Review on Enhance Your Exhaust System with Qiilu Tail Pipe Expander Set - 3Pcs Exhaust Pipes Muffler Spreader Kit by Quartreal Eagleman

This kit fits some pipe sizes and deserves three stars. The remaining two stars have been removed as the kit cannot round the largest pipe size given in the description. Forget using it on 3" pipe, no matter what the manufacturer claims. When the tool expands to the required 3" ID, there is no adjustment left in the tool and the individual reamer segments fall apart. Useful for 2 3/4" OD and smaller tubing.
