02 levin extractors and air intake help needed

[Mealsy]

hey guys

just need some help on what i should do about my exhaust on my 02 levin.

im looking at getting extractors put on through a high flow cat and sporty muffler. im looking to get some better performance gains through the bottom and middle of the drive.

i have a couple of quotes but im not too sure if im going for the right thing here. as stated im looking for gains down the bottom and middle range but not alot of drone. something that sounds good if i give the throttle a bit.

please help me out and any criticism is appreciated.

also im contemplating re routing the air intake from behind the head light to behind the front bumper with some flexi hose running from a collector behind the bumper and into the air box and replacing the stock filter with a k&n.

any ideas with this will also be appreciated.

thanks for your help guys and your time

For headers you have a choice of PPE:

or

Wildcat:

Either headers will give you more bottom end and mid range power. They are not bolt on solutions and will need the rest of the exhaust system modded to suit as they are longer then the original header they replace.
