One of the things that really made me shake my head about this truck was the exhaust system. It was cobbled together, a couple of times, no joints and mismatched pipe sizes. And one really gross adapter that took the stock pipe size and shrunk it down to about 1.75" to go into a tiny muffler. It made no sense.

I ended up having to remove all of it, with a sawzall, and throw it in the trash.

But it did dive me a reason to run a true 2.5" system all the way from the collector to a nice Magnaflow. Which sounded great, and my wife hated it. It was kinda loud in her defense. So the Magnaflow came out and we went to a more stock style muffler to which I added appropriate sized inlet/outlets, still lots more flow than before, but less decibels, and a happier spouse. Happy wife happy life...

Lots more air moving thru this
