I would say over the frame is helpful.

wow this is hot topic huh. thanks for all the replies so quickly. my header is back ordered and wont be here for 6-8 weeks even though the website said it was in stock. ill call cx on monday and see exactly whats going on with that. reading all of this and seeing some pictures, ill go over the frame. i want stock-ish sound, i do not want a loud/rumbly exhaust tone, so id be happy to replace my entire system with original stuff.

could i use a stock 93-94 over the frame muffler assembly on the upturned header mid-pipe on a 95, is there a difference in the floor?

There isnt a difference in the floor pan but you will be missing a heat shield or two since different routings got different shields. I am over the frame in my 97 and dont notice it causing any ill effects.

The quiet flow muffler I used is very...well.. quiet. Does not sound any different over the stock system I took out and it was less expensive than a stock replacement. About half the size and weight too.

All I have seen is the 2' of down pipe off the exhaust manifold used. Im finding the 105 down pipe hard to located and pricey. Not sure Im willing to send $$$ to the middle of nowhere and hope.

Does anyone know if the FZJ105 exhaust manifolds are the same as FZJ80?
In Australia running a turbo 1FZ use the diesel 3" exhaust which runs inside the chassis rail, i would like to run my 1FZ exhaust inside the rail as it would eliminate all the bends to bring it back over the chassis and keeps it tucked up out of the way.
Also easier to build sliders.

Yep. Mine is from a 93/94; it’s nice to have it up and out of the way. Andy’s truck didn’t do so well at the hammers, but it was a gutless pig before we went and still was on the way home, albeit with a bit more whistle than it had before.

Folks keeping both stock cats and still getting over the frame rail with no body lift?

I seem to break my exhaust mounts and squish the pipe that goes under at least once a year now :/ Gone through a lot of bailing wire.

ive pretty much decided to get the headers with the up turned pipe(for over the frame) and build the rest of the exhaust system myself..
