Is the 1999 S10 muffler the same as the 1999 Blazer LT muffler?
 

I'm looking for a Super 44 muffler for my 1999 Chevy Blazer 4WD but everywhere I look it doesn't show one that supposedly fits it. I've seen some that fit the 1999 S10 pickup and to me it seems that both are exactly the same. Can someone tell me if the Super 44 muffler for the S10 pickup would fit my Blazer?

Here's the link in case it makes things easier. It's the S10 pickup super 44 muffler:

Flowmaster® 942446 - Super 44 Series Delta Flow? Aluminized Steel Muffler (Aggressive Sound, 2.25" Offset Inlet / 2.25" Center Outlet)

According to RockAuto, they are different p/n's

Never heard of the website but I checked it out and it was a HUGE help. Thank you.
