| and any performance differences in the single tip versus the dual tip. "The difference in the Dual tip vs. single tips is about the same as adding a set of resonators." The system is designed for max power and then you can add resonators to tame the sound. The power difference between the set ups is nothing you would feel. It just all adds up for the folks looking for max power in racing situations. For a street car, I would compromise to meet your goals for sound and looks." Short answer is pick your exhaust on the sound level and look you want unless you have a dedicated racing car and are looking for every last drop of hp. H pipe with resonators will be quieter than the X pipe with resonators.
