Hey i got an 01 Eclipse with the 6G72. I have an AEM V2 Intake and a Skunk2 Catback Exhaust. Im lookin at buyin Megan Racing headers for it and im just wondering if its a good investment since ive heard people have problems with them. Also it says the Check Engine light will come on because of the O2 sensor of course. If i shut it off with a DMM will i b ok? Also will the pipe bolt up to the Catback? What sound will it produce will it still b the low tone of my Skunk2 now?
1: Performance gains will be ok, but not as great compared to other headers that are more expensive.
2: The check engine light will come on unless you get o2 sims or use non foulers. You also have to put an egr breather on in order to not get any codes - there are how to's on both.
3: It should bolt right up to the catback.
4: The sound will be raspy and hollow at high RPM's because of eliminating the cats. It will also smell like unburnt fuel. I suggest getting a magnaflow High flow cat. That will emiminate some of the harshness sound headers will produce and get rid of the smell. And if you still dont like the sound, weld on another resonator/muffler after the HFC. If you put a HFC and extra resonator on - you will have to cut part of your exhaust to make it all fit. This is what I did and it makes your car sound just like it did before the headers were installed, but with better power gains!
When I got the HFC and Resonator it was 110 total for me.
