Overall cabin noise, and the noise through the firewall with the exhaust shoved right next to it. . It's not a complaint ,but I noticed over my 06 si it's much much nosier.I will take a louder ride for the upgrades on the new gens.
Break the engine in how you want to drive it. There's no need to pamper the car,because machining is so precise now ,the chances of any issues are slim to none. I've personally taken two engines from overhaul straight to dyno and ripped it.advice I was always given by the tuner and racers alike...
Saw some nokya 7000k *80* watt bulbs on ebay,amazon,etc.
Headlights are 55w rated,wouldn't running that much higher of a wattage cause shorts,overheating,and possibly fire,or just general damage to harness?
