Question about rasp

ok so, on my M3 i've made some mods that greatly increased the rasp. I have SGT headers, stock section 1, rouge x pipe with evc and a custom muffler. I do like a little bit of rasp but what should I get for section one to reduce some of it? I know the AR-20s and AR-25s reduce it too much IMO so what are my options? I know SGT has a pretty cool rasp pipe but how is the Custom Performance Rasp Terminator w/Cross-Over (RTX)????? What does the cross over do also? are rasp pipes and resonators the same thing? rasp terminators take it one step further than the rasp pipes correct??
