Summit or jegs exhaust

I used the Summit 2 1/2" kit on my '65 Valiant 318/904/Spit Fire Header combination. From the get-go it is a cut and paste situation since the "kit" is designed for '67-up cars. I have been told that the early A cars are the same as the '67-up cars from the transmission cross-member back, which is why I chose this kit. The drivers side was not so bad since that is where the stock exhaust went but stuffing a 2 1/2" system down the right/passenger side was an exercise in futility. It is A) in there but B) it ain't pretty. I can not imagine stuffing a dual 3" system under an early A car unless the stock fuel tank has been eliminated and a fuel cell is mounted in the trunk. Sorry, no pictures. Would I do this kit again? Probably not considering how much cutting and welding had to be done. I think, if there is a next time, I would simply start with some mandrel bends and probably 3 sticks of 4' straight tubing. Cost would be roughly the same.
