Welded Exhaust-2rz?

I was looking under my truck at something else & saw 2 things:
Shifter turret is leaking (needs new boots/bushings)

The exhaust looks to be all welded together from header pipes all the way bank, inc. cat convert.
There are ZERO flanges other than the one at the engine itself.

Is this normal?
Or did a previous owner of my truck have it all welded up at some point?

I ask as I was looking at LCE for a header & it looks like I’d need a flange welded in to install one.

 

Being a 95 I would venture it was replaced at some time.

Your sure it is one solid piece welded with no clamps?

meaning it was welded in place .Kinda hard to install a complete exhaust system .

Maybe the Cat is just welded in which happens when a universal one is used instead of a direct fit

 

No.
