I'm giving definite thought to buying the version with the two single digital displays. I've thought about these in the past, but your post on them reinforces my thoughts. I think you should definitely get them, but consider upgrading to the digital version because there's NO guess as to the exact temperature for either EGT or CHT.

Great find.

I use the common sense theory. Nearly everyone that makes headers has copied SS design. I think there is good reason to why they did this. I would assume it's because it's the best design for these cars. You don't see 10000 venders copying teknic gen 2s? or 3s? Or making their own equal length headers. I almost bought a set of very expensive headers that weren't SS based designs. Then I had the thought process that I explained above. The best header design has been out for years and copied thousands of times over. I doubt during SS R/D they decided this was good enough. They make imo some of the highest quality exhaust on z planet I also realize they have revisited some components and improved on them. You need a very large amount of capital to do all of this. I don't think the other players have that ability. What do you think? I will have a set in 2 days, at that time I will write a detailed review of the BB headers vs ebay headers etc.

Ya that makes sense, I was under the impression though, that all the ebay headers are supersprint replicas? Aren't the BB headers just ebay headers that are guarenteed to fit?

Your terminology is off. Everyone copied SS headers. BB are not ebay headers. They are BB headers copied from SS. EBay headers are ebay headers copied from SS. AA headers are AA headers copied from SS? Still confused? PM me, I will write you a short novel.

Nope not confused, just possibly incorrect, but once again...
As far as I understood, BB headers are simply ebay headers that have been "re-badged", "re-distributed", or otherwise "re-marketed" as Bimmer Brake's headers and are literally from the exact same manufacturers as the ebay headers, they simply come with a guarantee of correct fitment.

I guess we will find out after your comparo. Correct me if I'm wrong, that was just what I understood to be true of Bimmer Brake headers.

*Edit*
Just found this thread, http://forum.e46fanatics.com/showthr...es+ebay&page=4
Seems like they are slightly different if not simply modified ebay headers. I'm interested to see if there are any gains to be had. Wish there was a dyno comparo.

^Nah your wrong. Buy a set of eBay headers and BB headers. Compare the welds, fitment, & craftsmanship. Then you'll see that they are nowhere close to the same or from the same manufacture. They haven't been modified in anyway. The O2 sensor bungs are in the correct place and haven't been repositioned like most eBay headers need to have done. Hands down BB headers are the best bang for the buck when it comes to Non M headers, period. Anything you've read about them being rebadged eBay headers are from someone who's never held them both in their hands to compare.

Good to hear, makes their price more justifiable. My Ebay headers went on without a hitch, but if the Bimmer Brakes headers make more power I'd be intrigued.

Idk about more power, but the quality is definitely worth it. Don't have to worry about the crappy welds and such. The price is very justifiable consider the price of AA headers and Gen2/3's.

Oh absolutely the price is reasonable for a standalone quality header design (based on supersprints). I just didn't think it was reasonable before I knew they weren't just acting as middle men and marking up selected ebay headers by 400%.

I guess I just lucked out with my ebay headers though and power gains would be the only reason I'd switch them. My ebay headers had decent welds as well.

In terms of considering the price of AA headers or Gen2/3's. Those things are the most overinflated consumer infuriating exhaust pieces I've ever seen. In the case of the gen 2/3, they are trying to pass way too much of the cost of R/D onto the customer way too quickly. They need to be patient with their pricing and I'm sure they'd sell more long term. The AA's, being replicas of super-sprints, have no excuse for their price point. I don't know what to even think of AA as a company anymore. I used to aspire to buy their products, I personally have moved on. You'd think between the two of them that you were buying performance exhaust for a Lamborghini!
