Kent,

That's the problem. The invoice was for a front and rear muffler. I was under the car and could see that the rear was new but that the other muffler was not. I wasn't sure where the cat was so I wanted to verify before going back for my money.

I'll have to ask about Steve's questions although they work on Mercedes as part of their "specialty" so I would hope that they know the clearance. Sounds like there could be an issue, what is the clearance suppose to be?

Thanks!
