That's close to what I'm running, I have Kooks LT with an O/R H instead of an X and FR500 mufflers. I had the FR500 mufflers on the car before the headers and cat delete and they seemed fine, nice sound improvement from stock. The LT and O/R H completely changed everything, it is so fucking loud now almost everyone asks how I don't get arrested. I had it idling in the driveway the other day and a neighbor five houses down texted me and asked if I had a drag car running at the house. The cams were a big contributor to that, but it is loud.
