If anyone saw TNN "trucks" this past weekend 2-9, they did a exhaust system that was rigidly attached to the frame, and connected to the headers with a stainless flexable hose looking connector. I'm not quite sure of the construction, I found one that looks simular at nickson.com. The idea I have in mind for my exhaust would make it easier to tuck out of the way if I could fasten it directly to the frame. but i don't know how well these connectors hold up, I've never used anything like them. does anyone have any experience with these? good idea bad idea? thanks in advance.
