    What exhaust manifold are you running on your 24v swap?

    Hey guys, I just finished up my m52 swap and my leaky exhaust is driving me crazy and I want to fix it.
    I'm currently running cast iron m50 exhaust manifold but the custom Downpipe that was made has generic triangle flanges and its just not doing the job. I keep leaking from the flanges and my exhaust shop can not get a hold of BMW flanges for some reason. Now, I'm already 300 bucks in the hole for this stupid Downpipe and BMW wants 50 bucks a flange. I don't really want to spend another 200-300 bucks to get my stock manifolds to work, so I have seen that many guys seem to use cheapo eBay headers (what I should have done from te beginning).
    So what are you running on your swap? eBay seems to sell several different types. I want to make sure I order the correct ones.
    Thanks guys.

      M52 Manifolds because they are much easier to modify than the cast OBDI.

            Thanks guys. Ill check out the suggestions above.

            These eBay cheapo headers can hold up? No cracking or "massaging" needed to install?

              How raspy? I don't mind a little lol.

              I'm going to check out YouTube. I'm sure guys have posted their exhaust sounds

                Modded OBDII manifolds, much better quality than the ebay offerings but still budget friendly with OBDI midpipe/cat.

                  We cut off the reducing end and welded on V-bands. The guy who did my exhaust does TIG welding for a living and said he thought they were a good deal.

                  The stock bung locations are useless. We drilled holes and welded in new ones.

                  I'm dual stainless all the way back, and it's a little raspy. Changing intakes from an in-bay cone to a CAI helped. There are a couple videos of mine in Lola's build thread.

                  Dunno. These are the ones which were recommended to me, so they're the ones I recommend to everyone else looking for cheapo eBay headers.

                    These are what I used. Needed a little massaging to clear the subframe and one or two holes where they bolt to the head slightly enlarged, but that's about it. I haven't had any issues with O2 bung location, but do have some rasp. I kinda wish I had them powder coated before installing though, would look a little nicer and I've heard it cuts down a little of the rasp.
