I recently installed a upr o/r x and a bbk cai got it at a deal. I'm not sure I'm going to leave the o/r x on. I have a slp catback and with this setup it is really raspy and loud. It is so loud that I have to short shift to keep from getting unwanted attention, I have been even asked if I had mufflers on the car. I was wondering if I went to a o/r h would it quiet it down and not be as raspy, or should I go with a catted mid pipe whether it is a x or h. I thought about changing the catback to quiet it down. I'm new at this and any help would be appreciated.
