[W126 Coupe] Exhaust system

[Gerry Van Zandt]

You need more information -- I'd have a competent (MB-knowledgeable) exhaust shop check the whole system out.  Generally it's the resonator (kidney) or rear muffler sections that go bad.

You can go two ways if you have a stock exhaust system -- go with factory parts, or go with a Timevalve (stainless) system.

Here is Timevalve's page for US 560SEC exhaust systems/components:  http://www.timevalve.com/cat/us/p19c2.html
Generally their stuff is of pretty good quality, though some parts I've heard about for other cars hasn't fit without some tweaking.  I think their quality has slipped some over the past 10 years, compared to what it used to be.

You have to call Timevalve for current prices.



For factory exhaust (if you want to go that route), here's the diagram:

The major components are indicated on the diagram:

downpipe / catalytic converter:  
part number 126 490 48 19
List price: $4,020
price from parts.com: $2,771.50


center "kidney" resonator section:
part number 126 490 58 15
List price: $390
price from parts.com: $269.10


rear "muffler" tailpipe section:
part number 126 490 60 15
List price: $530
price from parts.com: $365.70

You can get ONLY factory MB parts ordered from parts.com for less cost than anywhere else in the country (dealer cost + 15%) + shipping.

Hope this helps.
Cheers,
Gerry
