Thanks Ron.  You would think there would be more consistency within models.  Oh well, so far, so good on mine.  I do smell maybe a little faint smell when I open up the engine but have not yet poked around  to get a better look.  Maybe in a few days after I finish the more pressing issues.  So far, just did the racor primary filer  R-15S and the transmission fluid change and ran the motor for about an hour total.

Ah... nothing easy. I removed the muffler riser today and it looks like I got a 3 pieces nipple'd riser similar to CD part #Z3055 (see picture). But, I do measure the extension closer to 3 inch. So, should I go with Z3055 with 3.5inch extension or Z4491 with 2.5inch extension? Or it really doesn't matter and both will work?

please post or send me a message re which riser you get and why, as I have a 97.  also, did you have to replace the exhaust flange?  and how long for various things.  think I'll have to have mine done, as I can do basic stuff but this seems over my head.  thanks.

Hi Mark (Captran), I got the Z4491 with 2.5inch extension. Did the installation this morning without issues. I did change the flane as well.
Now moving my attention to the heat exchanger re-install. Always something.

Francois : When you reinstall the HX just make sure that there isn't so much insolation that it presses against the exhaust riser.
