Quality engineered part

Reviewed By Cole H (Chicago, IL) Reviewed for a 2007 Hummer H3 —9/2/2015 3:53 AM

It's pretty simple. Rattle trap exhaust is now smooth reving, with zero loss of power after updated dyno. Only issue would be weight, pretty heavy part to add in. One of the ideas behind this Hummer H3 was to reduce weight and all lite weight exhaust just got killed back to stock weight with this installed.

I only have an inline 5 cylinder egine so I wanted good performance,sound and better fuel economy. Thats what I got with the super 10. It added a better sound and tone to the inline 5.

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.
