Review on Efficient SCITOO 3-Pieces Exhaust Pipe Expander Tool Set 1/18'' to 3-1/2'' – Ideal for Most Vehicles and Trucks by Scot Hughes

DO NOT waste your time buying, you won't be strong enough to extend anything beyond brass or copper. If you have a piece of pipe that needs expanding, just go to your local shop and they can do it for you and charge you next to nothing. FYI I bought this to widen the exhaust tip to match the exhaust pipe, the tip was even cut off and it still didn't widen it. complete garbage and waste of time.
