...or cat pipes laying around? Please do me a favor and measure the rear port bolt distance and center hole. I'm interested of conection between catalysator pipe and headers, not the ports that mate cylinder heads. Bolt distance is the most important. Center hole I believe is for 2,5" pipe.

I'm going to do pipes and don't want to hack original cat pipes. Of course I could unbolt cat pipes out of my own car but thats time consuming and would like to have all set up before.

I have tryed to contact several Ebay sellers without any luck.

Thanks

I have E55 and CLK55 headers somewhere. So you want to measure the distance between the center of the bolt holes and the diameter of the pipe itself? The CLK and E headers look different but maybe thos emeasurements are the same. I can try to check this weekend for you

I have a stock passenger E out but don't understand what you are looking for either....

not sure what you need. ive oem e55 headers for sale tho.

I have a set of factory E63 manifolds.

Wow thanks guys to help me. Well... I try to explain again. Heres the scetchy drawning I made in hurry. It's suppose to be rear port of the exhaust manifold. What is the distance between bolt holes?

And with rear port I mean the conection that faces down. Not those cylinder head flanges.

center bolt to center bolt appears to be about 80mm that is the best angle i could get but it is right at 80

Yes! Thank you sir. This is just what I was looking for. And let me clear one more thing... This is E55 manifold? Not 500?

Btw... Does all bolts opened easy? Anyone ever snapped those bolts? Lower flange bolts are quite long 50-60mm by eyeballing and thread is only M8.

While y'all have your manifolds out, Would someone measure the stud spacing on the exhaust port side (spacing between two studs of adjacent ports, assuming they're all the same).

I'd like to mount my slip fit headers on a board, and do a test fit of the collector.

Thanks.

sorry about these being so large but if this is what you are looking for it came to 4.25" i'm not so sure why the angle is so tough to get..

uraberg

Thanks. That's exactly what I need.
