Exhaust, What to do?

[Fireman]

Hawkeye,



An Aeroturbine is a muffler. I have one with a full 4" exhaust. On the + side it really helps with egt towing. I tow a 11,000#+ 5th wheel, with my exhaust and a Scotty III intake the highest egt I've seen is 1050 deg. This makes me very . Driving around it has a very nice mellow sound, but under a load it gets a bit loud especally in the 1900-2000 rpm range. I plan to ad a straight through muffler to tone it down some.

It seems a couple of the best options we have tried with third generation truck is the Banks Monster exhaust that replaces the elbow, Aeroturbine with 4" down pipe and Silverline. Recently we installed a Silverline single exhaust on Jeff's 2004 and it sounded pretty good, but did have the drone at 1,400rpm and again at 2,200 rpm so we cut the down pipe and inserted an Aeroturbine as far forward as we could. The results were amazing, the drone is gone, the truck runs smoother and Jeff notice a performance increase. This combination also gives an excellent mellow sound with deep tone.

Gut the stock muffler, lol it's free!



Sounds really good outside the cab and not even noticable inside the cab with the windows up. Gives kind of a chambered/resonated sound, deep and throaty. I've had compliments on the sound. RBatelle has heard it, ask him what he thinks?



I did this before gages, but I'm betting that gutting a 4 pass muffler made flow less restricted!

How did you gut it? Do you have to cut it open, and weld it back together, or is this something that can be done without a welder?

I used a band saw and a TIG machine to complete the task.



People say they like the way it sounds, but I would really like it to sound like the old trucks!

Too much work???



I could gut a stock muffler and have it back together before you could replace the stock exhaust sysyem with an after market unit!
