    I have a 04 ci with clogged cats so I’m taking it as a good excuse to get some aftermarket headers. Does anyone recommend any that they have or had? Something relatively cheap and that will last?

    Alright so my last exhaust post got 0 replies, and I understand that its all subjective and at the end of the day is just gonna be whatever I think is good. But I still wanna throw it out there incase one day someone else wants smt similar. So at the moment I have headers and a stock exhaust...

    I got some catless headers for my 330ci, the gasket that comes in the set is pretty shit. Just wondering what gasket to run. I have seen where the oem gasket makes it harder to install the nuts on the headers due to the heat sheild. I have also seen that I could run oem m52 gaskets. Thoughts on...

    I am looking to buy a new headers for my 02’ 330Ci and I found this kit from vacmotorsports. I not sure if it is any good, I don’t know what to look for when looking at headers but I do want a high flow cat and this doesn’t seem too bad. Any thoughts or opinions on this before I buy? E46 non-M...

    In a pickle. One of my cats is going on my stock US-spec E46 M3 and thus the inevitable "upgrade" to Euro-spec ensues. Issue I am having; while I got a Status Gruppe Section 1 with high-flow cats, I am unable to get the BMW stock Euro-spec headers until December (backorder everywhere). Ebay has...

    Hey all, looking to get a set of castles headers installed in my beam machine. Does anyone know of a shop in WA that can do it for a reasonable price? And before the DIY gang gets on me, yes, I tried and it took me 9 hours to realize this isn’t a job I can do.

    Looking for quality catless headers, seems like everyone recommends BimmerBreaks but I can't find any for sale. Any recommendations? I really don't want eBay headers

    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...

    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...
