I just ordered a Stillen dual rear exit. I looked around quite a bit. I like the look of a rear exit. Everybody had a different opinion on what is best, that just makes sense, everybody has different likes. I wanted a rear dual exit with no power loss, no droan issues, and quiet unitl you punch it. I had been looking at a single side exit magnaflow but backorder issues and my desire for a dual rear exit tossed that one out. I am hoping I made the right choice, I'll let you know after I put it on.
