I looked on the Flowmaster website and it doesn't have the 96' Blazer under the Flowmaster Super 40 Series 2.50" list, but it's under the 2.25" list. Is that because the stock muffler is 2.25", so the site doesn't have the 2.50" listed? But the 2.50" should still fit, right? I don't see why it wouldn't. If I buy a 2.50 tail pipe I just weld the 2.50 pipe to the inlet, and the 2.50 tail pipe to the outlet.

 

Well, I'm looking at it listed right here, but it's offset inlet and outlet. Is that the way your stock muffler is made?

 

I dont know about the96s since theyre kinda oddballs, but mine is 2.5 in and 2.25 out. So if yours is like that then yes a 2.5 is what you need.

 

My in/out are 2.25, but my pipe going into my inlet is 2.50, using a reducer and welded to the inlet, the tailpipe is 2.25 and welded to the outlet.
But my in is off-centered and my out is centered.
I remember seeing that list now, because I knew somewhere it had the 2.50 in/out for my truck. I guess that means the 2.50 will still fit only I'll have to buy the centered outlet since I have that now.

Even that list doesn't show the '96 Blazer, although it comes up in the search results.

I'm buying a 2.50" tail pipe to match the rest of the 2.50 pipes for more sound.
