The loss of torque on a slant can't be any worse than a stock manifold. The thing has a 4 1/8" stroke for God's sake.:toothy10:

I bet this set-up is worse than a stock exhaust manifold. It would probably be about as bad as putting zoomies on it....the only way to find out is to send him some money and put it on your car. Be sure and get a baseline with the stock manifold and gives us a report.
