Review on Dynomax 24234 Race Bullet Muffler by Jay Arnold

Installed two of these on my Pontiac G8 to reduce my exhaust rumble. They really work by reducing annoying hum frequencies from your exhaust and eliminating the exhaust harshness and tone. It has a nice deep tone that's more like the exhaust note you hear than the annoying internal drone frequencies I used to have. I would say it removed 80-85% of the drone I had. I use two of these in combination with a Magnaflow Tru x Resoned X Pipe Mid silencer.
