Hi,

I bought a invidia axle back for my 3IS and about to install it myself. Here are a few questions I have.

It comes with 2 donut gasket(one for each side), one side of the gasket is bigger, one side is smaller. Which side face the factory exhaust , which side face the invidia side?

What is the torque spec for the bolts?

Also it comes with new nuts and washers, do the go together on the same side of where the original nuts is right now ?

I am new to all this, please help!

Thanks in advance!
