Magnaflow Performance Mufflers Reviews

Sweet Flow

Reviewed By mark p (San Antonio, TX) Reviewed for a 2005 GMC Sierra —10/5/2011 9:47 PM

Great product. Sound is distinct, and I like that. Purchased this because of the size, so it was easy to install myself. Appearance is well polished with engraved Magnaflow emblem. Would definitely recommend the product. Shopping experience is great as usual. Muffler is loud but not annoying, absolutely drone free throughout idle.

Flow master 70 series

Reviewed By Jeffrey S (Warsaw, MO) Reviewed for a 2008 GMC Sierra —11/10/2016 3:22 AM

I purchased this muffler to replace a smaller flowmaster muffler that was too loud for my application. This has the performance of the flowmaster technology without all the noise.
