I had my local muffler shop bend 2 90 degree front pipes based on 2 crappy pipes and a cardboard sketch and measurements of what I wanted changed. He charged me $50.00 (the lowest charge he does) for what could have been a "No, we do not do custom work without the car" refusal. I haven't tried the pipes yet but he did do exactly as requested + throw in a couple of cast iron manifold flanges I could not find anywhere. If these pipes do not work, its my fault not his.
