What's a "lug around at first"

I'll make a video next week when my exhaust arrives, but I have no idea how to do video editing. Gonna borrow someone's video cam.

Go kinda slow a few times thru the 1.5-3k range Kinda of scared about excessive resonance after hearing the encore. I couldn't deal with it. Thanks so much.

I did not know so far that you have such strict emissions in HK than we have in the US?
I got my exhaust from Ralf in Germany, you can get hold of him here :

info@krenzer-performance-parts.com

I guess one from the post in Singapore got his one also by him.
It was a very smooth and absolutely quick transaction, can highly recommend.

Current lambda adapters are throwing a CEL with some or most US cars. Not sure what the issue is. I never had lambda adapters installed in my car as I went for a full custom tune even before my exhaust is in. My tuner simply reduced the sensitivity of the O2 sensors so it wont throw a CEL. Once he is around the area, he will retune my ECU and DCT. Damn, the car now feels like the gearbox has to catch up with the engine.

Checkcaptain, do you know why some US cars are getting CELs with the Bonalume adapters and if Akra has a fix coming?

Please understand, that I will give no further informations on detailed technical questions - I do not want to spend another month on an island!
Suggest to contact your Akra vendor - he should know the same like me

To be very honest, I find it amusing that Akra is obligated to fix the CEL light occuring on those stock cars. Clearly, almost all cars stock will throw a CEL light when you go catless or High Flow Cats. Only difference, is ppl like AA sells the tune together with their pipes which makes it a one stop shop. To be most frank, I would not want to put those adapters on my car to fool the ECU from thinking I have cats. There might be other things that the O2 sensors control which I do not feel comfortable with. If I were you, I would get a proper tune for this system. There is really no point getting a system like the Akrapovic without tuning as only with the tuning will you find the optimal gains in which these system is designed for.

I am running a full custom tune for my ECU and DCT. There is 0 CEL light to date and the car just pulls VERY hard from 6K rpm. You only will see the proper gains with HFC only with a proper tune. The stock standard ECU doesnt make much power and I found that out for myself when I was on-road with the tuner tuning my car. I gained 27hp from the old exhaust setup. When he comes again and retunes now with my full Akra setup, I believe the car will be even faster.

I hope no one takes offense to this but based on my experience, a good tune should complement the Akra system. And trust me, it is worth it.

Amusing to you perhaps but not to those who bought on the premise of no CELs. Why shouldn't they provide what they/vendors are promoting? It's quite simple. If one wants a tune then fine, but for those that don't it shouldn't be a requirement unless advertised in such fashion.

Did you get adapters? If so then you paid for them. Shouldn't something work when you pay for it?

Not to mention the additional cost of software and increased risk of dealer hassle.

I did not get these adapters because I am on a custom tune. Definitely something should work if you pay for it but what I am really trying to say is that those adapters dont look too stable to be run on cars like ours. Its a mixed bag. Some cars will work and some dont. If you know, different cars have different ECU softwares flashed. Those running the earlier ones may not throw a CEL but those on the later ones might. BMW does more cycling of checks on the cats/emissions on every new software released. Same thing with the 335 I had, even with high flow cats, I did not throw a CEL when I was on Progman 25. Those who had progman 27 and above, had the CEL light thrown and both cars were the same cars with the same modifications.Even if they do fix the problem with revised adapters, I am sure that with later updates from BMW, you will throw a CEL. Softwares get very advanced with each revision and it is not a bulletproof modification that can indefinitely prevent CELS. Thats my point here.

There is a risk with the dealer hassle but to me, thats not a problem. Thats subjective to some. Yes the tune is additional cpst, but its the cost you pay to run a great system like the Akra and get your car to peak performance. And it also depends on the tuner who tunes the car. I drive my car really hard and there is no problems. If you go with big guys like AA for the software or other distinguished tuners, there wont be any problems. As you can read from those who have the AA software, none of them are having issues.

Just my 2c.

A "tune" or adapters makes no difference. Either choice you are still messing with the O2 sensors

Sorry but i have to disagree with that. A proper tune enters directly into the ECU and adjusts how the ECU reads the O2 sensors. Yes you are still messing with the O2 sensors but it is a far more bulletproof way than just adding an adapter and forcing the ECU to think there is a cat. Over time, with newer software, you are bound to get a code. More often than note, if the tune gets overwritten with newer software, you are screwed as well. But of course that's not the subject at hand now.

Guys, I can say from experience that the German HJS high flow 200 cell cats included in my Fabspeed exhaust DO NOT CODE. I have zero codes. Please do not say that all high flow cats code. This is false.

The Akras are 100CEL.

True, but no matter..... They are after the O2 sensors!

Software tune for sensors does not adjust them or make them read differently. It turns them off entirely and your ECU no longer can read them. Weird to have the computer have an empty value in the ECU all together. Its better to use the adapters in this case so you could somewhat still pass emissions is ever needed
