thats because you buy crap parts! and dont tighten all the bolts up, DD a car with header/exhaust is perfect way to gain mph and few hp and make it sound amazing all at same time. theres no reason not to upgrade!I wouldn't put a header on a daily, I had a generic 4-2-1 and it was pretty rattly, even with stock exhaust.
now as far as HID help, 4300K is best kelvins for best light output. HID arnt expensive, when you look at big picture of lighting, retrofitting is expensive! talking around $500+ but most cant afford that nor will pay that much or just dont understand why why its's needed. so look into DDM tuning brand, they sell around $40 to $50 cant remember but come with lifetime warranty. 35watts are mainly used for fogs only.
