“Bavauto” Headers Group Buy

[Gary Horneck]

Sent $35 to cover the added expenses on this deal. Got to test the headers on Sunday at Tri-Lakes Sports Car Club Autocross. Nice mid-range boost.

Thanks Gary, appreciate it.

How'd they sound ;)

[Gary Horneck]

Has a sound that I remember from watching WTCC 635's. It's a unique raspy sound that I could pick out of a group of cars sight unseen.

Did we decide on those O2 sensors coming from the e34?

I e-mailed Bavauto and this was the response:

Jerry, thank you for your inquiry, we used part number 13 037 for the
headers, same sensor just a longer wire. -Andy

That's the bavauto part number. There is no other number on their site so I'm not sure how to cross reference it.

Do you have solid mounts? Seems like a lot of transmission hum. Might just be the video.

13037 is actually the Bosch part number for the old style (push) connector, the new style (screw on) Bosch part number is 13052.
But if your O2 sensor is working well, you can always cut the connector and extend the pig tail.

[Gary Horneck]

Yes, solid mounts everywhere...

That explains it. Sounds sweet though.

Be sure to shake the pipes real good before installing, found some tiny ceramic balls dinging around inside mine. Reckon that would cause some annoying rattle if not.

Installed mine today. Went in like a dream, I extended the pigtail on my existing o2 sensor, and it came out fine. I must say, with my exhaust, it is extremely nasty over 5k, deep and raspy, doesn't sound cheap or rice at all. You can control the level of obscenity by staying in the low rpm range easily though. But when it's time to get down.... it gets down. It even pops nicely on the down shift, or sometimes just letting off of the gas.
Love it, can't wait to hook it up to my stroker when it is finally done.

Hmmm, I asked about the connector in a follow up e-mail and he said it would fit. I guess it's a good thing I haven't ordered on yet as it looks like the 052 is cheaper.
