You're on auto, right? I thought you would like some BP
yes. but i'm on straight flow all the way. no difference. in fact, butt dyno say it feels a lot more responsive compare to s-flow which felt restrictive at acceleration and top end. but my car got some minor head mods laa. current setup is cusco style 4-2-1 headers into 2.5" piping and 2.75" inlet FGK legalis r muffler.

Juz a reference only. Will definitely go to shop and test . Hahahahaha
What you want is a tabung type resonator - this will cut down a lot of the drone and noise. Then for rear a straight tabung type muffler. If possible extend the tip to at least a foot or 1.5ft long and it will cut down the drone altogether or at by a lot.

Like what I did for this car :
