Everyone thought it be loud and obnoxious so they were trying to convince me to just settle for glasspaks.... And am I glad I didn't... This thing is MEAN and very aggressive since I got two coming out, dumped at the axle complimented with headers... I recommend these mufflers to everyone!

the 50 muffler is the right one for me and my sierra. it is just loud enough to let you know there is power under the hood, but it will not vibrate inside. unless you punch it, you would not notice it much. you can tell in normal driving it has more torque and horsepower.
