    I've just ordered eBay headers (these: For BMW E46 E39 Z4 2.5L 2.8L 3.0L L6 01-06 Performance Exhaust Manifold Headers | eBay), and I assume that most eBay headers are exactly the same, and from what I can tell I won't be able to fit the O2 sensors without relocating the mount on the header...

    Hey guys and gals, Wondering what everyones opinion is on removing the rear cat on my car. From what I've been told from my exhaust shop is that there is a cat at the headers and another cat further down and then the 2 resonators along with the muffler. I would be keeping the headers cat but...

    Hi All, In an attempt to clean my M3's exhaust setup and pass SMOG . I went ahead and purchased Euro Headers + Euro Cats. Now since Euro headers are the raspiest, I am looking for a Supersprint resonated x-pipe (Section 2) to mate with my Supersprint Sport muffler. Preferably in the California...

    I put in new headers and im deleting the post cat 02's. The pre cat o2 sensor for the front header doesnt fit into the front bung. Can I put the sensor in the rear bung instead since it shouldnt matter where they go because I don't have cats. The sensor for the rear header fits fine into the...

    Hi all, I have spent a while searching around for headers for my 2001 330i, but everything I come across seems to be LHD only. Apparently this is due to the steering column. How much work is it to get LHD ones to fit? Has anyone got any experience with RHD headers, do they exist somewhere? Thanks.

    So I have been installing catless headers and started yesterday. Today I finally got the old oem headers off. Half of the manifold nuts came out without the stud, and half came out with the stud. While trying to put the new headers in, after 2 hours of trying to get the front header in I think a...

    I am installing headers in a few weeks and I plan to cut the muffler off as well... maybe the resonator too but after I see how it is with headers and muffler delete. Anyone have experience driving with headers and muffler delete? How F***ed is it really when driving in a quiet town at night or...

    I will be doing a header installation soon on my '99 328i after I get them coated. I have read about the nightmare of o2 sensor fitment and how people have had to re weld the bungs. I am going to get a tune later this summer and it will remove the CEL for having no post cat o2 sensors, so I am...

    Hi I have some stainless steel headers (Ebay :p) coming in the mail and once they get here I plan to either ceramic coat them myself (I've looked into VHT flameproof spray and exhaust wrap) or to ship them to swain to get them professionally coated. Doing it myself would save a lot of money, as...

    seen a lot of people doing catless ebay headers but keeping a muffler/ using aftermarket muffler or keeping resonators. my question is what would it be like to do ebay headers + a true straight pipe (no cat no mufflers no resonators) on my e46 328. Would this sound terrible? I want my car to be...

    Alright all, I’m at a loss. After nearly 10 hours at the JBLM auto hobby shop, I still wasn’t able to get a set of headers in. It seemed like a relatively straight forward job, but it all came down to a single bolt on each section that I couldn’t access. So here’s the question, do any of you...

    hey guys I got these ebay headers installed on my 2002 330ci by a shop that said they were bmw specialists, after a week to install them i pick up the car and on my 15 min in at my house it started misfiring in cylinders 1-3 along with those codes it also said something about the bank 2 first...

    Unfortunately the day has come when my cats have gone bad. From the looking that I've done, it's quite expensive to get these replaced. I was thinking a potentially cheaper solution would be to replace the headers with the Active Autowerke headers, as well as some after market catalytic...

    Hey guys I'm relatively new to the BMW world and I've just bought my first BMW, an E46 330Ci Manual '02. I'm looking to change my stock headers to something aftermarket and less restrictive. I've found some decently looking ones online but none of them strictly say that they'd fit a coupe. My...

    To remind the clueless… I think today, I'm going with Engine-ish Pt 2. Going with some non-CSL stuff for a bit. First up we got ARH Headers with cats. Cats are upgraded to GESi instead of the normal cats that you can get with them. The headers were also ceramic coated by Swaintech. Brand...

    So I've been around cars for a long time (started wrenching in the 70s). Wondering if anyone has helpful ideas to remove the exhaust manifold nuts. We want to replace the stock Exhaust with catless headers (I suspect the cats are plugged). BUT I cannot get even one of the nuts to break loose...
