Flowmaster Super 44 Series Mufflers Reviews

Flow 44

Reviewed By Mark H (ANTHEM, AZ) Reviewed for a 2011 GMC Yukon —10/29/2015 10:11 AM

Had a magna flow on muy Denali w/ 6.2 liter . So glad I changed it out with a flowmaster super 44. Now it sounds great and seems to be getting better mileage as well.

Flowmaster Super 10 Series Mufflers Reviews

Best $140 I ever spent

Reviewed By Bryce Z (College Place, WA) Reviewed for a 1979 GMC C/K 2500 —8/13/2015 8:32 PM

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!
