Thanks! :thumb:

So the DPF is also the catalytic converter? Interesting.

Actually, our US spec DPF consists of a 1/3 catalytic on the front and 2/3 DPF at the back. SCR catalytic is located in the middle of the exhaust, somewhere under the rear seat.

Very interesting. Have you looked at removing the DPF bits from inside the unit while leaving the CAT part alone? Put in a collector and then straight pipe where the DPF was (pack with glass wool or rock wool for sound deadening). . Then weld it back up (open from the top so it's less noticeable).

This way you're it's not a stink bomb and you're solid against anyone nosing around while still getting rid of the DPF bits.

The cat is for the CO only, it does not stink much

Thanks! I'm learning a lot about these.

The DPF replacement piece does look really nice. Good stuff!

Update

Odometer just hit 150,000 miles and have still had ZERO issues with this mod. Just drove from Wisconsin back to FL and averaged 23.1 MPG mostly at 79 MPH. At a steady 60 MPH it'll average 30.3 MPG. Still no issues with the transmission at 150K. I'll do a fluid change with Pentosin again next week since the filter/fluid change was at 100K miles.

Looks like egg on your face since I have 50,000 miles with this and zero issues.
