Errr....I'd stay away from an Axelback. Those tend to be louder than Catbacks since they are generally made poorly. Most axelback makers are just making them cheap to be loud for those who want more noise.You can find any tip, that you like, that fits the OEM diameter. Any mufflers shop should be able to cut and weld the new tips on.
Or you can buy a new axelback.
