So I decided to import my own.

well,
a resonator is just another muffler really, it is not like a cat which can get plugged over time.
if it runs well then leave it alone.
but
it is your truck so ...
let me know if you see any change.

My HZJ73 was built in the first month of production, so later ones may have something different - but the pipe going into and out of the resonator was necked down to approx. 1.9" OD... about 1 3/4" ID.. The rest of the system is 60 mm OD... The x-sectional area through the resonator inlet/outlet is only about 60% of the rest of the exhaust system.

It looked like this before I removed it.

It's very easy to check..

dame the truck has a 10x cool factor comparing to an 80. i am stoked on the truck
