Are you installing the remus kit with resonator delete pipes?
I have the remus race axelback without resonator delete pipes and it fits perfectly on my car with secondary cats. If you are using the resonator delete pipe, then try installing axelback only by clamping back the stock resonator + pipes you've cut off.
How its sounds compare to stock one? Worth that money even if you keep resonators and cats ?
