I sold my flowmasters and i'm definetly getting some hookers, but i'm debating which ones i want now. I was going with the aerochambers and then started reading some post on here how some ppl got them and they were straight through and others weren't. Well in summit, they have "aerochamber" and "maximum flow" mufflers listed together. It says the maximum flow are straight through and the aerochambers have chambers (duh). Well anyhow, i'm wanting the best flowing muffler i can get w/o it actually being a straight pipe so i'm gonna get the aerochamber, so i'm needing to know how everybody is liking the TRUE aerochamber mufflers, not the straight through "maximum flow" muffler.
