Russ,
I am considering the same engine upgrades.  Can you share a little more info about the exhaust and K&N filter?  Were they done while you owned the coach?  If so, do you notice any increase in power (boost pressure) and fuel economy?
Thanks

Bill,
Thanks for asking, Yes! The only reason I even considered changing anything was because my muffler was leaking and beyond repair, in my opinion, so we were at a rally and Major, can't remember his company name w/o looking at my records but M & H comes to mind, was there and I wanted to upgrade to K & N air filter that he sells and I had bought from him before for our Semi-Truck Conversion, so while talking with him about that, he says the best improvement in power and fuel economy comes with increased airflow through the engine including changing the muffler, also! I said, you must be a mind reader, as my muffler needs replacing also!
The next day, he & I replaced both and I personally felt the engine seemed more powerful and ran cooler and crisper, if you will, with those improvements. As far as fuel economy, I might have seen a mile per gallon, or so, but that was not my goal, I had plenty of power, as this Bus is a totally different animal at 38' than the full sized units, when you are pushing 20-30 tons down the road, fuel economy is not at the top of the page. Temperatures, performance and longevity of the engine takes precedence, in my opinion!
I believe the improvements were well worth the cost and would do it again in a heartbeat, the sound I get with the Jake on, going thru a tunnel is well worth it?, although my wife/navigator always reminds me of local noise ordinances, kind of reminds my of my youth in the seventies!

Someone is going to get a great Coach that will challenge any Semi-truck on any Pass in the Rockies, riding in comfort that ONLY NEWELL can provide!!
