| This was on 300zxclub recently from John at Z1.... "I'm sorry but if you want that rumble you want B&B. It will cost you power but it give you the throaty sound. I would reccomend getting something else for performance. We've removed B&B mufflers and discovered an extra 30rwhp on a car with back to back testing." The post can be found here....
