hey can anyone tell me roughly the meaurments to make a 3 inch dump pipe from turbo to cat if it helps the turbo is a garret to4b

geez mate there would be alot of varables there, what type of car would be the first.

basically mate the turbo manifold and cat need to be on the car and work it out for yourself, not being a smart a*** but its not one of them things you can just get the measurements for unless some on here has the exact set up as you (manifold, cat, turbo), really needs to be fabricated to suit your application.

are you dion the fab work of a shop, give us a run down on what you doing mate i am kinda curious

im just mounting the turbo up and a few other things i guess ill have to drive it to the exhaust place with no exhaust lol
