1. You are way late to this party.

Just make your own. Its cake. Just time consuming depending on the style.

thats kind of why I made this post was to see. If any lined up nice before I went and fabbed my own completely...

^ There's a couple of vendors on this site, as well as members that have fabbed up exhaust manifolds.

I'm running an Absurdflow design and totally love it. TurboTim is the guy behind Absurdflow. There are quite a few other members using his exhaust manifolds.

mYea mod already cleaned it up once would rather not lose the useful posts now

if you want a dsm manifold just buy a cheap ebay one reweld the fuck out of it. it would be cheper than trying to cut up a stock manifold to make it work. i tend to throw them away myself.

Seeing if the port spacing lines up is free.

Better yet, here it is from my 2G (DSM) mani:

Ports are almost exactly 2" across. Maybe another 32nd or so. Space between ports is approximately 1 and 9/16". Ports are about 1 and 3/16" tall.

So in order to shut this topic up as everyone wants to, someone measure a BP mani and lets us know that its totaly different.

Anyone? Bueller? Fry?

I cant seem to find the dimensions anywhere online.

Just need a general idea of the port spacing and the width and height of the ports.

Google works better from a different computer...or I suck at searching.

Anyway, here is a jpg of the BP flange:

The ports are 1.89, which will work OK with the DSM ports. The BP ports are 1.18, which also works well to the 1 and 3/16 of the DSM ports. Some matching with a die grinder and you are in business there. The diagram seems to indicate a port sapcing of about 3" on-center, where the DSM is right around 2.5" I am not sure I am reading that right though.

I will check bolt holes, but my guess is that it will fit well with some slotted holes and port-matching.

not to bad at all thanks for the help!

that guy needs to space out his dimensions a lil lol
