Well seems like i got my money back from the tctunerz conflict. i almost purchased a megan header at first.... i have second thoughts, now need to decide and compare between the DC and MEGAN only (not Alphawerks)..


i like to have everyones opinion between the 2 especially for the people who has one.... like as far as performance, sound, quality, longevity


what i found out about these 2 is:

- Megans got a built-in cat that reduces airflow=performance
- DC is just a straight pipe meaning higher airflow= more performance
- DC for tC is known for its raspy sound (have no idea how bad is the sound)
- Megans almost have no raspyness
- Megans users had complaints (SL members) about their built in cat broken off and stuck between exhaust
- for some reason Megans cost less than DC
- Megan is Stainless steel, like any other header
- DC is Stainless steel (i think) with ceramic covered over, which reduces the heat for better performance...



and to let you guys know im using stock exhaust.....



also! if anyone feel like selling there DC header or Megan Headers, PM me! i dont mind buying it from you!

why not alphawerks?

not affordable at this moment....

i would go with DC, because there have been multiple reports on the megan header where the precat FALLS OUT into the exhaust system. total bull if you ask me. if you have the money, get the alpha werks, but if not, get DC.

The DC sounds great when I used the stock exhaust. I had them since December when they first came out and mine are starting to rust :tap:

If you're saying that the statement of the Megan headers breaking apart and depositing debris into the exhaust is "bull", then you are completely incorrect. I am dealing with this myself and I am waiting for Megan's promised free replacement in June.

If you're saying that the fact that those who bought the Megan headers having to deal with such a ridiculous problem is "bull", then I couldn't agree more. The Megan headers were sloppily engineered, with cheap parts, drafty design, and with the intention to lead the header market without any regard for quality. They weren't even shipped with a manual for christ's sake, just the lifetime warranty (thank GOD), and a Megan Racing decal. I can't help but chuckle to myself when I look at that lame decal. I would NEVER put that thing on my car.

So to Dilluvium I can only offer one remaining choice: DC Sports. But here's the thing, the DCs rust, throw a CEL just like the others, and are just as raspy as the Megan and Alphawerks headers (where did you get the idea that Megans were quiet?). I would recommend keeping up with the recent prattle and scrutiny between the different manufacturers. The only way to truly get rid of the noise is to stick to the stock axle-back exhaust, acquire a custom exhaust (or maybe an HKS axle-back which I've read helps out a bit), or hopefully with a redesigned s-pipe from Draxas or CreativeCompacts. James from CC rocks by the way.

I would have suggested the Alphawerks headers and their O2 "smart sim", but since money is an issue, that rules that out doesn't it? Why waste $150-200 on bad engineering, or $400+ for something just as bad as the others minus a few minor perks? Save your money, wait it out, better answers are on the way.

Rust? Where At ?

my dc hasent rusted. go to www.clubsciontc.com reg. and go to videos, i posted my weapon r/dc header/injen exhaust under a video clip. heres a link

I dont have a TC, but i have DC sports on my box and i would strongly recommend buying the DC sports one. No problems with rust, install or anything. It is coated and reduces rust by far. I've heard the part on a TC but they also had the greddy evo 2 cat and it didn't sound too bad to be honest.

i heard DC header do not come with a new manifold gasket... isnt that recommended for every after market header??? to prevent leaks and problems... anyone installed there DC's with no new gasket?

Well, I have had the Megan running for 3000+ miles and no precat failure, sounds great and looks great. No complaints here

i heard DC header do not come with a new manifold gasket... isnt that recommended for every after market header??? to prevent leaks and problems... anyone installed there DC's with no new gasket?

None of the manufacturers supply a new one (some of them don't even come with an installation manual!), and many installers have said to just go ahead and re-use the gasket from the old manifold. I think that's what a lot of us did. When I took it off I didn't see any reason why it couldn't just pop right on the new headers and seat in the s-pipe just fine. It wasn't heavily damaged or warped or anything like that.

can u put the stock heat shield that sits on the oem header over the megan or the dc?

can u put the stock heat shield that sits on the oem header over the megan or the dc?

No. It won't fit over the new flanges. The stock header is much narrower where the heatshield should go because the first catalytic converter is right there. If you buy an aftermarket header you will lose your first cat .

well i think it is recommended to get a new manifold gasket... all megan header and i think alpha comes with one...

with a new gasket, when it is heated it expands so it forms a better seal to the new headers... the OEM gasket is already expanded to the OEM header, a new gasket is a good choice...


anyone had any sort of leaks when they installed the DC's???

