Thanks, I'd say around 1100 in these motors and things are gonna go south. But I'm just saying, nothing to back that up.

Pics from inside the header flange on j_blocks old ebay headers.

Thanks James



I know bb headers were not just a pipe in a hole like this.

Wonder if someone has any BB headers laying around? They could take a picture? Correct, I never stated the BB headers looked like that picture. I stated they took a dremel/grinder to grind down that edge of the pipe. https://forum.e46fanatics.com/showthread.php?t=867788 Do the research kids!

Sorry for the late responds on the pictures that was requested. They are welded in the inside and grind down per our request.











Also, all sets is lazer etch with SN.

Very good pictures! I didn't know they were all numbered. I stand corrected the headers do appear to be welded from the inside then ground down. This was nothing personal, just good forum discussion! Thanks BB for posting these pictures!

thanks Anthony! Those are exactly like the ones I installed. I also read the thread, about that guy. To me it seemed like you worked with him more than you had to. A+

I appreciate you.

Can't Wait for the new headers.


And xi, just like you said. No hard feelings, let's get all the correct info out there

Can't figure out a better thread to drop this info, so putting it here.

I was trying to collect more data on the differences between ebay supersprint reps, tecnik gen 3, kromer kraft, and bimmerbrakes gen 3 headers. Here's what I found so far:

Primary tube sizes:
My ebay SS reps - 37mm (this includes ceramic coating)
Kromer Kraft (stepped, starts small and gets larger) - 37.5mm
Technic - 38mm
Bimmerbrakes Gen 3 - 42.5mm

Reference on technic and kromer kraft measurements: https://forum.e46fanatics.com/showth...53#post6469553
ebay ss rep measurements are my own
bimmerbrakes gen 3 measurement provided by Michael on facebook's e46 zhp group

There was discussion over what makes more power, ebay headers/ss reps or bimmerbrakes gen 3.

I've done a dyno with both. NOTE: This was with the same car but with a different dynojet dyno on different days with different temps (60 degrees F with ebay headers vs 72 degrees F with bb gen 3 headers), so don't just look at the peak power numbers, they are not a good comparison.

However, the shape of the torque curve should be a valid comparison

Blue line: ebay headers with borla cat-back exhaust
Red line: bimmerbrakes gen 3 with borla cat-back exhaust


Car mods for the record: ESS twin screw stage 2, 79mm pulley, headers (obviously), borla cat-back, bmw performance intake, turner underdrive pulleys

The common assumption is that the ebay headers/ss reps make more high end power, and the bb gen 3 make more mid range torque. But my dyno results don't support that assumption. In fact, it looks to me that the bimmerbrakes gen 3's keep the torque curve slightly higher in the higher RPM's than the ss reps.
