll get some pics as soon as i can for you guys. I also have been doing some minor wiring clean up. hopefully more updates and pics soon.

 

Heres some of the pics i promised. The exhaust pipe is made out of 3 1/2" stainless steel tubing (with about a 16 ga wall thickness) and a piece of 3 1/2" stainless steel flex pipe. The flex attaches to my custom down pipe and gets me over my tranny crossmember and then flexes down so the rest of the pipe clears my t-case crossmember.





I fabbed the hangers out of 10ga ss.





I removed it from the truck last night and i'm headed to the shop today so hopefully i'll get a chance to finsh the tig welding on it and get it installed for good.

 

Nice build, great fab work.

 

Nice job. Where did you get the SS flex from? Are you adding a muffler or going straight pipe?

 

When I put the floors in my truck cab I found 0.023/0.025 was the wire size that worked best for me. Cleaning the old steel of rust or debris helped considerably. I used to wipe the steel down with acetone to remove any greasy film from the old and new metal before welding.

 

I found the pipe and the flex at one of the local scrap metal yards. sometimes its amazing what you can find when you dig in the stainless steel bin. I think the pipe (which was 10' long with a swooping 90 on both ends) and the flex cost me 50 bucks. Its going to be straight pipe for now. i was amazed at how quiet the cummins was with just the down pipe, i can't wait to hear it with the complete pipe on.

 

oh ya, and the pipe is finished so all i have left to do is bolt her in place.

 

Man I WISH we had a scrap yard around here like that. I'd LOVE to find that at scrap prices!

 

Just luck. I think that someone scrapped an automatic carwash or something. My friend actually called me and told me they were there. He found and bought the same pipe and knew i would want one as well. He's actually builing a cummins crew as well. I found him a 78 crew F350 (long box) and hes done a 4x4 and cummins swap as well. He used a dodge front 60 and drive train. He has the best luck at the scrap yards.... hes found at least 4 front dana 60's.

 

I was going to install my exhaust tonight, but realized that the only 2' of frame that i haven't painted yet is right where the flex pipe sits so i want to splash some paint on there first. Hopefully get at it this weekend.

 

X2...Maybe I need to look at stuff other than trucks when I'm there.

 

Got the exhaust on finially. It sounds good. Heres a little video.

thats the best sounding cummins i have ever heard.

 

X2 ^ im so green with envy. Great work man!

 

Do you have anymore info on his truck. Did he use the passenger side drop Dodge dana 60 and drive train? Isn't the Dodge dana 60 like 2 inches less wide? I am going to do the same swap so I am curious.
