Header brands and proven dynos

[Tbonem3]

Fabspeeds are great. They make more power than Euro/CSL. Com'on Ian. You know euro and csl guys would upgrade to SS long tube, of which Fabspeed's are the best replica.

Massive torque. I still have cats in sect 1, and NO TUNE, and my steelgrey pulls so hard I can't believe it. That's a full weighted car with heavy stock wheels. Euros never felt that way to me. Even the ssv1s don't feel any better than fabspeeds (though a different car, my silvergrey).

And the sound is very muscular and deep. Euros are a little zingy-er, buzzier, but with a better motorsport sound. A little more of that hollow wail that I actually like more. But fabspeed and other longtubes make a sound more appreciated by people (less raspy, a little smoother)

Does anybody have any information on Fabspeed headers?

They are reasonably priced and available. Any benefit over euros that anybody can give based on old info lost on m3forum?

No benefit over OE Euros, and also a generally shitty company.

You can buy Supersprint headers but you have to buy the catted section 1 with it.

That’s exactly the route I was going to go. Luckily there’s a shop with a dynojet 10 minutes from me. Aiming to dyno the car and tune around mid to late April.

You dyno'ed around 330 or so was it? Are you going to keep the headers?

I too am looking for headers for my 03’ e46 M3. Multiple shops have told me “they’re” (I’m assuming some government department) cracking down so shops are not carrying them and manufacturers are producing less. I’ve been trying to buy Epic or Supersprint V1 stepped headers. Turner said they’re in the process of taking down their Supersprint headers webpage. They won’t be carrying them any longer. EAS doesn’t stock either brands. Supposedly, they’re back ordered till Nov… Anyone know where I can get Epic or Supersprint V1 headers? I’m planning to couple them with Karbonius CSL air ox and HTE tune.

I have AA headers that I just installed 2 months ago or so, matched with status gruppe’s SCZA exhaust and I love the sound. Was pretty close as to what I was looking for sound wise. Didn’t like the rasp at first but it grew on me. Have not done the dyno yet.

Looking forward to dyno results. If possible, please use a dynojet in SAE mode.

American Racing Headers is what I currently have. 6-1 design, with a dedicated section 1 that reaches 3.5” in diameter. Pretty freaking sweet imo. Everyone who has heard my car has told me it either A) doesn’t sound like an S54, or B) sounds super exotic.

I have not had them tuned yet as I’m waiting for my TMS box to arrive, then will be having HTE tune the car. Will post a full write-up about the cars current setup and results on the dyno.

ARH are badass, however the buy-in price is pretty pricey. Luckily I got offered a deal I couldn’t refuse.

I'm curious what your dyno results will show. I know there's been some heavy criticism around here for a 6-1 design for an S54 but I would like to see what the results are.

According to HTE, the 6-1 design have really good compression above 5k. From what my butt dyno tells me, I can definitely feel a pick up in the higher range. Just really waiting to see what all Hassan can do. I’m hoping for 340 with the airbox, headers, and the muffler.

Sounds awesome, can't wait to see that!
