How much is the diameter of the piping of the Apexi N1 exhaust for ITR?
Also if bought from Europe will the piping be the same as the same model bought from USA or Japan?


'98 Eurospec ITR B18C with AEM CAI and no cat. until now!

 

60mm

 

As sgT mentioned, 60 mm piping. I would think even the N1 offered in Europe would be same pipe diamter. Look into Type One and Kakimoto as well..

 

what size piping is the jdm apex n1
