Review on Upower Stainless Exhaust Muffler Straight by Brian Rogel

It had a chatterbox back that was too loud. Replaced the resonators with these. Sounds amazing! A very small drone compared to the previous one. Deep, pleasant sound. I had to "clean" one of them by hitting it directly on the seam with a hammer. Thought the welds would burst. I was surprised this wasn't the case. The muffler is a bit heavy, but that's probably why it took the hits. Incredible value. If you want a growl that's deep but not too loud, this is a great option.
