Muffler fell off! - Page 2 - PeachParts Mercedes-Benz Forum

F18 · #16 12-28-2006, 06:53 PM

Had taken my 98 E300 into a local Meineke about a year ago with the same problem. The owner there said that the way the rear muffler on a W210 is hung on one side puts too much twisting stress on the weld and the inlet pipe.
He sees them all the time with the inlet of the muffler cracked or broken completely off. He charged me $230 to fabricate a new inlet flange and weld a piece of angled metal between the back of the muffler and the inlet pipe to take some of the stress of the weld joint between the pipe and muffler. He said it is such an obvious design problem that the MB engineers should have made the design changes right at the beginning.

Mine is a NA motor. As far as I know, MB didn't make a TD in 96. The drone is driving me crazy!

Someone beat me to the punch on recommending a cherry bomb. Works great. The car is just barely louder. I can definitively tell you that boost builds quicker, acceleration is up, and the grin on my face is much bigger.

It has probably boosted my mileage by 1/4 mpg too

Well, I have 2 complete exhaust systems under the house, and one still on Scar. I guess it was a good idea to hold on to them. I have holes in the resonator on the wagon. Gives it a funny nasally sound.

NO notacable effect in sound

ok, if it is a straight pipe, why did you say you paid 30.00 for a gasser muffler?
and OP, I was quoting monomer's message about the turbo, I know you don't have one.

In the context of Mercedes, there's no such thing as a "good muffler shop" and there's no welding.

In addition there are no aftermarket performance enhancements, as a Mercedes is well-engineered in the first place.

Go to a dealer or a Mercedes independent and have new units bolted on like they're supposed to be.

Cobbled up cheapskate solutions only detract from your car's resale value and degrade its performance.

Most of us can't afford to buy our wives an '06 CDI, so we also have to cobble our exhaust together. I'm not sure an exhaust system with a welded in muffler has ever been a good bargaining point for me when buying a car......

If it was well engineered, why are they falling off after 10 years.
Your points aren't really that great.

Sorry about the rudeness, but Good Lord.......

You act as if technology hasnt changed in the 20+ years.

A dealer will usually charge more than the entire car is WORTH for a complete exaust. A weld job from a trusted shop is just fine.

Sorry

, but atleast I used your thread to do it.

I am reviving this thread to add my experience with a failed joint right where the pipe enters the muffler on my '98 E300 Turbo Diesel. I caught it before it broke completely apart as I had noticed louder exhaust noise lately.

My local custom exhaust shop fabbed up a new pipe from the center joint to the muffler and welded in at both ends to replace the pipe that had failed. Cost $160 and good as new, actually better than new as the OE pipe is clamped at the center and now it is welded.

I don't see why these should not be repaired rather than replaced. The new muffler from M-B is over $500 which includes the same piece of pipe coming out of it - welded the same way the new pipe I just had installed. The rest of the exhaust system is in very good shape so I just needed that one repair done...so we'll see if it lasts another 10+ years now.

That's exactly what I did. I bought some pipe from Pep boys and had a local shop just weld it onto the mufler for me. As good as new. I paid the guy $50 cash.

When my exhuast fell apart I replaced the downpipe myself with one from on-line (ANSA) then I had a shop add a new exhuast from the middle on back with a "truck" muffler. Problem is, it restricted things and my performance/mileage suffered a bit. Only a 2" pipe, which is smaller than stock. So I tore it off, went back and complained, and they made a 2.5" straight pipe to the back for me for free. Initially I paid $220 for the muffler/pipe they put in....and used it a little under a year that way. The straight pipe was/is WAY better, more power, more mpg's....and more sound!

I've only been pulled over once in the past year with it.

I coated it during the fall with about 6 heavy coats (2.5 cans worth) of rustoleum high-temp black grill paint from turbo to bumper....so it should never rust. It also makes working under the car so much easier with such a simple exhuast. Its supported at the turbo, the transmission, and with two hooks/rubber hangers at the very back. Thats it.

I'm waiting for my exhaust system to fall apart to I can "improve" it. The 240 shouldn't have me waiting for too long. Unfortunately, I'm pretty sure I'm going to have to keep some kind of a muffler on it, since I'm told they're really loud straight-piped.

I've heard a 6.9 International with straight pipes, and it sounded really good, provided you were 50 yards away. I also heard a 6.2 GM get run with open manifolds once. It sounded really good, but again I was about 50 yards away. We had a couple of straight-piped DT466 Internationals and N-series Cummins over in the sandbox, and they sounded great. The turbo quiets the exhaust just enough. The best sounding one was a semi-tractor with the Cummins and a stack made out of transport tubes for 155mm howitzer rounds. They called it "The Intimidator".

Mine fell off months ago, will never go back. Just loud enough to be a rude boy but not laud enough to get pulled over

My resonator did stay in place.

Thats what our 300D currently has. The muffler fell off, so we just added a downspout to the end of the pipe where it broke off and treated the whole thing with grill paint. Should last a long time. Its louder, but not a lot louder.
