    I race a street stock division out on the West Coast. I can't seem to get much help from the people at my local track. Thought I would reach out here.

    Some guys are running mufflers and some are running open exhaust. We are required to run exhaust manifolds. I have heard a muffler can create some back pressure thus creating more torque. Any thoughts
