There is no drone on a GPF back system on a standard vehicle with no other mods and we stand by that. What one person may think drone is can be different to another.
We have a customer with the worlds quickest kona n and he runs this system with ZERO drone.
Drone is not so complicated term as you want people to think it so cut the bullsh...t please.
I don't care your customers in the world, I care only my GPF back that I bought from you for £1100 and my Kona N, and my experience. And I know what is drone and Biscuit also knows it. He is selling it, because you couldn't, can't fix it. It's no joke, it's happening.
Hang on, Dan had a I30N and you have a Kona N. They are not the same system. So please disregard everything you’ve said.
Disregard? Why would I do that? Is it possible to make an exhaust for i30N without drone, but it's impossible to make it for Kona N? What are you talking about? Those 2 exhaust systems are basically the same (not very surprisingly), very similar parts, with different lengths and curves. Of course the drone frequencies are not at the same place but eliminating the drone is exactly the same task. You make the chaos here again try to make it look complicated try to talk yourself out of it. I'm a dipl. mechanical engineer, MSc.
Please cut the b...sh..t you're not talking to excited boyracer teens.
If you were able to attune Bushell's car you would be able to do the same with Biscuit's car. But you can't, you have no idea how to fix it. Actually it should be the same by default as Bushell's car (with sports cat) was, attuned one, without drone. You knew he used a sports cat, he bought it from you and he said that 1000 times.
Please think it twice what you say, it makes no sense, it's a bulls...ting and everybody can see that. And it's written, hard to change and remove especially when I cited it. You can't edit my comments.
The video you’ve watched it’s nothing to do with a Kona N. We have a very good understanding of calculating the Helmholtz frequency as that’s how the business was created as we successfully done it on many vehicles with over 5000pc of Golf R anti drone resonator deletes being sold.
Hahaha, this is ridiculous, you are a Helmholz expert, it is your speciality, and you built it for 1000 cars already, solved the drone everywhere in the world.
Except with Biscuit's and my Kona N. We are so unlucky. I'm envy at the 5000 Golf R owners.
"We have a very good understanding" - don't use the majestic plural if you are alone, it won't make you a serious man.
You should have fixed the drone long ago, or you shouldn't have sold a bad droning exhaust at all. Bragging with your non-existent knowledge won't help at all. If you had very good understanding we had no droning faulty exhausts, me and Biscuit.
Drone on his system is created by the extra volume of the sports cat, development is continuous with every single product as we are always striving to improve which is how it should be in todays industry. We cover all development costs
We have sold over 20 GPF back Kona N systems worldwide with great feedback!
Biscuit are you listening? They will cover your expenses! (just kidding, they won't). I'm sorry Dan you mentioned before that you'll refund £70 to me. In this topic, page 2 message #25, at the bottom.
Did it happen? No
You make promises, you talk, you chaffer, but you are not a serious person. You won't cover anyone's expenses or damages.
"Drone on his system is created by the extra volume of the sports cat" - OK, Biscuit this is your last chance! Please install the whole RPM system again including the GPF back, but excluding the sports cat. According to RPM Dan you won't hear the drone anymore, it will be gone with the sports cat, because that is the culprit.
But if you believe me the drone will be there, maybe not as loud as before, but still very loud and unbearable in long term. I had serious drone without sports cat. It's because of the nature of the drone. The drone is nothing else but low frequency resonance spots in the cabin, the cause is not only a loud sound source but the resonance itself. The resonance is a killer thing, search for Tacoma Bridge on youtube. Resonance makes it REAL loud, much louder than the source itself !!! You start to accelerate the car, and at some point your brain melts down, that is called drone.
You may be unhappy but we have offered to help you which you declined to email us, but the offer still stands!
Yeah, I'm glad you discovered that I was unhappy
And Biscuit is unhappy too.
I declined to email you? Awww, so it's my fault again. Always the customer's fault. We had a long-long conversation here a few months ago. Look at page 2...3. Other people ran out of popcorn and later they ran out of patience too. We talked about my problems enough. No, I won't send you an email about my exhaust and my problems, because I think it is not the reason you don't want to fix it. You just play games. Looking for excuses for the very moment. I'm a much more direct and straight person than Biscuit, he is polite and he avoids conflicting words. But the result is the same, at the end we both have unusable RPM Performance systems for £1100 and the seller blames us. It's not about the customer's style but the seller's will and knowledge. You can't fix it, because you don't know how, you are an amateur in this business, so you'll always find an excuse. It's not your fault. Until the customer gets tired of it and leaves you alone. But unfortunately we both lost £1100 and I think it's a good lesson to others.
I try to warn them. Guys! Avoid RPM Performance at all costs !!!
