Harley-Davidson New 2010 Exhaust System

harleyexhaustsystemSomething I didn’t mention before is that it seems that all new 2010 Harley-Davidson models exhaust systems are now equipped with a catalytic converter. Only the 2009 models sold in California had them factory installed. EPA is after all manufacturers and Harley-Davidson is anticipating what will be soon, no doubt about it,  a requirement in all US States. So, it means all Harley exhaust systems running hotter? What about the warming of our planet…

    WHAT? Just more government intrusion,………. as if motorcycles contribute that much to the envrioment anyways…….? I mean come on, just how much can motorcycles contribute to the warming of our planet? Government would rather let a factory blow countless pollution into the envrioment while maybe fining them for doing so, and tell me where does that money go? Let the president appointment another czar that can advise him personally,……… Oh, that’s right he has a
    so called green czar,…… what’s his name Van something or other who has admitted he is a communist, and a racist, in the past calling president Bush a crackhead…….. Wake up America,
    …. before we starting spelling America with a K……. AMERIKA , at which time we will all be making the same amount of money, standardized healthcare, no more worry, the government will give you what ever you need……… Sorry Cyrill,…… just got carried away, but it being the Labor Day weekend and all, I hope that other people will wake up and vote these self-protecting types out of office………. Thanks again for the chance to comment on this subject.

    It’d be interesting to see a study of the energy and pollution created by manufacturing the catalytic converters and recycling the platinum, vs. the pollution they prevent. Anyone know?

    “…a study of the energy and pollution created by manufacturing the catalytic converters and recycling the platinum…”

    Wouldn’t do much good. Reality just confuses em………

    Motorcycle catylitic converters are more green “unicorns” to chase, like hydrogen fuel cell cars. The source of hydrogen used in them is processed from natural gas, a fossil fuel. Where will this dumb stuff end?
    I’m all for a clean world, but the ideas being pushed down everyone’s throat create as many (sometimes more) problems than they solve. But they certainly give politicos some nice catch phrases to ring in the ears of the ignorant masses.

    Some other countries contribute a huge amount of pollution to our planet like China and India and to a lesser extent our neighbor to the South. These rules may leave one with a warm fuzzy feeling here in the US about doing good but once one visits those countries and gets away from the tourist or government approved visiting areas it will soon shock you. I’ve been there and it has left me totally disgusted. Let’s see, more pollution controls, more cost, more fuel consumption, less performance, etc. There’s an old American saying “follow the green”. Carbon credits, some will get rich at the expenses of us worker ants.it’ll leave some with a warm fuzzy feeling but its all fiction. I’m going to stick with my old flatheads and fight all the way.

    Great point, Mike- China burns coal. China doesn’t give a rats-ass about environmental issues, their coal burns pretty much like it did here, circa 1910, unencumbered by any filters or catalysts.

    What gauls me is how ineffificient a catalytic converter really is; Effective during warm up, but after that, your fuel-injected vehicle will pretty much pass a smog check without a converter- mine did.

    So all of this money is spent- this cottage industry created- to address the first two mins of operation of a vehicle- nice. Platinum isn’t cheap or in endless supply.

    Fact is, one average forest fire dumps more hydrocarbons into the atmosphere than the SUM total of EVERY internal combustion engine built since the beginning of TIME.

    But as usual, it’s not about the facts- it’s about the political issue, and exploiting it to sway votes.

    I’m tired of hearing that I don’t care about the environment because I pull my cats; Fact is, I care MORE, because I bother to study the subject, rather than be told what to do by some zealot with an agenda.

    Yeah, a Harley with even HOTTER pipes- really smart…. BTW, has anyone heard about this issue with newer Harleys being the cause for starting fires lately? Had an interesting conversation with some Florida firefighters recently about this- seems the word is out in the firefighing community that there is an issue with home fires starting in garages because of recent models combusting…….

    Buy a new Harley and help prevent global warming.

    This is just like the Energy Commission ! The Catalitic Converter Commission.

    interesting if true,that one forest fire doses more damage than all engines since the begining,would like to see that fact,and show it to everyone.

