Has anyone ever tried on of these mufflers. I kind of like my current setup but I'm more of a "Silence is Golden" kind of guy.
I was thinking that I could keep my current muffler (move it to the rear) and put the Donaldson towards the front.
Thoughts??
I'll have to run an adapter to fit the 5" to my 4" systems.

 

No body seen or heard of these puppies??

 

I too value a quiet driving experience...gives an opportune time for thought, eh?

When my stock muffler is ready for replacement, I'll be deleting the catalytic converter and going with a Donaldson muffler. The Donaldson model M090544 is a 51" x 9" muffler with a 4" inlet/outlet. Commonly used in many commercial trucks, it's available from Ryder Fleet Products for $88.14. [800] 759-6479

Good luck!

Ive got a Donaldson similar to the one you have on my first gen and I like it. its realy quiet and is really priced well. no complaints at all.

As for the silent partner I have never even heard of them but I am intrested. If you end up getting one let us know how it works.

 

the 101182 is a little quiter. add a m090072 in front of it for best results.

 

The 101182 is one of the Silent partner mufflers.
Here are the specs on that one.
The 101181 appears to have better flow characteristics.
See the specs here.

 

Well Ron...if I had to pay the quoted $324. dollars for a Donaldson "silent partner muffler" verses the $88. dollars for one of the top selling Donaldson mufflers, I'm afraid there would be little quiet enjoyment!

I might point out that the more expensive Donaldson "silent partner muffler" you mentioned is designed more for exhaust brake applications.

 

Yes it is quite a bit more expensive and they do refer to exhaust brake application but it is a direct replacement for a regular muffler. If the only advantage over other mufflers is silencing the jake brake then it's certainly not for me but if it reduces the exhaust sound considerably better than others while providing maximum airflow I might be willing to spend the extra bucks.

 

Still researching here.
I found this spec sheet on Donaldson's website. It shows size, Db attenuation CFM etc.....

I'm assuming that the higher the number on attenuation the quieter the muffler at least from this info.

Anyway there are higher attenuation choices but decreased CFM levels.
So what kind of CFM levels should we look for when adding a muffler to our trucks for maximum performance? I could decide to upgrade my turbo, add injectors, 3 GSK etc... so I don't want to overly restrict things but I do want to get as much silencing characteristics as I can.

 

Here is some info that I found in another post.
