Review on 🔥 Muffler Glasspack 1.75" Inlet/Outlet - High Performance Exhaust System, 14" Overall Length by Carl Henderson

It would be a home run if it did. The "holes" in the can were cut out at the factory. The photo shows that none of them are open. I made a "tool" out of an awl and a piece of rebar that could reach all the dimples and hammer a hole there. I read a review that said these "mufflers" didn't do anything about the exhaust rumble. My money says it's because all the holes were sealed, just like mine. If I just wanted a pipe instead of a muffler I wouldn't order them.
