The Harbor Freight bender is good for bending stuff like black iron pipe or galvanized pipe or mechanical tubing with at least a 1/8" wall thickness. I used mine to bend up a frame for a small down rigger for shrimping and plan on using it to make a homemade gokart frame for the kids this spring. Better to find a good exhaust shop that you can drop the truck off at and bring back if it rattles or leaks.
