    has anyone ever gave the chinese cans a go?
    some popular "named" lookalikes for virtually no money.

    i'v watched tear down videos on youtube and theyre is no justifying the difference, as fas as i can see.

    change my mind or enlighten me if you have seen a problem.  :031: :028: :173:

    The Chinese are masters at copying other companies’ products and often that ‘copying’ often only applies to external looks. Some cheap Chinese electrical goods are  fine examples of the dangers of these copied products.
    Good quality slip on cans from the likes of Akrapovic, Scorpion, Arrow, etc, are dynagraphed to suit the machine they are intended for which is highly unlikely for any cheap copy. This means a cheap can could possibly damage the engine through incorrect fuel mapping.
    I have a Scorpion slip on fitted to my bike. The can is specifically made for the VFR800, carries a lifetime guarantee, and comes with a certificate of conformity for UK and European standards and regulations. No re-map of the fuel system is needed.
    I would advise on purchasing a recognised and proven make even if they are more expensive.

    Must admit I tend to agree. UK/Euro standards and regs are there for a reason.

    I shall be purchasing a DAM for my trusty steed come the spring. I have one on the 1200 and the noise it makes.....well, I get so excited, a little bit of wee comes out!  :001:

    DAM good can, Skids! Ah well, I suppose you've heard that one before. I can recommend a good panty liner for those exciting occasions. :003:

    iv read so many topics on this , that after any sensor there is no difference with boxes only noise. the brain just adjusts according to flow pressure creating the note. 
    im a truck man on spanners, so bike stuff isn't my fortè apart from oil and chain and basic stuff, its all easy nut and bolt stuff.
     i wouldnt tempt valves, as i'd prefer i had a service receipt for that stuff too.
    points taken, cheap used might be a better option, iv never had a non standard can before in 35+ yrs riding, maybe i shouldnt change. keep it factory👍

    Totally agree Hanger, unless you change the whole system, lose the Cat and have the EMC chipped/flashed which isn't an option I've seen/heard of for the Dresser. Weight & sound are without doubt the only major difference you'll notice with an aftermarket can. Changes to how it'll run are minimal and easily compensated for by the EMS. so much so Honda make zero changes to the new bikes sold with Akro can fitted or claim any improved performance either.
    I'm not sure the sort of price you're looking at for a Chinese can but I've always found Delkevic cans nicely made & very reasonably priced too.

    Hmmmm  :084:

    Not sure I fully agree there m8.

    Honda end cans are designed to Euro 5 or 6 depending on when they were built. End cans can be quite old and therefore not iaw current Euro regs and therefore more likely, especially with spuds out, to be freer flowing allowing a significant change in the pressure patterns within the exhaust. The bike sensors will pick this up and adjust the ECU to cope within its current programming. Other changes will also affect this.

    All this can lead to noticeable changes to performance as well as the obvious noise & weight changes.

    On my 08 VFR800, I removed the PAIR system, fitted O2 Eliminators, removed the snorkel and blocked the flapper valve in the air box. Along with an aftermarket end can, and ultimately a full exhaust change, the bike ran better and better, much smoother at low revs and when cold and with a marginal increase in fuel consumption.

    The current Cr has a different ECU and meets current Euro regs but the engine is basically the same so making changes to any of the above should make a difference though they have ironed out a lot of the niggles associated with the previous 800 model so they're likely to be less obvious.

    All JMHO.  :031:

    Out of curiosity, Skids, have you done on your current CR any of the mods you mentioned that you did on your 08 VFR?

    No I haven't m8. Like I said above, they've made great strides in improving the engine performance on the new (15+) model Cr and the new (14+) F model so that it doesn't seem necessary right now.

    There is still some cold engine low rpm hesitation but I'll wait until I get the DAM before I consider doing any more.
