Re: [Chrysler300] 300K Ram Muffler Specs?

Hi David,

As the club chart illustrates, the Ram K mufflers are the same spec as the J. Having just recently researched this issue for the J, I can report that the closest to correct muffler you will find is at Waldron’s Exhaust in Michigan. They offer three styles 1) OEM 3 chamber “stock” sound 2) “Mild Imposter” 2 chamber turbo style and 3) “Imposter” 2 chamber turbo style with a more aggressive sound and better flow they claim similar to a Flowmaster 40 series. Each are $80 per muffler for aluminized. The dimensions are 5” by 9&1/4” (actually 9&3/4” with the seam) with a 19&1/2” case and about 23&5/8” overall length with the inlet and outlet. They can custom make it with a 20” case length for no additional charge if you wish. It is the correct offset 2.5” inlet and 2.25” centered outlet.

I chose not to get them for my J as I reused my old pipes which are in good shape. I went the “frugal” route and got Walker SoundFX #17853 mufflers, $26.97 each at Summit Racing. They are two chamber mufflers with an 18” case length and 23” overall length (you only have about 24” or so space to work with under the car), 2.5” offset inlet and 2.25” centered outlet. I painted them with high heat aluminum BBQ paint prior to installation. The sound is louder than stock but a lot quieter in the car than the droning Midas turbos that were previously on the car. Outside the car they are quite throaty. Flow seems fairly decent, but without instrumented testing it’s a subjective assessment.

300ly,

Hi All,
The mufflers on my Ram K are bad and need to be replaced. The set currently on the car are incorrect and I'd like to have an OEM-spec system back on the car. Can someone with an OEM muffler please provide measurements on:

1. Muffler Length?
2. Muffler Width?
3. Muffler Thickness?

A reference pic or two would also be most helpful. The goal is to create a true factory correct reproduction.

Conversely, if a fellow member happens to have two NOS mufflers sitting on a shelf I'd be interested in purchasing them!
