Hey all, new here and haven't made my proper intro on the forums but had this done today and wanted to share. I replaced the factory catalytics with GTM resonated test pipes (GTM-HR000-R) using Z1 metal HR/HVR gaskets. The Nissan has a bit of a growl to it now and is much happier in the 45-6600 rpm range. Not planning on doing much else aside from a tune until the warranty runs out but thought these looked pretty tucked up under there. Enjoy!
ps- Sorry if I am posting any of this incorrectly- first post!
