the problem with an open wastegate, which I have had in the past, is that it greatly restricts your use of the car. It may not seem like it at first, because of the novelty of it and the kind of driving you do initially on that kind of build. Later on you realize that a lot of passengers don't want to ride in it because it's so loud. Then you realize you have to be really careful about attracting attention from cops, or angering other people around you on the road or in neighborhoods. There's also the concern that you can literally damage your hearing from the noise if you're not careful.
So the novelty wears off, and you start realizing the downsides. You get tired of all the above concerns and try to avoid them, and eventually you realize you're not driving the car as much as you want to. So you come to your senses and merge it into the downpipe. Or you realize you're sick of the car and you sell it.
I've seen it over and over again over the years.

I like the sound like this and I don't want for anything in the world to reduce it or even remove it, and I'm even looking for the opposite, hence the subject of this topic...
I know people who clearly dont like it and reroute them in the downpipe, but they have a straight pipe exhaust at the end. I just prefer the other solution

What we have here is a failure to communicate … to you what’s obvious to the people who are more experienced than yourself.
What you described in your reply to me (not bothering to copy it) is exactly what I stated. It only happens under that certain condition. We get that you think it’s enjoyable and that you don’t want it to be loud all the time; it’s very obvious. You don’t get why we’re not agreeing with going there based on our own life experiences of been there, done that. Comments like “killjoy” and “grapes” reveals more to us than you recognize.
Let me try to get through to you again; if that’s what you want then an actuated butterfly valve to bypass the exhaust system and dump the downpipe to atmosphere when the wastegate opens is the solution to your “enjoyable” goal, i.e. twice the scream. That was the served on a silver platter answer you were seeking.
Yet it wasn’t heard then any more than you’ll be able to hear anything else later in your life. Don’t get upset and think you’re going to show us something with some snappy come back reply. Instead, just go show us how it’s all fun and games without any payback doing it your way. Because anybody with half a brain knows that a bunch of dumb, ignorant boomers got nothing on the superiorly advanced youth of this enlightened, tech-savvy generation.
Reminds me of Christ’s words; “fools and blind”. Except from the earliest known Greek texts this more correctly translates into English as “morons (μωρός - moros) and blind”, but some people aren’t as aligned to truth as they may believe. So let me spit some real truth out your way; nobody on here was likely as big of a moron at your age than myself. So what someone like yourself doesn’t often get in these type of situations is that the critique is not so much on you, but on myself trying to help you from being one too and then having to live with it later. It’s absolutely your right to be and do if you insist though.
Go have your fun already.

obviously we do not share the same way of seeing things. The first answers to my original question were very constructive and pleasant as far as possible. unfortunately, it quickly got out of hand and inevitably drifted onto another subject which is much less so.
On this point, I will add that I do not really think that your first comment is really essential. what I see here is more of a demonstration attempt in relation to a supposed age (experience) that you have on the subject, which is to your credit. But even on this point I allow myself to disagree except to take into account what you tell me.
No need either to argue using the us for the group effect and the acceptance of your friends in order to make me believe that everyone is of your feelings.
I only keep the first answers in account made by the first ones which were interesting beyond the psychological aspect.
Good for you the great life lessons on a car forum.. it's your point of view but I can see the kind of person you try to represent in real life, once again good for you.
no need to answer me, I got what I wanted and I thank the first people. the time has come to disconnect. best regards

OP why don't you go buy 3 wastegates with 3 different sizes, 3 different screamer pipes for each , get some accelerometers and microphones and evaluate the sound difference between each setup? We all know you have a loud screamer pipe, and we all know you want to know the sensitivity of the NVH to the gate and pipe design. So do what other people have done when they are curious about something and study it yourself. We've already explained why nobody else here has bothered to do such a study.
At the very least, mount a microphone under the car and look at peak decibels with multiple different wastegate and pipe configurations. That doesn't require much special equipment or software.
So you need:
1) a baseline or control test, maybe with the wastegate already plumbed in. bonus if you can get data from somebody's stock FD.
2) current configuration
3) current configuration but with different length screamer pipes
4) configuration with different sized wastegates (might need adapters to make it work as I doubt you want to buy multiple manifolds)
Post sound clips of each one, and the acoustic waveforms (FFT), peak decibels.

Firstly should I see this as a challenge?
it starts with a simple question. secondly why do all this when I have already got what I wanted?
Appart from wasting my time, I don't see the point. once again your last intervention was too much (it must be a bad habit apparently)
