    Well it's been fitted....
    My impressions are fairly insignificant compared to Kevin (the owners) but I'm sure he'll chime in soon.
    - Silencer is F**KING small -looks lost in the engine bay - reasonable weight loss over standard... (muffler weighs 8kg).
    - it does away with the fixing bracket behind the rear bumper and bolts to the gearbox! (so more weight loss)
    - It looks like a race item.. not pretty.

    Sounds:
    Interesting.... not as immensely loud as we had expected but then the CS runs a muffler bypass valve so the stock benchmark is VERY loud anyway.

    At low rpm, it's lovely - the stock CS is still a little bit "sewing-machiney" before the valves open and little agriculural. Well with the NGT Tubi its a LOT more racy and deeper - more aggressive - almost as if race mode and valves are always open....and yet strangley NOT too loud either... nice.

    At WOT There are two *KEY* differences IMO with the regular CS system - The NGT system does away with the silly non-linearity of noise the stock CS muffler gives. There are no valves on the Tubi so the sound builds and builds to a pleasing crescendo from idle to the redline instead of getting the explosion of noise when the valves would open as per the stock system and getting NOTHING when they're closed.
    At WOT it is every bit as loud as the muffler bypass channel operated on the stock system.... despite having exhaust flow channelled through a muffler...
    The second KEY difference is that the system has one extra layer of noise over the stock system.... a slight but discernible howl... it's like the stock exhaust note has been "cleaned" up and made ever so slightly more musical.. WITHOUT losing it's rawness (especially evident on low rpm downshifts - a little howly woofle type noise (my God - how sad am I :) ) )
    When we recorded it, the system was brand new but this "howl" was definitely there and getting more distinct with every mile
    All in all, I think it's a good product (yes I know I sell them but I'm not a bullsh!tter...)
    The stock system is tough to improve on and the differences between it and the Tubi NGT are all reasonably small....but in terms of small size, lower weight, much nicer low rpm noise and a slightly *sweeter* WOT noise, the Tubi NGT has the CS muffler beaten... A nice way of adding a little bit more to what is pretty much a perfect car.

    Power increase?? - Can't tell - didn't drive it (owner asked but I'd rather not)- Kev will have to tell you if the car felt any different from the butt-dyno.

    Videos are going to be on our website in a few days.

    Kevin - what do you think?

    I have not heard the Tubi, but Sunday I heard 2 Stradales. One had a Capristo and one was stock. The sound of the Capristo blew away the stock sound in my opinion. Sweet

    manu- do you know of the Tubi NGT crosses over the exhaust between the two banks? The 360 IIRC does not in stock form (one of the reasons the 360 sounds broken compared to the 355 in my opinion.)

    Hey Manu, I was too busy playing with the car to post on here dude! Bottom line is it's just FANTASTIC and definitely a keeper. The Hatfield Tunnel test was that last hurdle and it was just epic through there.

    I haven't analysed it in the same way, but my impressions are:

    1) At idle there's not much volume difference with the stock system. This is a godsend since it means my neighbours can hold off with that restraining order and my ears don't bleed when sat in traffic.

    2) At 1-2K the sound is louder and deeper than stock, and quite menacing.

    3) There is a bit of deep resonance at 2.3K.

    4) At 4.5K it starts howling as well, sounding much like a 360 Tubi.

    5) At >4.5K you get the Stradale note overlaying that Tubi note, but it's MUCH harder edged and distinct, like the sound has been cleaned up. The sound is less 'trumpety' than the stock system.

    6) All the way up to the redline you get hard-edged Stradale/Tubi blend.

    Through a tunnel it's just fantastic. Even more satisfying than stock, and that was pretty damn immense to begin with. The exhaust note is more complex and interesting, and you really can play it like an instrument. Butt dyno says the car revs more freely than stock. Bloody amazing. Other owners will know just how significant that last statement is.

    You know Manu, when Ajay did the Maranello flypast with the stock system I was a bit doubtful we'd improve it. I can well believe the Maranello guys thought it was already an aftermarket system. I mean it's not like a stock 360 where there's obviously room for improvement. Amazing that we've managed to do it. Shock horror I have to work today but will try to get a pic of the system in the engine bay later on.

    ps WTF is 'WOT'?
