Welcome to MBc. About the extra length of tubing...I think it is all gonna depend on what sort of tubing it is, and what sort of seal you have on each end. It reminds me of the Dodge Muscle cars with the "Ram Induction 4-bble Carbs". It sure worked for them. But, they were precisely engineered manifolds. What you have is a similar set-up. Lord only knows if it will work or not. If it does, you will see a significant boost in power and HP...if it doesn't work, the last thing you will hear is a loud 'hissing noise' from the leaks around the connections between the tubing and metal before the final ball of fire hits between your legs. Good Luck. And again, welcome to the MBc.
