Nah, look at the diameter of the neck down at the factory "Y" pipe. You think going from 3" to 2" is going to make a bit of difference after that?
Actually, without putting it on a dyno they can't make that statement. Going from a wider pipe to narrower (within reason) can often act to scavenge gasses from the manifold faster. How do you increase water pressure and the speed which water travels through pipe? Same principle.
Now I'm not saying there won't be a CFM decrease with the neck down, but even if there is, going from 3" to 2" for about a foot and a half isn't going to make enough difference to be able to tell anywhere but on a dyno...

so if it drop the torque curve a little lower will it be better for offroading on sand and climbing sand dunes and extreme hilly roads ? coz i go with my brothers and friends offroading and they got jeeps and avalanche z71 and silverado and sierra 5.3 and sometimes i cant keep up with the avalanche on hilly roads ,,,, So i need ur advice HammerZ71 Please ,,,
Yeah, the name of the game off-road (or towing or hauling for that matter) is low end torque, you can have all the high end HP in the world and it'd be pretty useless to you, and yeah, I think I'd find me another shop, they don't know their a$$es from a hole in the ground...

I wouldn't say it's better from a performance standpoint. Unless you are comparing a really restrictive muffler to a really good flowing one, the difference is not going to be felt. NOW the GlassPack will sound better for sure.
The shorter the pipe run, the louder/deeper the exhaust note will be...
