New! And some header questions..
Go to youtube and search for De Tomaso Pantera. Look for the race versions. They will have a true 180 header. Some are even with a single outlet. Well a lot of them are, but they have a "fake" dual outlet. It's simply a single outlet with a divider. But you'll get a real feel for how a true performance American V8 sounds with that type exhaust. I knew a guy in Macon years ago who had one. Had the Italian brand 180 headers on it with the single outlet. That car would make the hairs on the back of my neck stand up when it went buy. Unforgettable.
