I love my Super 44 series Flowmaster muffler for my '15 GMC Sierra!! Sounds great! Awesome throaty tone! Big savings compared to else where!

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!
