Brought the exhaust system to a mechanic and bought a 2.5 inch aero turbine 14 inch resonator. He installed the system for me and did minor cutting with flared flanges to suit a more custom fit. The exhaust system itself lacked a resonator to bolt up to the Rabbit, hence it was for a GTI. Resonator installed including and adapter lengthened extension for 2.25 inch to 2.5 inch and Mach fitted/welded into place. Very satisfied with product and final exhaust note. Posted it all over facebook with pictures.
