Well the exhaust turned up today, only thing is i have to wait until Tuesday to get the car it into the garage, If it was a couple of months ago i would've been out under the car now,
The tailpipes are 3.5" external dia, and the exhaust itself is 3" ex dia,

Old single tip exhaust,


Package arrived,


Unwrapped,


In its full glory,


Nice and empty
