You cannot compare your NISSAn to a honda. 4 banger are loud. engine work harder.. anywho, maximas are luxury, most people do not want our cars too loud. It get annoying. Btw if you want your car louder, get a y pipe.. Greddy SP is street perfmance, not a whistle..

Yeah... you really need to get the y-pipe to get the sound out...

Sound only comes out when the maximum air flow is allowed, which is 2 1/2 inches in diameter. Stock Y-pipe is far more restricting than that...
