Exhaust Pattern, those with aftermarket exhausts- help needed Options

[beno]

Does anyone have a pattern for a 3" celica st205 exhaust piping?

I want to get some stainless steel tubing mandrel bent to fit on the end of a down pipe but the dude
said itd be better for him if i had a pattern for them to bend the pipes to.

Do all afternmarket exhausts follow the same path?
Does the type of material do anything for performance or just interms of quality?
Is there any difference between cruch and mandrel bending?

Thanks in advance

Your best bet is to get a bunch of bends (U-bends) that are pre-bent and have the shop cut and weld them together. No place that has a jig for building an ST205 exhaust would another shop borrow it, and just going off somebody's random pipe would probably lead to problems.

Other than getting over the front crossmember, the exhaust run is very straight and easy (run it under the rear axle).
