This might be the wrong section, but I was bored and and somehow crawled under my truck and saw what looked like three cats. I was just wondering if that's standard on the NBS Silverado. It's a 2011 4.3 V6
 
I meant here on the website. In the "About Me" section of the profiles it jumps from the straight six up to the V8

That I can fix.:cool:

I know some of the older v8's had, sort of, 3 cats. They called one a pre-cat, and the two behind it were cats. Don't know if they are still doing it.:undecided:



EDIT: 4.3l added

another edit: Everything I can find only shows 2 cats. One on each side, then the pipes join at a "y" and go on to the muffler then back to a resonator and then out.
 
Yeah it looks like it has the precats, and then after the y-pipe it has a third cat. Once I get my Mac back I'll upload some pictures.
And thanks for adding the V6
 
I had a neighbor's cat that got ran through the serpentine of my 90 Safari. Not a pretty sight. Had cat fur coming out of the vents for months! Not the type of cats your talking about though.
 
Ok so I took the truck down to the exhaust shop and had them look under and sure enough, there are three cats
