Dual exhaust or Single???
People will tell you that you will lose low end power due to a loss in backpressure, but just as many people will tell you its a myth. Hell, my car feels quicker than ever with dual flowmasters, but I'm willing to admit maybe its just the good sound creating that illusion. Either way, there definitely isn't a loss in power

theoretically, yes... you should lose some on the low end. but realistically, no... you will hardly notice a difference and you should actually gain a bit on the high end. NOW... if you tune your car, you should gain back the torq + more and also add more high end with the added power. duals really make a statement for both sound and looks... and with a good custom tune, you may also see performance benefits.
