Great fitting kit
Installed this on my 1969 suburban. small block with shorty headers. Fit perfectly and sounds great. My last system had a bad echo inside but this one is so much better. At idle is has a nice rumble. As a note two of the 4 types of rear exits in the kit don't clear the spare tire well on the suburban or my hidden hitch. I used the ones that point to the edges of the rear bumper at about a 45deg and fit perfectly. The last frame support had to be shifted back because of the fuel tank mounts so if your truck has a rear tank inside the frame you might have to adjust for this.

Sounded great!
I used this kit on a 63 C10...not what it was designed for. Plenty of pipe and bends to make a great looking kit work on my application.

Flow master exhaust.
I had to modify the exhaust pipes because the did not open the ends up to slip over the pipe in front of it. Luckily I have the correct tools to do that..
