hi,
iam thinking about getting headers fitted, and i will need a new cat. too,
is there any advantage of getting a high flow cat, this for my 03 accent 1.6L DOHC.

Yeah, it will give you more power... Less flow restriction... Better gas mileage.... just like putting bigger pipes on your ride... its allows more air to travel throught he exhaust. GO for it... won't hurt :D
