05 E85 Z4 stock exhaust diameter

[JimLaheyJunior]

Can’t find any info on the actual diameter pipe I need for deleting the rear x pipe style resonator. Does anybody have any metal suggestions for sound as well? I was thinking stainless steel.

Did the mid resonator delete on my E86 and the exhaust was 2 inch OD. Stainless is probably your best bet unless you can afford Titanium
