I am replacing the rear muffler on my 1990 300E with an OEM muffler from the dealer. I am going with oem because I like to keep the car quiet. The cost ($297) is actually cheaper than aftermarket ones like walker.

I am going to go to a muffler shop and get them to put it on.

1) Should they just cut off the rear one and clamp the new one on? Are there any issues if they weld it? Wouldn't that be better, so no chance of leaks? Because I read on some other posts that the exhaust should never be welded and I dont understand why not?

2) I want to add 2 chrome tips. So some custom work would be required once I find some tips that will work. Any issues here I should be concerned about?

3) Do I need to buy a new clamp and the 2 rubber rings from MB? Can I just re-use the old ones? Would the muffler shop have these for my car, or do should I have them beforehand (if I do have to install new ones).

thanks guys.
