Re: Question about exhaust tail pipe size.

That's good to know. So I guess it was with the Vortec they went dual to the muffler, which was '96.

The dual tailpipes I had run on my '95 rotted off and the muffler is looking rough so I'm looking to do something with my exhaust, too. What I really want to do is run true dual pipes all the way, because you still can on these Suburbans.
