Gardner Exhaust makes factory original systems right down to the exhaust clamps. I would go to their web site and read their product descriptions. Also, they may be able to assist in info regarding DB level. I would also mention that GM had the chambered exhaust system as standard on Z/28's early in the 1969 model year and available as an option through late April. That is substantially louder than a system with a muffler.
