Hey gents,

Can you confirm what the stock diameter of our exhaust piping is?

Am thinking about losing resonator and/or 2nd cats and want to make sure I buy the correct size SS piping.

I believe it's 2.75" but may be wrong...

If that is correct, should I weld in piping that is a bit larger than that or the same size?

Any help is much appreciated.

Thanks,

Chris

It is, but before/after cats & resonators it does crimp down to as narrow as 2.5"OD on many 6.3 AMG models.

The pipe is 2.5" and you should use the same SS pipe size.
