WTB S13 5Zigen Border III catback exhaust

Missed out on this one when they were in production. Looking to see if anyone will part with theirs? I remember there were 2 different sizes of pipes, one 60mm and the other 70mm. Mainly interested in the 60mm due to na KA. Thanks

you should get 70mm.

the extra 0.4L displacement on the KA would benefit from the larger piping. Assuming the muffler packing is still okay, there would be no difference in sound... but it's an old exhaust, the packing is probably all gone.

Good luck finding one. Best exhaust I have ever owned
