Hello everyone

I read on this forum that the Tesi-3D catalyst is in two places: the bulge in the exhaust pipe under the engine, and the cross pipe behind the engine. Is this true?

Recently, I had my exhaust gas measured for a car inspection, and the concentration was different at the left and right silencer outlets.

To confirm, I prepared a USB endoscope camera and removed the silencer and exhaust pipe.

There was nothing in the cross pipe, it was hollow. The bulge in the exhaust pipe under the engine on the horizontal side contained what appeared to be a lattice-shaped catalyst.

This is thought to be the reason for the difference in exhaust gas concentration on the left and right.
My TESI-3D is the 11th limited edition registered in Japan.
