Re: headers and exhaust
If you really want to get headers your choices are limited, but I'd go MAC LT, MAC high flow catted H-pipe, and then you have your choice of cat back systems from their. Headers really aren't gonna give you a lot of power if your car currently consists of just bolt ons. Maybe worth a few, but not significant enough to pour out the money and time in my opinion. I'd just get a nice high flow H-pipe and good cat back system. I'm a flowmaster fan and have had my exhaust for 50K miles now and still sounds great. 40 series flowmasters = nice.
