im thinkin bout buying meagen racing headers and i was wanderin if anyone knew from experience how good they are and also do i need to reset the ecu when i put them on cuz i heard that i will need to and that i should of done that when i put my exhaust on too anyone can help me i would appreciate it

wanted to get it . . . but enddin up buy mmw header. . .

I have megan racing headers. i guess with the right setup it's a decent performance gain? i have a custom made dual exhaust, welded on to the catback, and all i can say is that it's loud... stupid loud. my friends tell me it's cause of the headers, but who knows. but after driving a stock tc, my modded tc does feel faster. i have beaten a stock tc, not by a lot though so it's up to you.
even if you reset the ecu, your CEL comes on no matter what, but there is a way to fix it. it's a thread here on the forums, for 25 dollars.

$25???? do a search for the DC header install... it will show you how to make an anti-fouler... put that in your S-pipe o2 sensor... it will cost you $5, and no CEL.... for at least 1200 miles...

I'm very happry with mine, I've had it for over 50K miles now, I'm getting ready to have it jet-hotted so that when I install the TRD supercharger I will avoid all that heat hit the shatf that sits across it, I'm also having half the heat shield(the one that comes with the supercharger) jet-hotted for added protection, just have to make 2 home made brackets to make it work, anyways.....once again I'm happy with my megan header, I also have a custom 2.5" header back exhaust system with a magnaflow exhaust, one cat and one 40" resonator, its sounds great......not raspy at all, almost sounds like a v6.

ok so is there a way to keep the check engine light off??? i really cant have it on i wouldnt care but when u have to get a state inspection in texas the check engine light cant be on or it will fail so i just need a permanent fix for the light or else i cant get the headers kinda sux cuz i really want the headers but not sure if ill get them now?? if there s a fix ill get but i havent found one yet or a permanent fix for now so im gonna hold off on them

Oh yeah....I forgot to mention, I have the anti-fouler and no check engine light for me, I bought it from www.racingsolution.com and It has worked for me for over a year.

they discontinued it is there somewhere else i can get it and it was 1000$??? wtf

No...thats something else, the anti-fouler cost me like $22 dollars, email Bryan at Racing Solution and ask him if he can still get you one.

lol calm down. Go to your local Advanced Auto parts store and ask for some 18MM spark plug anti foulers. For the Megan header you will need three..with one it wont work at all...with two it will only work for a little while...three keeps it off for good. They come two to a pack, so you will need two packs...they are like $4 a pack...

All you have to do is once you get em, drill them out with a half inch drill bit. Just be sure to not mess up the threads. Screw all three anti foulers onto each other. Unscrew the sensor form your s pipe (may want to spray some wd-40 on it and let it set for a few minutes before trying to get it off, it can be tight.). Then, screw your tower of anti foulers onto the s pipe. Lastly, tighten the sensor back on top of the anti foulers, and HoLy Sh*t, no CEL.

ok so put it in the s-pipe not the header itself??? the one in the header wont throw a cel then right?

no, the one on the header measure air/fuel ratio..don't fu*k with that one..the one you put the anti foulers on is the one on the s pipe.

so if i leave the stock s pipe on will it work with it?

yes, the s pipe isn't the prob, the sensor on the s pipe is what gives the CEL.
