i am installing a set of long tube hooker headers and getting a custom 3" y pipe made up. i can go with compession bent pipes or mandrel bent pipes. i know that the mandrel bends is the way to go but he said that the price of the pipe is going to double the price. is it worth the money to go with the mandrel bends. just for some specs on the motor. its a 383 stealth ram, afr heads, comp cam w 1.6 rr.
