For bout a year or so i have had the same exhaust set up and i have been wanting to get it louder, but have been told i cant get it any louder without throwin codes. I have seen in some other threads bout sumthin called ghost sensors, where u can take ur cats off and it not screw with the computer or anything. If there is such a thing how much are they and where can i get them? and if i was able to take the cats off and put a muffler on, would it hurt torque because of backpressure and would it make that much of a sound difference?

any help would be appreciated, thanx!!
