nice video, always seems to hard to get a good representation through a video just since the microphones change things a bit, would love to hear that truck in person

it definitely helps to listen with headphones or on a good sound system that can replicate the bass. Trying to watch the video on a smartphone or laptop computer will not be a good experience.

Sounds good to me

I liked it a lot. I won't remove my stock exhaust to install it but if I needed new exhaust I would order it without reservation just after watching your video.

my stock exhaust had 2 issues. A smashed tailpipe and the first resonator was partially clogged with cat substrate. I had to replace all of it.

Just a follow-up to this video and thread. It seems that the Dynomax muffler has "broken in" after a few miles and there is quite a bit of drone in the 2000rpm range when climbing inclines and such. Too much drone for me personally. If you cant stand any droning, then this isnt the muffler for you. I changed it out for a Flowmaster 60 series race muffler with the same dimensions and it fixed it right up.. Here is a link to that video also
