That's exactly what the inside of a Magnapack looks like. What makes the different sound?

Quick question, why did you go from the 2005 2500HD to a 2004 F150? Obviously I like the F150 way more, just curious.

Thank you. I like to show off my trucks details and sound now and then, and I like to capture it in every day scenario's and a little more.

The 2500HD just wasn't for me, was usually always getting it fixed, paying $710 a month for it, getting 11mpg, the work I do doesn't really require a 3/4 ton and I really do not like Chevy, so once the warranty expired I got rid of it and got my F150 because I trust an out of warranty F150 more than a warranty'd Chevy. And what has my F150 ask for? just a fuel filter, battery, gas and oil

Magnaflow packs every muffler with Rock Wool which is a tighty packed material that aborbs sound strongly, usually exhaust heat over a couple thousand miles burns the rock wool around the preforated pipe and helps it sound louder, round bodies it will happen in no time with the less packing.

Dynomax uses something else inside their mufflers thats not as strong as Magnaflow's rock wool. The rock wool helps dampen sound outside and inside for less drone, but Dynomax focuses on the deeper note outside rather than drone.
