Anybody run a single 3 inch exhaust?

I had to whack up the exhaust on my crew, reworked the rear shocks and a c notch so the tailpipes had to go. I am considering a 2 into 1 flowmaster with a 3 inch tail. Thoughts? Current setup is 2.25 headpipes with an x pipe into dual 2.5 flowmaster and 2.5 tails. Jay

They came stock with 2 3/4" or 7/8, so would think you be fine.

I built a 2.5" to 3" single exhaust for my truck



front pipes are 2.5" into the junction then 3" to the muffler (Walker Quietflow SS) and a 3" tailpipe over the axle to behind the right rear tire
