This gasket kit increases the surface area of the flange to ensure a better mating surface between your stock components and your ETS parts and includes the following:
2.50" Graphite 2-Bolt Adapter Gasket (Stock Flange)
ETS Adapter Plate - Middle Sandwich Plate
3.00" Vibrant Metallic 2-Bolt Gasket (ETS Flange)
QUESTIONS & ANSWERS
Ask a Question-
I have a borla cat back (2.75) at the flange and I want to put a test pipe (3in) and heard something about using this part to make sure there won’t be a exhaust leak. Will this work?
Yup! You will most likely need an adapter flange found at the link below. This flange allows you to run a factory 2.75" gasket and a 3.0" gasket. 3" Test Pipe -> 3.0" Gasket -> Adapter Flange -> 2.75" Gasket -> 2.75" Exhaust System.

Do you need to use a gasket on either side of the flange?
Yes, both sides need a gasket. 1 side uses the stock gasket the other side uses a 3" gasket.
-
Does this adapter flange have to be welded to the stock CAT in order to run the ETS 3 inch catback? Or does the flange just go inbetween the two pipes with gaskets on each side?
The flange is just used between the 2 parts to add sealing surface area. No welding is required.
