I also recall digging around realOEM and in Euro 130i and Euro e90 330i share the manifolds. Try to confirm though, it was a few months back.

It improved greatly. I have been off work for the last 2 weeks and it has been a lot of city driving but it is still better than my hwy/city mix pre-headers. It can get ridiculously good on the highway.
Proper tires Headers 2nd cat gone tune I would imagine would be pretty good mpg. |

Hi All,
I am having this model built with a single piece mandrel bend piece of pipe in the bends. I should have the first sample within a week or so. If it looks good, I can make as many as I like. |

Yes. Currently, I wasn't pleased with some things so I asked for another sample. I will ask for another update and see what it looks like. Will try to post some pics.

soooo....the custom manifold prototype is done. Notice no welds and all bends in the cat delete section. I have been running mine for months without any issues. I don't want to re-install a new set. Anyone want to test these out let me know. It would be best if you are local.

If you were closer or even in the same country I'd consider taking my car to the dyno stock, mmw and your manifolds to test. They look great and there should be decent HP gains from removing the cats for sure.

I will be able to churn these out quite rapidly if this one last test goes right. Like Michael Corleone's papa said. It will be an offer no one can refuse. |

your sig shows second cats deleted. I really wouldn't recommend you to go completely cat less. I can't roll down the windows period. If you idle for 5 minutes with the window down you will feel sick and maybe get a headache. I'd do primaries or secondaries. Not both.
