    So, does anybody have any comments (silly dumb fuckin question I know) or experience with either of the two adjustable “on-the-fly” exhaust systems? I want to know if anybody has used them and if you got through EPA testing, or through roadside pull overs etc. thanks guys.

    Have you looked at the cost of these?!

    Yip. They pretty expensive but maybe worth the hassle in the long run if I’m gonna avoid the dreaded canary!

    Not seen these products before so I hope you get some responses. Considering the cost, as a Dyna rider I was disappointed to see they don’t offer full systems.
    Dyna headers are crap.

    I think they do, they have a new configuration tool. Apologies if you checked but I thought I saw headers for the Dyna.

    Muzza I don't have experience with either of those options but I did have another similar exhaust, a patriot defender. It had a movable flap to adjust sound and flow. The flap was rigged up to a cable and lever on my handlebars.

    It worked very well and achieved my objective of being able to be stealth in a moment. I used it to start up and ride quietly out of my neighbourhood at dawn. 

    Eventually the carbon build-up in the exhaust made it difficult to move the flap. I think if you were fastidious in moving the flap very regularly it may not jam up as much. 

    I eventually sold it for another pipe but mainly because I forked out $ on a 107 top end build and to get the most out of it I wanted a good performance exhaust. I used the supertrapp 2-1 exhaust at the recommendation of the engine builder and also the tuner. It also conveniently happens to be one of the quieter exhausts which you can tune for flow/noise by adding/removing discs. They also have a closed end cap option which makes the sound very quiet. 

    The jeckyl and Hyde exhaust was around when looked into this as was the peacemaker but both were/are very exxy and I couldn't justify the cost for something that was relatively unknown..

    The concept with these exhausts is clever. The flow between open and closed is very different so I'd recommend you only change the flow/noise for when needed as otherwise your tune is out. Unless you had a power vision or similar where you can readily change between two different tunes. 

    The risk with the flaps that open/close/move to make these exhausts work is that they fail or jam up whilst operating in a very hot and sooty environment. I'd be pissed off if this happened for a costly exhaust. 

    You can avoid the risk of being defected via other means. My supertrapp and choosing where and when I make noise has helped me. 

    Good luck and let us know what you do

    Thanks Fatbat, I did see your posts from 2012, I think they were. I have FP3 tuner so on the fly reconfiguration of the ECU is not possible, I’d use the quiet option only when needed, to avoid annoying my neighbors and the cops. Interesting that the butterfly valve got chocked with carbon though!

    Seems like there is, for once, not even a sarcastic interest in this subject, which to be honest surprises me considering the shit we face with noise all over Australia!
    What’s up with you PB? The nominated cunt of the forum suddenly gone quiet, maybe you not a cunt after all! Lol. You know where that came from!

    BTW Fatbat, Jekill & Hyde do offer an extended two year warranty which makes me feel they serious about their quality and the products longevity.

    I hadn’t heard of them. Looked them up and look good. Until I saw the price. When converted from euro to aud, a pair of mufflers was $3,800 aud.  And that’s not including shipping. That’s the problem with some of these products. German products make a habit of this

    I understand why you are looking at these options Muzza, I admit I haven't really given them much thought but if you do go this way try, as best you are able, to get something that does not hurt performance when in the open position, as FB said, supertrapps with the discs are surprisingly adaptable with the available end caps, I'm currently running 18 discs and an open end cap opened up slightly and at part throttle it is (well I consider it to be) suburb friendly, open the throttle and it's a completely different story. I don't want to tell you how to suck eggs but every engine has a sweet spot baffle size wise and sticking with that means getting the most from the combo, if you do engine mods obviously that factor can and probably will change.
