Yes,approximately 5DB difference at idle and at 6000RPM....between a stock muffler and a slip on with no dB killer installed

Has anyone done a decat? I would think the stock header would not work well with such a large opening after removing the cat. If someone did do a decat I doubt they would be running the stock can, so way too many variables.

What is it you are looking for. Of course it would be louder.

Wondered if anyone had actually just butchered the innerds from the cat (popular route with the ZX14).
