I have a catted SLP X pipe with flows and it sounds good and all but I had a O/R H pipe with the flows and it sounded much better. But Im thinking about just getting the SLP Race pipes and swap the cats out and put them in. How would this sound compared to being catted? I know the X pipe is more raspier then the H but I really dont want to spend all the hassle and keep swapping out the X and H pipes when inspection comes around. Would it be a little louder with the race pipes or wouldnt I notice any difference in sound? Thanks!
