Do you guys know what the stock sizing of the inlet/outlet piping of the AMG mufflers are?

I am looking to replace mine with aftermarket mufflers and I want to know what the correct sizing is before I make my purchase.

 

I pretty sure for the 55 it was 2.5 inches and the 63's are 2.75
Someone with a 55 that knows correct me if I am wrong.

 

I think the 55s have 2.75 also

 

2.75"

 

oh ok...thought I had seen someone in a previous thread mentioning 2.5 but makes sense they would be te same...I guess.

 

anyone know the exact size of the mufflers too (length x width x height). I also thought someone had said it was 2.5"....

 

If you can wait until this weekend for an answer, I will be happy to get my factory muffler out of the storage shed and take measurements for you.

 

ok, thanks.
