Started brushing up on my welding to get my exhaust system started. I bought the speed engineering builders kit. After planning it all out, I think I’m a little over my head for the equipment I have. Don’t really have a good way to make/fill in the needed pie cuts and still don’t have enough tubing to even get the mufflers where I want them. Guess I’ll be taking it to an exhaust shop after all. Oh well, at least my welder is fixed and I can do other projects with it.

Really all you need is a chop saw and a sharpie. Buy some straight pipe and a few mandrel bend J's or U's and you are good to go. It's usually less than $100 in piping even from a place like summit. Some times you can just go down to your local exhaust shop and buy the aluminized tubing direct from them or go to a local metal supplier. The mandrel bent U's or J's are a little trickier to get and you usually have to order them, but they are easier and cheaper to ship. My exhaust is already partly 3" and I already have mufflers, but it's kind of a mess. When I put the 454 in it will have headers so I'll be cutting off the patchwork stuff and using header buddies to 3" mandrel bends around the transfer case area with a H-pipe in there somewhere and then tied into the existing 3" after that. The mufflers and some of the piping will get tweaked and re-organized and then changed from an axle dump to side exit. I'm hoping to manage most of that with 2 J's and 2 4-ft lengths of 3" from summit since I'm already buying enough stuff to get the free shipping. I might go over to my local exhaust shop first and see if he'll sell me some tube first.
