Pacesetter Headers Ready for the 3400

[whitelightnin04MC]

Very true about the 02 only reading the front cylinders. For boosted apps, you'll definitely want to address that issue.

And chris, I'm guessing that the price has to do with the market. So few are modding the 3400's compared to the many that are modding the 3800's.

I wonder if these will leak like the 3800 headers.

Actually I had it reversed. It has the O2 bung in the downpipe for the front bank. http://www.headermania.com/mm5/merch...de=V6HeadersGA
That means the O2 sensor is only reading the exhaust from the front bank of cylinders (2,4,6) and not all 6.

Yes but the S&S o2 bung just reads the back bank IIRC.

Please explain to we idiots

Interesting... Seems like the O2 bung is awfully far away from the heads though.

I really wish they would have made them to compete with the S&S price wise................

why is it that they are so much more than the 3800 headers?
