Exhaust sytem for 65 c10 with 327

[mrdave03]

I'm wondering if anyone knows of a decent place to order a bolt on exhaust system for a 65 c10 with a 327 with the drop down ram horn stock manifolds. I've seen one or two web sites but they note not for straight drop manifolds.. I'm confused. I'm looking for a dual pipe system and want to add my own flowmaster super 44 mufflers to it. I'm thinking someone must make a pipe set that will simply bolt onto the stock ram horns and be bent to fit the underside of a 65 c1o.
