Dont run a gutted cat, just put a test pipe up. JDM exhausts have to meet JASMA certification, youve probably already seen the logo on the muffler. That is to be certified that the dB of the exhaust is below a certain dB level, amongst other things in the way of build quality and safety standards. Alot of people who don't know think it is a name brand. It is similar to CARB for us in a way. In other words, their exhausts have to be quiet, quieter than ours. You'll like it Im sure from what you said you are looking for in sound. Ive had a JDM exhaust and loved the sound.
