1997 C8.3 Mechanical - Would 4" Aero Resonator Be Worthwhile???
Greetings - I am once again contemplating ordering and installing an Aero Turbine brand 4" resonator for my 1997 Fleetwood American Eagle coach that has the purely mechanical C8.3 Cummins engine and am curious if anyone has any first hand experience to share. My C8.3 has 4" exhaust piping so I would purchase the Aero 4040XL. Wondering if the Aero has less restriction than the OEM Donaldson muffler, and would then lower exhaust gas temperatures and improve performance. I do have a pyrometer and boost gauge already installed. My current maximum boost is 22. THANK YOU, Jeff...

I installed the 4" on my MH. Did not have an egt when installed, have driven it around 13000 miles since install. I now have an egt setting here and waiting for spring. It makes a lot more noise, I even open the drivers window sometimes to hear it. My original muffler was a straight through from the factory. Other than the noise I can not tell any difference. Other have made claims of improvement. I only paid a little over $100 for it so nothing lost.

If you were well tuned into your engine, you would notice quicker acceleration, less heat in engine area and faster on grades. That said, sone folks could notice a 25 hp gain, while some would not notice a 200 hp increase.

Some people also have a good imagination.

DAJO,
Boy are you correct on that account, at the same time I am amazed that since you had a straight thru muffler, WHY would you buy a resonator ?
Surely no improvement on exhaust flow, reduced temps, back pressure and faster turbo spin up etc, So I under stand why you can not detect any difference as there is no difference between straigh thru muffler and a resonator, except the resonator lowers the harshness a good bit.
Actually, never have seen a NEW straight thru muffler, maybe someone ran a pipe thru it to open it up ?
In the real world, everyone that I know of who installed the resonator have been very satisfied with the noticeable improvement, NOT imagined.
Some remain clueless by choice

Banks brand gauges. They make one specifically for motorhomes as it comes with a 55 foot temp probe lead. Don't buy one without a long enough lead as that wire CANNOT be spliced.

I ended up replacing my muffler with a straight pipe and the difference is nothing less than amazing!!! Two extra pounds of boost and no less than a 150 degree reduction in my exhaust gas temperatures. DW and I are on first trip since installing and after 200 miles I had to tell her what I had done as there is no noticeable sound difference inside the coach. And my coach pulls with ease as never before. Just wish I had done this very inexpensive upgrade years ago. Truly a night and day difference for less than fifty bucks!!! Have only driven 600 miles and have not refueled. That will be interesting. Dave M - I believe you are also on Foreforums. Your posts there also encouraged me to give it a try. Again, so glad I did!!

JD956,
Yes am on the Forefourms some also. My experience of the straight pipe vs the resonator is based on using the 8V-92 DDC, with the resonator, the exhaust note was very noticeable less harsh and was did not change the power feel at all.
That is why when I purchased the Foretravel with the ISM500, the change from their restrictive very quiet muffler was also very noticable, the first time I drove it was towing my 04 F150 on a familiar grade, the improvement was nearly shocking. that was about 3 years ago, today it is the new normal. Yes nothing bad about it and love the benefits it provides.
Cheers
Dave M
