Hi All, I will be attempting to install the Milltek TBE tomorrow (ceramic coated the dump pipe, home job, and looks awesome!!). My kit did not come with a Turbo outlet gasket. Can I reuse the stock one? if not, are they readily available at exhaust shops? Also is there a particular torque value for the bolts on the turbo end or just tighten? Thanks. Fingers crossed I wont get a CEL.
