Right now my car is wayyyyy to quiet. I have A Dynomaz Cat-back with a gutted third cat. I would like to get true duals but my dad won't let me. If had a y-pipe put in where the third cat was, and had two downtubes put in where the precats are would it be louder? I used to run no mufflers. But I just couldn't take that ricey sound anymore. If a ran no cats and the Dynomax ST's would it sound good? Oh and I would get a chip or MIIL eliminators if I did this Thanks.
