That's exactly what got me into making my own exhaust pipes, all it takes is a good band saw, a welder, stainless wire and J bends from summit and you will be pleased at how well you can do it yourself. Don't buy a chop saw, they don't work good, and use the Cutting and Routing Exhaust Mandrel U-bends tech week thread here on the HAMB.
I feel your pain, but from the other side. I have a shop and a pipe bender. I spend way too long cause I'm never happy with my results. Only time I can do a complete is if I lock myself in the shop when I'm closed.
What Chevfordman said. I use a bandsaw and a mig to fit, tig for finish. Couldn't imagine this any other way:
40 years ago, I met Bill Huth, Gerry's brother. Told of crowds standing around the prototype machine watching ... he said the adverti*****ts from the early '50s showed the dual sets as mellow, quiet, or rapper. The rapper mufflers were filled with gravel from the alley out back.
These are way past overkill, but I was thinking of designing and prototyping a CNC mandrel bender like this one: http://www.baileigh.com/mb-42cnc-r-eco A manually controlled hydraulic bender is nice, but it would be worth the money and space to have a CNC bender that can do production runs of tubes for things like model specific roll cages and stuff like that. And of course things like common engine swap exhausts.
Wish you were close your work looks professional I just sawzalled a $800 system off my girlfriends 28 whippet sedan total garbage. Looks like J bends and welding time.
I have one, but they only do "Crush" bends. I only use it for under car on cars that don't really show the underside too much. I use mandrel bends for headers or high end exhaust stuff.
