What is the difference between exhausts made for NA and NB cars?

There is a sale locally to me for a enthuza turbo speeder exhaust, but its for an NB. Id like to know if its possible to use it on an NA and if not what would be involved in the conversion.

 

At minimum, the hangers are different. Which wouldn't be a big deal, but I don't know if there's anything else.

 

The example I have messed with also had the exhaust outlet for the NB slightly closer to the side of the car than the NA, but don't worry, it will melt itself a hole.

 

Dagnabit. I knew it wasnt gonna be simple.

 

It never is. There is always a deal, and always some small annoying reason it won't work.

 

i believe the OE NB exhaust is actually two pieces - a midpipe with integral cat, and a muffler. They might be selling just the muffler.

 

Isn't the NB midpipe welded to the cat making it impossible to do a bolt-on cat-back?
