great product

Very happy with this muffler. It sounds great and was easy to install. It has a slight amount of drone that cost a star, but all in all as a replacement for a stock muff it is great. Would go this way again if I did this mod over.

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.
