Gone are the days when you could just roll down to the local muffler shop with your specs on a sheet of paper and buy the pipe from them, then the guy would throw the required ten minutes worth of bending time at 'em for a half rack of beer.
Nowadays no shops can do anything because of "insurance" but they might still let you drop a grand to do it their way. That's if you can even find a shop that will do custom pipe bending work.
