Time for a new muffler for the w123 300dt - PeachParts Mercedes-Benz Forum

Guys, I was pressure washing the undercarraige the other day, when i noticed a bit of rust on the area where the inlet pipe of the muffler meets the muffler. No holes yet, but i guarantee this muffler's time has come. Guarantee that if I take this muffler off and shake it, it will be like a giant Maraca.

So I was looking into mufflers online. The size of the OE muffler, for your refence, is 24" long, about 7" tall, and about 8" wide, with an inlet and outlet pipe of about 2.25" inside diameter. I looked into all the major brands of muffler and through all their models, and I found only one muffler that's about the same size, that has an inlet pipe of the correct inside diameter.

Magnaflow 13760:

It's under their 'XL Turbo Muffler' category--most others are much shorter. What would you think of this muffler, with the original muffler's hangar hooks (or generic ones) welded onto it in the right location, and maybe some DTM style Magnaflow tips, like one of these:

thoughts? flames?

this thread is so cool i replied to it myself. yeah...so i got the muffler in the mail today. it's literally the only muffler out there that's the right size (other than OEM eberspacher from MB). now i've got to decide whether i want to go with polished upwards pointing square-to-oval tips, or round chrome downward pointed tips a la lowrider style. the tips magnaflow sells are 8.25" long overall length, so they would end off about an inch past the bottom of the rear bumper. the tips are gonna cost me more than the muffler did.

And it doesn't matter which one you go with. They will all look out of place on a W123.

haha, i can't resist. i look at this car, and i keep thinking it's a 190e, and we've somehow gone back in time to 1988, to the dtm years...

That muffler looks good if you can get the brackets welded on without creating holes or weak spots in the housing. The only way to really tell is cut out the old one and hold that one up under the car.

That particular tip will really "soot up" the back of the car. Turn downs would be better.

I actually cut mine out of the system and have a straight pipe where that muffler used to be and put a black turn down on there. It is still pretty quiet without it. Just a bit of drone @ 70 MPH. Some people like that, I don't. But, it is good enough for now.

Yep... I concur, that is a "300 D".

Who needs a muffler at all, why not just a manly 2.5" pipe right from the turbo to the bumper, unimpeded!

That is what I have on mine.

you know what, that's what i thought after i installed this muffler. i though, this is a magnaflow, my car will sound like a camaro ss. right? wrong.

ZERO difference in terms of sound
