No worries. My x-pipe actually is catless. While it didn't produce a ton of HP up top, it produced a significant amount of torque in the mid-range which is what the car was lacking. Adding high octane takes care of the power at the top end. So the combo of the SC, catless x-pipe and higher octane is fantastic in daily driving and track conditions.
Good luck with your build.
