In typical Nissan fashion, the Maxima's engine is buttery-smooth at idle and pulls hard throughout the rpm band. The extra power comes from new intake and exhaust manifolds, Nissan's Variable Induction System and a new muffler that incorporates a valve that opens at 2,000 rpm to reduce exhaust back pressure.
interesting how they didn't just leave the thing open all the time... jesus christ, some of you need to get that idiot ricer mentality out of your head and do some damned research before spewing misinformation.