Does this void my warranty with Scion and the extended warranty?

And if I remove the first cat and put the DC header on, won't i fail California's ungodly anal emissions test? (moving there at the end of the year)

if the answer is no to both, goody, im buying mine soon ^^

yes & yes just dont rev hard around the cops and turn your car off when you get pulled over..

I would just get a DC i have one on my other car for a couple of years now and i see no rust but it did turn to a bronze look now since it was stainless steal. plus DC are smog legal so i would just get those.

They're smog legal? That's news to me! :silly:

1> No, it will not void your warranty unless Scion can prove that it's what caused a failure.

2> The extended warranty does not go into effect until your factory warranty expires, so no, it will not void the extended warranty.

3> Yeah, you'll fail. Both emissions and visual.

It's best to keep your stock header around when you need to get smogged, which shouldn't be for a long time.

I bought the megan header, the precat broke off about 1,000 miles after installing it, after that it got stuck in the exhaust midpipe.

wait until june when megan comes out with a new design.

screw emissions in CA. dont forget no SMOG on scions for 6 years due to that new law about new cars. Do a search under "abatement fee" and you should find it. So with no SMOG for 6 years have fun. then switch back for SMOG every 2 years like i plan.....DC all the way!

i have a hp racing concept header. runs great a little raspy and throws a cell. but hopefully my buddies here in sl are right about the little anti fouler fix. we will see tonight when i put it on.

i would get the dc header. i have never heard of megan untill i started going on sl. dc has been around for years and are known for high quality products.

DC Sports has the biggest history and experiecne. don't forget, DC Sports is with AEM and you know how big AEM is. that alone tells you that you should get DC Sports

That's the most uneducated response I think I've ever heard on here. You get a cookie :clap:

?? its true though. alphawerks and megan racing isn't as big as DC SPorts is.

So because they're bigger, you should automatically choose them? Sounds more like following the heard than anything else.

Apc is the biggest. Can't wait for them to release their patented vinyl, spinning led headers.....

APC is just plain stupid. they may be big but they're big on the crappy side. the stuff that goes on in KMarts and etc. do you see DC sports in KMart?

i agree.... APC is a part of the walmart and kmart products..... just like that weird name hotdog brand that walmart sell for 99 cents (compared to FRANKs hotdog 2 dollar something).... cheap quality... also computers like cheap all around Heward Packerd only walmart would sell...



but anyway!!i just got my DC header yesterday and got it installed 6 hours ago.... when guys try to take off the O2 sensor, make sure you put plenty of w-40, like atleast every 10min. intill it twists off.. it was a pain in the ___, i had to use an adjustable wrench (cant find the sized wrench) and tap it with a hammer intill it actually moves..


also added the anti fouler. CEL is off but i dont for how long... i drove it atleast 30 miles already and no CEL... but still i wont consider it fixed cause it could come up possibly...

also if you guys notice, when you buy an anti-fouler theres 2 types (42002 and 42009), one is actually longer than the other... i got the longer piece... im not sure if it makes any difference, but just letting you guys know that....

as for performance, it is impressive.... when drove a bit longer i redline up to 1st and 2nd. i notice the speedometer was rushing from 25 to 45 quick! as for sound there is none... what the hell was everyone talkin about??? the people with headers and stock exhaust... i hear mostly my damper...


i really like this header.. performance is great.. very noticable... only problem about DC ceramic header is rust which i have not seen yet, but its possible....

DC sports will not fail you. this company has a HUGE R&D program. iono if alphawekrs or megan racing has one as big as DC Sports.

im sure alphawerks headers are better than DC...... really, any headers thats over 500 dollars is top quality... 800 dollar exhaust, top quality

So just for clarification. Any header out there right now with the TRD exhaust will sound bad?

a higher price doesn't mean its a better product. they might charge more cuz they're not as endorsed as DC Sports might be.

i won't know for sure until i have both to test...which i won't xP

drove it for over 60 miles today... no CEL... sweet

cool. how does it sound?

my intake just grows abit more... no sound coming from the exhaust tho....

might have to get the dc headers now, cheaper than the alphas

Bump for a sound clip plz :lalala:
