Part# GB-44 ~ Performance Weaponry group mandrel bends in 304 grade stainless steel allow you to custom make your own extractors and headers.  This part number is for single 1 3/4" inch imperial size tube bent to the shape shown in the picture.

Ideally you would probably need order a quantity to represent each exhaust port on you engine, for example a 4 cylinder engine you would probably need 4 of these group mandrel bends, for a 6 cylinder there would be 6 and for an 8 cylinder you may need 8.

The 180 degree bend allows for you to cut through at the precise angle you need coming out of the exhaust port on the head, either just past the 90 degree point or just under depending on your application. The rest of the bends that is left will give you what you need to complete your own custom made headers.
