When installing the CAE shifter, the transmission must be lowered from the tunnel to give you room to work and remove the selector rod, shifter bracket and other components. To get there the section 1, section 2, and heat shield must be removed.
While you're removing all these components, you'll be able to find any exhaust leaks that are present, like we did. Replace all your old gaskets and no more problems! Bmw recommends replacing the header to section 1 ring every time you take the exhaust apart, up to you though!
Section 2(midpipe) to rear muffler- this ring seals the mid pipe to the rear mufflers- we’ve provided a choice between bow and HJS.
There is plenty of hardware you may need to replace, including the exhaust flanges from midpipe to muffler, or nuts and bolts to connect your exhaust!