    Euro lll standards.

    Will there be changes in the near future, tougher tighter rules/regulation.

  11. 11 fubar Sep 8th, 2009 at 10:25 am

    take them off. you dont need them. on another note you may change your mufflers to whatever you want since it will be downstream from the cat.. this will make all mufflers legal even in cal but for a noise issue in some areas. as long as its not too loud i think it will be ok since the absorbs sound on its own.

  12. 12 Pitbull Sep 8th, 2009 at 10:32 am

    Cats have been on various models for the past 4 years, just look at your mufflers and it willt tell you catalytic equipped, only on a few models like the baggers and softails.
    California emissions state that if the bike did not originally come with cats you can run any exhayst you want and still be legal, as long you you meet the sound requirments which I believe is 95 or 96 db. Now the charcoal smog can thats another story.

    To the question above, The following link may give some insight on the magnitude of forest fire pollutants as related to some of the rest so yes do not ride your bike if fitted with a converter in high grassed rally campgrounds.

    Forest fires especially those burning whilst clearing of the Amazon and mother natures volcanic burps as well as sunspots contribute to a larger extent then the exhaust releases but do not merit the attention of those who hype because of the lack of profit. The US just needs to go with nuclear power and natural gas with supplemental wind and some solar as the last two cannot suffice the needs by themselves. Yes battery power is here in its infancy and will come as technology and economics merit. That leaves the petrol which over time will reduce considerably but not in my lifetime so combustion is still mine to enjoy you young bucks will have to continue the fight for its continuance or just be content with historical mantle pieces.



    Obligations under the Kyoto Protocol are far more restrictive/burdening than the US Clean Air Acts, “as bad as they are”, that started in the 70’s and little by little are all phasing in/being implemented in the US, but pale in comparison to the EU/Kyoto protocols that has been agreed to and is coming our way.

    As stated above in a comment – one world, one atmosphere and the India/Caspian/Russian/Chinese and South American areas not being signed on to same clean air initiative makes all else rather pointless in the size and the extent of contributing concerns ???

    So even where issues are relevent everything is irrelevent in the global scope of things but even more important and relevent is that all is being driven/hyped by the few who are/will reap millions in financial gains off selective issues and the subsequent brother-in-law companies spawning off the hype and so called all in answers. Believe I have stated this before but didn’t that fellow called Gore, Al, that started off with a political fortune of only about $3 million only to have it balloon to over $300 million in a few caring years jet setting around the world hyping the global concern. We are such a shallow and naive nation/world that jumps on and off the bandwagons of the self-serving spotlighter’s. Do we need to be cognizant of the environment yes but do we need to bankrupt industries and alter ways of life that are contributive but not determining, no.

    What will this mean for the future of bikes without converters? California has been trying to pass SB 435 and has recently failed to have it passed. But I feel it will not last long. Should we start looking for stock pipes?

    “…Why is this not a major concern for more people?…”

    Could it be because too many people think our Republic will keep operating even when a significant portion of it’s citizens opt-out of the political process…… ???

    How’s-zat go……. “Don’t worry, be happy” …… “I just wanna ride”

    This will help finish off Harley sales in a deep recession! The cats make the bike’s run hot and are uncomfortable to ride. They were hot enough because of EPA regulations, Harley leaned the AFR, Air Fuel Ratio out so lean the bikes were already running hot. An Air Cooled engine does not like to run lean, then they hung the cats on them. No help from Harley with the heat issue either, told me to take my lower fairing off in the summer.
    The bikes are underpowered and hot because of the catalytic converter added to all 50 state biked form 2010. I bought a new 32,000 plus Tri Glide and it is like riding a stove top. I had not planned to buy a new bike and have to fix it on my own.

    Just like the old AMF days, selling bikes with problems and telling the customer’s you are on your own!

    Harley has been installing cat converters in the slip on muffler section of the stock bikes since the mid 1980’s its no new thing the only thing differant now is the cat is inh the head pipe making it harder and more costly to remove and replace
