I was worried about getting the straight pipe because it might be really loud and annoying. However it was not. It was slightly deeper of a pitch inside the cab. I could hear the turbo whistle a lot better . Outside the cab the sound was mean and deep, but again not too loud at all. I am getting 1-2 mpg better and I can notice the increase in power. The only negative thing I would say is the instructions Diamond Eye sent are absolute junk. I ended up throwing them in the wood stove and did without them.

The previous owner of my truck had a hacked up OEM exhaust with an axle dump. The exhaust system seemed to have a lot of restriction so I was in the market for something free flowing.

This exhaust caught my eye and it was an easy decision especially coming from such a great supplier. Easy install, straight forward design, and really woke the engine up with the ability to breathe better. Sound is fantastic and really gives an aggressive, but not loud, tone.

I would highly recommend to anyone looking for an exhaust.

Unfortunately the hangers didn't line up like they should not did it avoid the crossmember for the transmission very well. I added 4-22.5 degree bends and all went much better. I have a 2002 F250 single cab. I would buy it again but knowing I would have to modify it to fit.

Came as described. Everything fit perfectly

Everything fits perfect.. take your time and have an extra hand there to help install downpipe.

Awesome exhaust for the money. Easy to install and fit perfectly. Plan on cutting down one strait piece if you are installing on a short bed. All the hangers come with the kit and fit good. Sonds great also!

Great sounding exhaust fit perfect. Hangers all went right where they were suppose to with good tough quality. Highly recommend this system to anyone wanting to straight pipe their diesel

sounds great you can't here it much in the cab when the windows are up. took me and a buddy about an 1.5 hours to install hardest part was getting the old one out.

Love the exhaust! It was easy to install and sounds great. Turbo spools easier then with my stock exhaust as well no restrictions
