Magnaflow 12579

Reviewed By Jeff T (Des Moines, IA) Reviewed for a 1999 Dodge Dakota —6/20/2017 3:20 AM

The 12579 is a large case single inlet, single outlet muffler. Internally the exhaust is split running the length of the case rejoining before exiting. The muffler has a nice quiet rumble at idle with no drone at speed. It has a nice performance sound when the throttle blades are opened wide. Install consists of headers, 2 1/4" to 3" Y-pipe, 3" through remainder.

2017 Silverado 6.2L Muffler Swap

Reviewed By RICKY H (SUMNER, WA) Reviewed for a 2017 Chevy Silverado —5/2/2017 6:35 AM

So happy with the new sound and so is the wife. You most def can hear it - but never is it obnoxious - not even at WOT. Just a nice mellow tone from idle to 75mph and no drone - no chopper sound - Deleted flapper. No difference in V4 around town or on the highway.... One big plus - now I can hear it shift - which helps feel it shift - before I hardly knew when it shifted. . Towed up a long grade - no drone - just a nice throaty sound even working it.... Cold & warm starts sound great!
