For those of you who build your own headers or exhaust systems, I would highly recomend buying from these guys---www.performance-curve.com/. I'm using their mandrel bends for the exhaust on my pickup, 2 1/2" aluminized steel tubing. Product is first rate and their service is the same...

I think Pat might have told me about these guys? Anyway, whoever it was, thanks for the heads up!!!!!
