I just replaced the exhaust system on my '95 E300D. I purchased a
new replacement rear muffler, and intended to keep the cat and bypass
the resonator with a custom pipe. Once the old system was dropped
(original system with 199,000 miles on it - repaired several times by
previous owner), it became evident that the cat was not easily
repairable. I couldn't afford to shell out the $900 or so (street
price) for a replacement cat, so I made up a custom Y pipe and tied
it into the new rear muffler. With almost 10' of straight pipe
before the muffler, it is EASY to understand the purpose of a
resonator. I have seen a marked improvement in performance,
especially at the upper RPMs, but I now get the dreaded "angry vacuum
cleaner" sound under full throttle. I am planning on installing an
inexpensive glass pack midway on the pipe to resolve this. All in
all, I am very happy with the results.
If anyone is interested, I will post pics at
www.wrxtra.com/Misc/Automotive/Mercedes/exhaust sometime today.
And, if anyone wants to know, this is of course a racing diesel that
is off-road only, so I do not need the cat anymore...
