    So you fine folks that have upgraded your headers..... Where have you gotten them. And are you happy. I will buy myself a set in the next 2-3 weeks, and travel to Denver, with performance in mind. The trip will be documented in a thread here. It will include some airbox testing..... DJ pc-5 with Auto tune.....headers.......video's and pictures. In house at Sisneros Speed Works....... boy oh boy oh boy... This'gonna be fun.

    I put Remus headers on mine and like the hp boost and sound. However they are not compatible with most crash bars and skid plates. PKB

    I've got Quat-D headers: they are especially suitable for low-end and midrange torque increasing.
    Very-very efficient because of joint close to motor head, but if you don't provide with others (silencer i.e.) you're going to loose 10 km/h on top speed

    Pls look here in a temporary fitting with plastic skidplate:

    Mine wasn't OK with Alu OEM skidplate (modification required), but seems they changed design.
    One of our friends down here already faced this detail, talking with me... let's dig into the room.
    You can buy directly from the factory (ask for price) or from Twalcom.

    Others (Remus, Arrows...), with the joint as per original, are more for all-around the torque curve, but I do suggest these 'cause our engine is physiologically weak just on the average range of utilization: expensive, but good medicine, QD's. :evil

    +1 Remus Headers and canister. My only Modification is that I had the headers porcelain coated black to match the triple black theme.

    So the Twalcom headers looks like they are less intrusive, meaning they dont obstruct as much space as the remus. It looks like the sit flatter. Did you fit it with silencer as well...... if yes, no top end loss....???
    Thanks

    I do like the Remus, but I dont think they will fit with out mods to my bash plate.

    If you don't mind me asking, how much does porcelain coating cost generally?

    I had some pipes on another bike ceramic coated inside/outside and it was about $150.... But that can vary from region to region

    I have Remus headers. they are really nice and easy to install. They will not fit with any bash plate (that i know of) i dont think any aftermarket headers will....

    @ebrabaek: pls see here (posts 8,9,12 & 21) http://www.advrider.com/forums/showthread.php?t=698008&highlight=quat-d

    Regarding:
    I do confirm there's no top end loss with a more open silencer, but actually with this configuration you'll lose some low end snap.
    Careful: not torque, but only in "throttle reply", that's going to be smoother.
    ...all this with Quat-D silencer, that's equipped with a unic dB killer based onto a special fluid dynamics (pls see their site): very open indeed, therefore with a lower back pressure (affecting right low end snap).

    The best all-around silencer is Akrapovic, anyway.

    Within the solutions to re-gain top-end performance, there's the remapping itself. :evil
    I do suggest to try with OEM silencer, first: if you like that famous snap, couldn't be necessay to change silencer.
    Do you like overkill? go for Akra. ...anyhow, pls consider the psychological impact on a 1.2 boxer to become humiliated by a E8GS with OEM muffler... :rayof

    PS - info@qdexhaust.it ask Mr.De Liso (don't look the graph on the site: they're of another bike...:fpalm )

    Mine cost me $75.00, and so far has held up great. Sand blasted and coated inside and out. It was done by a Jet Hot dealer.

    Thank you for your explanation. I have a all Carbon Fiber silencer on it, and it will stay. My concern here, is that with such a free flowing system, it will rip through the rpm's like a racer, but loose some low end torque. All rider are different, but as I do spend a lot of time on the trail's..... That is important to me. I think Twlq, or Arrow headers at this point.

    Same approach: best with OEM silencer & QD heasers.
    With Akra you'll not lose low-end snap as per the average of aftermarket mufflers.

    Have a nice mod; the best is anyway remapping BMSK: with PC, if I do remember, it's impossible to play with ignition advance timing... it tells a lot and can compensate your carbon silencer.

    I would have prefers to reflash the bmsk as well, and since the pc-5 don't offer the ignition control. Specially. But it is what it is, and I am willing to yank it all off, if it does not go well. We shal see.

    Why not gut the cat to obtain free flow? Has factory look flows straight threw ,With no bash plate problems?
    Just a thought ..
