The collector is actually very smooth. It has been ground down to make sure there is no roughness.

On another thread, 97supratt had a problem with a Megan Racing test pipe so he equates everything associated with this brand as junk. He just like to generalize things. On another thread below, he does the same thing and argues with another member about an HKS replica:

I am a firm believer of you get what you pay for as well. I have been researching headers for a while. I think I am going to go with the Strup, DC Sports, or Alphawerks.

Thats why I asked him to dyno the results! It's not a generalization that most of the top speed/megan racing stuff don't make as much power as the crawfords. It's also not a generalization that most of the top speed/megan racing stuff don't fit as good as crawfords. Am I really generalizing here? Or are you being a smarta$$ internet cadet.

These are my opinions, if you don't like it then stop reading them. I'm not on this forum to be nice to people who buy $100 headers then have to pay 400 for labor to replace them because something went wrong. I have the best headers in the world right now, STOCK! No fitment issues, and zero out of my pocket expense. Do you also have a problem with that?

The facts are, you will spend $200 bucks on headers from ebay, spend another $400 on install, and get 5whp with a leak later on. hahah

ok... exclude crawford o this equaltion

stru, alphawerks, nismo, stillen, topspeed, dc sport, megan.... who makes more gains? id said they are alla bout the same 8 whp all +-1 soo to pay an extra 200-300 for the name is not worth it... now i think thats cause is same design, so its jsut abotu the buidl quality...not necesarly performance wise cuase its same...
All i personally care is which will be better turbo wise...thats why i keep askign for the collector size..and if they are equal length or not

so right now only crawford and xerd are the only equal length

Do you work for Top Speed? Because usually the inside collector isn't ground down like that. Plus your location is "Top Speed", so if it walks like a duck and talks like a duck, it might just be a duck.

The only turbo kit that will fit stock or aftermarket headers is the Turbonetics kit, and the only aftermarket headers you can use with the Turbonetics kit is alphawerks but they haven't shown any gains compared to stock cast iron manifolds.

You need to chill out, first of all. For someone who does not even have after-market headers, you sure do have strong opinions about something you don't even own. I'd trust my judgement based on experience, not from your opinion, that's for sure.

BTW, your name calling is childish & disrespectful? Mods -- how about calling for a ban? Look at other threads where this poster is disrespectful to other members.

I don't need to have headers on my car to have knowledge. So I have nitrous, does that make you any less knowledgable of nitrous? No! These are my opinions, either deal with it or leave. It's a public forum and I have a right to my own opinion, whether you agree or disagree that is totally up to you.

Good day.

supratt,

FYI... the stock headers are small, very small and they're two stamped steel halves welded together. I took them apart during my header installation because I was curious, with everyone stating they are "cast iron". I was surprised, but its a easy way to keep manu. cost down... also uses less material. Whether or not headers in general give huge or marginal gains seems to have been proven to around 5-8whp. Thats good enough for me and it sounds badazz.

IMO, I would rank the headers I'm familar with in the following manner based on overall quality and close to equal length.
1-Nismo (take a very, very close look at the craftsmenship + diff. tube dia.)
2-Crawford
3-Strup/Alpha
4-Megan (because of the tack welded bracing-tabs)
5-Topspeed

I own TopSpeed, I've had them on for over a year and half now, still good
Picked them up for $200 shippped and JETHOT coated for another $200. Installed them myself for fun and a learning experience...
