I do not have the money for a full cat-back exhaust system but really would like to get some extra sound. Anyone know how replacing the oem cat's with straight pipes, lets say from fast intentions, and keeping everything else stock would sound? Can't find the specific setup on youtube. I don't want very loud, I want it to be noticeable though. I can't throw a CEL either for emissions purposes. Oh, I do not want a lot of rasp either, some is ok though. Any help is greatly appreciated!
