Default 99 NBS 2500 ehaust

I'm looking for the stock exhaust size for my truck. I believe it's 2.5". From all my searching.

My wife paided to have my exhaust fixed along with tne broken manifold bolts (for my birthday about a year ago) after me procrastinating about getting it done because I was trying to save for long tube headers. She had true duals with a x pipe put in with flowmaster 40 series mufflers. Im wondering if they make a set of long tubes for stock exhaust size or not.

When I picked the truck up they told me one of the flanges from the original pipes was cracked and they welded it but wasnt sure how long it would last. Well the time has come that I have a slight leak.

Will get pics posted soon as im going to check the manifold bolts to make sure some of them are not loose and look for the reason of a dull thud when i hit a bumb.

Should be dual 2.5 into a single muffler with a 3 inch outlet.

Muffler is a dual in 2.75", single 3" out. A 3" piece of pipe usually fits right over the top of the 2.75".
