Call NBS race car fabrication. In ST. Pete off 70th Ave and 49th St 727-541-1833 ask for Dave or Andrew, tell them Frank sent you. These guys know there shiat. They built the 2.5" mandrel bent exhaust on my soon to be turboed Swift. I will building all my other turbo piping there as well. They have a really cool AE92 Corrolla tube chassis turbo drag car there and a Conquest drag also right now.
