Re: Question about exhaust tail pipe size.
The earlier years of these trucks ran a "dual tailpipe" exhaust. They were all 3" after the y-pipes, as far as I know, then the dual tailpipes used a 1 into 2 muffler. I don't know the diameter of the dual tailpipes. Tom said 2.25". I run a 1 into 2 muffler (3" in/2 1/4" out) with dual 2 1/4" tailpipes on my '95 Suburban
