    Depends what your trying to achieve?

    Power wise the standard system is very good ... even the high end exhausts are not going to see a gain of more than 3-5 bhp @ peak ...

    If you go for a slip on you will more than likely lose bhp but the noise will make up for it :D

    @deano69 just stick with the original one, disconnect the servo valve and fit a powerbronze carbon sleeve.

    True, without a Power Commander.

    I gained 4bhp over standard and more midrange with PCV + custom mapping + Yoshi R77.

    With just a slip on you wouldn't even notice any power difference up or down,only when you go for a full system do you really need a power commander.

    Not at all.

    The standard downpipes are very very good, so a full system is going to make very little difference compared to an end can with standard downpipes. IIRC the main reason for changing the downpipes is weight over the standard stuff.

    Any end can that removes the CAT and EAGV ideally requires a power commander and O2 eliminator to get the best from it. Yes, it will run without but it will feel harsh and you will loose power... hence the Honda official Akra has both a CAT and EAGV.

    As an example I put a Yoshimura R77 on to my bike, and it ran ok but felt rough... stick the power commander on and you can see why it did ... the bike runs very lean low down. In fact 20-30% extra fuel is added in some places with my custom map.

    174bhp @ rear wheel, 86lbft torque with a lovely smooth curve mapped by FW Developments in Preston (Dynojet UK) is the result. Not a bad result either.

    So yes, you will notice a difference if you fit a power commander and it is wise to do so even with just an end can.

    Agree,but most people who fit a quality end can would only notice the difference on a dyno,so spending another £500 on a pc and map is prob something that isn't necessarily needed if pennies are tight,especially with the extra premium your insurer will charge.
    Yes,there are some on here that that strive for perfection and need or want every ounce of power on track,but saying that if you fit an end can you have to get a pc and map isn't true.

    It's more than just power ... It's ensuring the bike is running properly and is not running lean. I did mine simply as without it the bike was a dog to ride.

    You don't have too but why do a half arsed job... Do it right first time.

    I suppose every exhaust and bike is different and I agree that if the exhaust causes that much issues with the fuelling it needs sorting. I've got the scorpion on a 2013 and there's no issues with the bike. Yes a pc and map would prob give me up to 4 bhp,but really,500 quid for that. Most people would be better spending the money getting decent rubber,suspension setup and a lesson at a track school.
    All I'm saying is that people shouldn't be put off buying an exhaust thinking they have to get a remap.

    The 2010-2011 fueling is shite low down until you plug in a power commander, hence why I did the exhaust as well to gain maximum benefit. If you can get away with running without one that's fine, but a dyno run to check the fueling is a wise idea otherwise you'll never know if it is running right or not.

    Just go for one you like the look of, if the power of the Blade isn't enough for you on the road then you've got problems.

    Generally the smaller the can the louder it is. The larger ones with baffles in are barely louder than standard but get something like a Racefit or Two Brothers like I have and you'll wake the dead.

    If you're doing track days probably best to go for the former, if you're a chavvy hooligan like me go for the loud :D
