Headers Thread

headers are a big deal on any e46, so i figured there must be a dedicated header thread out there, can someone show me where to find it? if not, i have some questions that i have not been able to research save for the poor quality of ebay headers.

these three headers all claim quality, performance and fitment,
-AA
-Supersprint
-Bimmerbrakes
-Stett

yet the AA and Supersprint cost thousands, while the las two cost hundreds. why is that? should i be weary of spending less? (or, getting what i paid for?)

Any feedback will help. thank you

They'll all be within 5whp of each other, and I've never heard of any of them "failing."

The AA's are the biggest rippoff, and the SS are the original that all the others copy. If you can afford it, get them, but the Bimmerbrakes and Stett headers should work just as well.

If you can wait until April. We will be releasing out Equal Length Headers for the 325/330

Say what?! Details, and plans for an m52 version?

Don't you guys already sell those headers??

I am awaiting delivery of my new M3 headers. They are from ebay seller "relentless_performance" In the ad,the seller says that their headers do not have any fitment issues with oem studs,fcab,or engine mounts. That's a bold statement. They look really good and I will be doing a thread about how they go. I have previously installed some 100$ ebay headers on a 330 so this isn't my first attempt at this. The M3 versions are going for 280 plus shipping and the seller has me confident that these will be quality parts.

Yeeee buddy. You'll be getting an order in April

What about loss of torque? The back pressure will change, and would these equal length headers be more suited to top end gains and heat expulsion rather then low-mid range grunt

I've never seen any headers on these cars lose low end torque. You are correct, there will probably proper scavenging leading to a potential increase in low to mid rpm power. I don't expect there to be a much of a difference in peak power.

Eh? I was under the impression the headers you sold are 100% fit?

Equal Length? Whats the difference?

They are 100% fit

Gen 3 headers-equal length


Bimmerbrake headers - not equal length




see the difference?

What type of performance increase would I see for those?
