i have a 2000 integra ls and have a 4-2-1 megan racing header that i will be installing within the next week or so. I disconnect the negative (black) battery terminal first, i know that. then what? is it just a simple un-bolt my stock header and bolt on the new header? or do i have to do stuff with the o2 sensors and what not? thanks.

 

Im assuming it would be impossible to pay the money to get someone to do it for you. Im the type of person that doesn't really do things to my car by myself, because I know if I do it, something is bound to break or not work properly

 

be careful not to damage the o2 sensor - it ain't cheap to replace.

 

header install is pretty str8 foward..disconect the negative batt...then jack up the car mayb put some spare tires under ur tire to hold up the car....unscrew all the bolts keep all the gaskets...and just be careful with the 02sensor ..they are not cheap..lol...i changed my own header on my 00 si ..and installed my cai pretty easy beginner stuff...should b pretty easy and fun

 

don't use a scissor jack and spare tires. GET JACK STANDS. they're worth the money.

 

where exactly is the O2 sensor located??? i am in the process of doing this install myself (DC sport Header for 2007 SI). i just want to know where everything is b4 i strart taking stuff apart. i have a skunk2 catback, and now putting on this header will eliminate my cat. is this a good idea? or should i buy one of those high flow spun metal converters as well and attache it to the header and the catback? where should i relocate my O2 sensor once i attach my new header, and what is a good simulator/CEL to go with?.. thanks all in advance, but i figured i;d ask this Q here since me and this guy both need help.

 

or do they make a smaller bolt on cat that would work with my DC sport header and catback exhaust. cuz the high flow cat i was looking at will work with this setup, i just need to cut and weld some pipes together. thanks.
