Review on Universal Exhaust Muffler Tail Pipe Expander Kit, Fits 1-1/8" To 3-1/4" Pipes, 3 Piece Set With Carrying Case - Improve Your Vehicle'S Exhaust System With GZYF! by Casey Vance

I know you get what you pay for, but all I needed to do was 2 pipes, summit brand pipes by the way, the tool shattered before even getting close to expanding the pipe to what was needed, it's a decent looking tool and it comes with spare o rings, but it will probably only work for you if you have a very thin wall pipe.
