I have a 1966 FLH which is pretty much stock and am replacing the exhaust. Purchased a new stock like 2 into 1 exhaust system made by V-Twin manufacturing. The problem is the end of the front cylinder pipe will not line up to slide into the 'squish pipe' opening. No matter how much I play around with it the two openings are about an inch off. I tried another front head pipe but got the same results.Any idea what may be the problem? All their tech guys said was to send it back for a refund, but need the exhaust installed. Can I just have a muffler shop bend the tube a bit? Would be an easy install and should line up you would think. Thanks.
