Ginge !
its a custom pipe work so its going to cost no matter what. it all depends if he is using a cosworth back ex housing and wants to reduce down to his 2"/half ex .and another thing is it looks alot better if its made all one pieac and if he is happy with crapy hydrolic bends or proper madril bends that dont reduce as it sweps round on its bend makes a diffrence so if you add it all up the welding wire and the gas and the bends and time £150 is not alot of money at all my price has just gone up
