I need opinions. i have a 2003 honda accord lx 2.4, i right now have installed DC Headers and DC cat backs. i want to know would it be worth it/better to remove the cat and run a pipe therefore deleting my front o2 sensor, or installing a high flow Cat. Would installing a high flow cat make it sequentially louder over having stock cat? i do want it to be a little bit louder than it is now but not by much as if i was making a full straight pipe.
