I’m ordering some super sprint secondary cat delete pipes today and was also thinking about getting the X pipe as well. then I thought of 2 alternatives. I’m guessing that the resonator is full of fiberglass material? If so, I wonder what the sound would be like if it was all removed? Another option seems that a decent exhaust shop could just cut the resonator out and weld in straight pipe. The Larini H pipes seem to keep the exhaust separated so I suppose this would be similar?
