Problem with FI exhaust and Z1 diff cover

lj909 · 09-17-2017, 12:44 AM

I have a nismo oem exhaust and that fin was so close it was making a contact sound. I don't know why they made it like this. Even in there promotional video you can see it's almost touching.

a small 5" grinder with a thin cut off wheel will make short work of it.

Remove the Z1 differential cover and use a grinder and grind down the fins as even as possible. You should be able to make it clear your FI exhaust with some work. You will just have to refill your differential fluid.
