DIY Exhaust

[96 3/4ton]

I have a 96 silverado 3/4 ton Ext. cab Long box. I recently cut the cats of (as they were plugged) and started putting my own exhaust on it. I am using 3" pipe. I am wanting to do straights up over the rear coming out the sides behind the rear wheels at 45 degrees on each side.

I was curious as to whether or not anyone could help me with the measurements to come up over the rear end.

I would have the stock pipe to come up over the rear end if the previous owner knew what they were doing with a welder as they cut the stock muffler off and stuck 2 pipes together in a "y" to go into the stock single over the rear end.

Any help is appreciated. I am doing this on my own for the experience and because I am on a limited budget. Which is why I could not afford the 2 cats at $200 each needed to replace the old ones.

Are you talking about what length of pipe you'll need? Do you not have the stock tailpipe? If you do then you can get a tape measure and see how long it is, and if you don't then i'm sure the junkyard will have one.

I am talking about what lengths and angles I will need. I do not have the stock pipe as mentioned above.
