Whats the differences between the Perrin and the Maddad EL headers? As far as piping size anyway.

I see 25 lbs of torque increase at 5250 rpm, not 30-40.

Everybody's setup is different. Parts work together as a whole not always as a bunch of cumulative parts so results may vary.

As far as the ongoing Honda comment goes, I got another video today - a laptop video, sound isn't great, but generally represents how deep (and non-'Honda') it is.

Here:

In person, it sounds the most like a turbo 240. Really close to an SR20 kind of sound. I have two other videos on youtube that sound better than this too.

My EL makes my car sound fantastic. It has a more refined exotic sound which surprises people when they see the bread box making the music.

Exactly. People don't get the exotic appeal. Definitely not like any Subaru I've heard.

I LOVE the sound of my car. Then when the EWG opens and dumps to atmosphere it's lovely.

I'm assuming that the headers that crack are around the mounting flanges? Would headers with a flex pipe be the way to go to prevent cracking?

It helps. Mine for reference have 2 flex joints.

http://www.grdstore.com/fujitsubo-wr...der-p-504.html

Considering how much metal expands and contracts under thermal load, it amazes me there are even headers out there with no flex section. Add the fact the engine moves and vibrates to further weaken at stress points.

Also many headers are made with too thin a metal. My Maddad's were pretty thick and heavy. VERY few cracked Maddad headers if any at all.

My Tomei header has slip joints, and, perhaps because it's also been wrapped its whole life, it's lasted 13K miles and a Chicago winter with no issues so far. Slip/flex joints greatly reduce chances of cracking.

so are the Maddad and Tomei pretty much the exact same thing. They both seem to be the highest quality EL headers out right now unless one goes and spends several thousand on the Full Race ones.

MadDad and Tomei are made by same manufacturer but the Maddad's have a different sized velocity stack and thicker material, and bigger ports from what Rich told me.

No doubt. Most people give honda's no love, especially civics. Most Americans seem to have no appreciation for revs, torque supersedes all. The jdm vs. usdm sti is a good example of this difference. The jdm version has a rev happy motor with a very large power band, while the usdm motor has a smaller power band with more low end torque.

great videos. I did not know those little 2.0 can spool that quick. That makes me want a twin scroll. Imagine that on a 2.5! NO LAG

But not as efficient. It'll make crazy tq crazy fast but it'll die off pretty hard after 5K rpms on any turbo that is small enough to spool like that.

Very true. That's why I'm not a huge fan of minimizing lag as much as possible...it's always a compromise.
