i want to make mine go straight up and out. ive seen where they take a header flip it over and put like a 6 in round chrome tip on it , i think there called tight fit or block headers. searched on ebay and they want like 110.00 for them. and the pipes are like 50.00. so iam trying to figure out what regular exhaust manifold i can use upside down and with the exit go stright up. one guy told me to find ones that go on some 327 s. any one got any ideas.
