3SX Non-Turbo 2.5" Test Fit Race Pipe
3SX offers a straight-through race pipe that directly replaces the factory catalytic converter. This is the ultimate in eliminating exhaust restrictions. :-) This pipe will work with the 3SX NA Downpipe or the factory downpipe. Likewise, it will bolt directly up to any aftermarket cat-back exhaust system designed to mate up to a stock system. The catch-22, however, is that they are NOT emission legal so your car will not pass emissions inspections with this pipe installed.
NOTE: This is for the pipe only, gaskets are sold separately. If you are mating this with a stock downpipe, you need the 002 gasket. If you are mating this with an aftermarket downpipe, you will need the 004 gasket (larger diameter).
** NOT STREET LEGAL, FOR TEST FIT ONLY **
NOTE: These pipes are right at 17 inches long (~43cm). It has been brought to our attention that some GTO models (Non-USA) may have a main catalytic converter that is a shorter length and have a sensor just after the main cat. If you are outside the USA, please measure your cat length to confirm fitment.
NOTE2: Due to the age of the cars at this point, we recommend using new mounting bolts/washers/nuts rather than the stock studs, which will likely have to be cut off during removal anyway. Mounting hardware is not included with the race pipe, it can be found at your local hardware store.
