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.
