So this adapter is needed in order to connect any aftermarket front to the PRL N1 exhaust. This needed do to how the N1 is designed to be more universal and fit 1.5 and 2.0. Came with all need hardware and gaskets. I know it price seems high, but your getting their hardware and gasket kit basically free. So does work? Yes and no. It is designed to work with the PRL front pipe. That's the only one they used for design and testing. Other front pipes on the other hand do not. You will need to modify this to match that brands front pipe or the other way around. That was my issue running a RV6 front pipe. Not a seller issue just a over site by PRL.
