You might want to talk to Brett. I think he put long branches on his 68 vert and was able to use the 2 1/2" pipe with his braces. Not sure exactly how. I bought the PY 2 1/2" downpipes and the only problem was the right side pipe had a little too much bend in it. Might be specific to my car because it's been lowered and has solid body bushings witch changes the body to engine fitment. Nice pipes tho.
