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.

I'm gonna give you a positive an honest review on this exhaust I went with Roush exhaust for my ford because that they're affiliated , I was displeased with the drone and the extreme sound that came from it so I try to dampen it by using other products when I finally was able to achieve what I wanted to accomplish it ended up being Borla if I would of known this from the start I want to use Borla exhaust right away ,and I'm sorry I didn't . That's my story .

I now have a nice growl to my truck exhaust. I only replaced the muffler, no tail pipe and it is loud enough for me. Love the sound at startup!

I purchased a 2016 Mustang GT used which had magnaflow's competition series on it. I had a shop retrofit the street series 12229 mufflers on and the sound is much better for daily driving. No drone at 2k RPM like with the competition series - it was really bad. I highly recommend the street series over the competition series.

I wanted something that would be deep and a little louder my silverado but not wake up my neighbors loud. If you are looking for something like my first sentence said this is it. There is a little drone in the cab but you can turn your volume on your stereo up just a bit and it drowns it out. It has the perfect deep tone I wanted and the exact amount of loud I want as well. Great product!!!
