I am not sure the 3" is correct for my 2-1/2" downpipe. Need to research more I guess.

Why are you using a Stinger system in the first place? Banks designed that system for turbocharging the NA 6.2 in the old body style ('73 - '91, such as the CUCV) and had a 2½" turbo downpipe to clear between the cab firewall and frame. A 2½" turbo downpipe will negate a lot of the power you're trying to get in this build by greatly reducing exhaust flow and increasing backpressure and exhaust heat.
If you're doing this motor install into a GMT-400 why aren't you using a 3" turbo downpipe, or even a custom 4" turbo downpipe that has been "squashed" into an oval shape to clear between the firewall and frame? If this install is into the '73- '91 platform, you should be using a 3" turbo downpipe and "squash" it into a slight oval to gain sufficient clearance.
Just my 2 cents worth.

Are you sure that isn't the "Sidewinder" you're referring to rather than "Stinger"? @Husker6.5

That's right. But, regardless, that should NOT be a 2½" turbo downpipe on the Banks Stinger system. Go recheck you're measurements and make sure you're not reading your tape measure upside down.
