“Bavauto” Headers Group Buy

[Mfever]

Are these getting shipped out this week? Pretty damn excited!

[Bullet Ride]

Sweet!

Edit: what size clamps do we need to connect the collectors to the midpipes?

They are 2" collectors.

just got my headers today! Thanks for putting this together man! And I'll definitely chip in to help with the money you lost.

I would assume an early e34...

So, about the o2 sensor: I may be wrong, but isn't it too short? I have an 87 325is, could I use a 525i o2 sensor as a replacement?

Yes. That is what bav auto recomended when they sold these headers.

Can you guys confirm the part number for the 525i O2 sensor Bav used? Is it 11 78 1 735 710 ?

Or just let me know what year 525i to look up so I can find it.

I got am email from Tubular last night...

The coaters called this afternoon and said they expected to be working on all of the headers this Wednesday and Thursday. That means shipping should, or could begin Friday and the latest Monday. Everyone should begin to get them next week.

Cheers.

Header install went great. Mating it to the hacked up rear section (Rallycross ground contact) I have was a PIA. Eventually a 2-1 collector, 2.5" single pipe, race muffler and dump before trailing arm will go in. Lost a bit of torque, but the mid-range is great, and it just rips up to 7K.

Any word on the coated headers?

[Bullet Ride]

I know the GB is done, but were the 318 headers for the m10 or m42? Specs on them?

I believe they make a headers for both the M10 and M42. The only info I have is that it's a 4-1 design and the primaries are the same size as the M20 headers.

[tinkerputzer]

Yes. That is what bav auto recomended when they sold these headers.

With regards to how the mid pipes should fit, refer to post #85 I described how things are supposed to go together.

Ahhh I didn't even think about that! Glad you reminded me. I would have figured it out, but thanks for the reminder!

Got mine today!!!!!!! They are awesome, I am a little confused about how the midpipe will fit into my back box. On has the two hole doughnut, but the other doesn't, I guess it just slips into my exhaust pipe?
Whatever, I am sure it won't be a problem. The construction and quality is leagues above any ebay reps out there, and they are worth the extra couple hundred bucks.
Kudos again Steve, you have made me extremely happy, which is not an easy task. I will proudly rock these and tell everyone who made them happen.

I'm glad they turned out nice and I'm glad that they make you happy dude
