What Z are you asking about???? Tomorrow is Sunday - is that shop open on Sunday?

Today is Sunday but the shop may be closed tomorrow as it's a federal holiday.

OMG - I've lost a DAY!!.... and I must have missed Church also...

As I recall - the OEM pipe size on the 240Z was closer to 1 5/8 inch.. like 40 or 41mm. In the US the closest standard exhaust pipe size would be 1 3/4 inch.

But then he may have been asking about his 280Z...

2 and a half is what all say is the best for a nice exhaust.I run 3 inch and feel i am losing some bottom end power.Car still seems fast but some local z thugs told me i am leaving power on the table with my set up.It was a turbo car before but running su setup now.James Salvato Santa Fe New Mexico usa....
