Aero Turbine muffler?

^^^ don't really want to be that guy

We had one on out previous coach with a 425 hp C-12 but don't know if it did anything. Yep, it was loader outside though still quiet inside...at least until the Jake was engaged on high than it really rapped. That alone would be worth the cost.

i was thinking of getting the 4040xl which is the one with the resonator (medium tone)
4"

Yeh, but these don't sound as good even though they perform just as well.

I was very interested on the Aero muffler, but after asking the question in this forum I changed my mind. It included a special air filter and the muffler which they were selling at the FMCA rally in Indio, CA a couple of years back. It saved me around $1200.00

Actually all my coach needed was to change air filters from the original which was a Farr to a Racor. As soon as I changed filters my coach has a lot more power going up long steep grades. With the original Farr and the Wix later on the vacuum gauge would go right up like if the filters were plugged up even when new. With the Racor the vacuum gauge works perfect below the condemning line.

You can buy a SpinTech 5" in and 5" out for $165.00. This muffler will not drone and may or may not be to loud for you but it will give you the best flow available and is not $1200.00. Their performance muffler when tested on a 410CI sprint car engine had no negative effect on HP or Torque.
