Early 750 Stock exhaust discussion?
Does anyone think there will be more made in the future? I didn't really want one when they were lower priced, now I have the sandcast, I'd like to return it to stock.
Buuuuut, I'd hate to have to sell a bike to buy mufflers.

Edit: I did sell a bike to get Yamiya's and never regretted it. Well, maybe a little.

IMO Don these stock HM300 and 341 pipes make these bikes and with out them they aren't quite the same. I have a 4-70 750KO that I bought in 2011 and it still has the original 300's, but are showing their age and I have had to do some minor patch work in places. Now since they are discontinued from Honda I wish I had bit the bullet and bought a new set when I could still get them. Well should of, could of, would of I guess. Now I'll just have to run the original ones until they completely rust out. I've had 3 HM341 pipes for several years and been trying to get the near extinct #2 pipe just like quite a few other members here are. Last week on ebay a near new #2 went for $685.00. I need one bad, but I not going to fork out almost $700 bucks for one f#%^ pipe.
To answer the question, No I don't think Honda will offer them again. I think their done

Im sure the top dogs at Honda aren't to concerned about parts for a bike that's 40 years old. This bike set Honda and the Motorcycle world on fire in 1969 but in 2013 it doesn't pull a whole lot of weight.

Don, I also doubt they will manufacture the pipes again. The cost to set up the tooling and the very limited market would prohibit that, in other words it would be a bad business decision...Larry

Member Johnie got very lucky recently when he bought his low vin die cast that had the elusive no stamp early pipes. Those were the original ones on the Sandcast, guess a set of HM300's would be almost as good but I believe the early first gen pipes were different internally. I have not looked but doesn't Yamiya sell those 'sandcast' pipes ? Seems somebody was. Not sure if they have the EPA crap stamped on them like most repops. If you got a great deal on the bike you can maybe justify the price because it will increase the value of the bike if a mild restore is the plan.

Correct Eric...I must be living right to have those no stamp pipes on this 10/69 build. So nice to be doing a bike and not have to worry about finding the exhaust. I agree, Honda is not worried about the vintage guys and doubt they will be making any. However, you wonder why they supplied then to us for about 40 years in the first place. I suppose the terrible workmanship regarding the poor chrome and fit on many of the 300 & 341 pipes may have had something to do with it. These bikes just do not look true vintage without the 4-4 on them. I really think someone will be making them again. Yes, Yamiya has someone making the no stamp pipes. Many times I see they are not in stock just like DSS, but looks like if you have the cash you can find them.

Yamiya has the lotus root pipes listed for 262,500 yen, my computer doesn't like drop down boxes right now so I can't convert but thats around $2,600. I was under the impression someone other than Honda had made a run of the original pipes and that's where all the ones sold the last few years came from.
But I could be wrong.

Don R · « **Reply #6 on:** October 31, 2013, 08:27:56 AM »

I know how to get a production run made. I buy the expensive ones and next week they'll be selling for $1200 again.

Yamiya 'no number' replica pipes were available when I looked last week. A new set of those is about $2K shipped to the U.S.

HM300's are acceptable for a restoration, especially if they're the 'no paragraph' pipes, as in they're original from the '70s. I have a pretty nice set of those I'm going to use when my sandcast is 'done', and I'll buy the Yamiya pipes if I go to sell, because it really does make a difference, and my 300's aren't perfect. If it's for you, just try to buy a nice set of HM300s separately, or together and save a grand or more.

The Yamiya pipes are no-nos. Meaning, they have no stamping of the part number or the emission paragraph. They are nice, but they are pricey.
They seem to be about the only one that as them at the moment. Every now and then there are good used ones on ebay. I believe the seller is firenbriar. I'm pretty sure these come from Vic World's legendary stash of CB750 parts. I have bought a few, and while they are not "show" pipes, they are always VERY, VERY SOLID and darn fine pipes - even close up. I know that Vic doesn't mess around with trying to fix those old pipes - just never works out. Not sure who it is that is doing the selling for him

Every now and then I see some re-pops from Vietnam on ebay for around $1800. More and more it seems like that is going to be a decent deal. Just makes me leary buying something from those parts of the world. Communication is always hard when you don't speak the language.

I too believe that eventually somebody is going to have a connection to someone in Vietnam or china and start re-popping them again. However, I think that the price will be higher than the good 'ol days. Probably cost us $1500.

Hard to believe - but, just 6-7 years ago when the English pound was taking a beating, I bought 2 sets of Genuine Honda pipes (a set of 300s & a set of 341s) Both sets to my door in Texas, from DSS in England cost me $1760 USD - shipping included. I wish I had bought more.

Ah yes, let's not talk about how much more we should have bought during the recession

Yamiya is out of the "no-no's" right now but says they will be back in stock soon. Pretty sure Yamiya is getting them made by the guy in Viet Nam cause the Viet Nam guy is out of them right now as well and he makes them. Yamiya's total with shipping to the US is cheaper than the Viet Nam seller. Also, I get orders from Yamiya in a couple of days where orders from Viet Nam take a month or more.

Would someone have to get licensing rights from Honda to produce the pipes?

Guns_Up · « **Reply #15 on:** October 31, 2013, 05:02:25 PM »

Just to add a little tangent to this thread for a second, if you take the megaphones off the pipes does anyone happen to know the ID and OD of the pipes for a 4-2? Im working on a little project but the bike is away from me right now

Thanks
Tony

Come to think of it, I never owned a stock 750 exhaust. My 500 was new, all the 750's have been used.

Ten years ago I found three brand new 341's hanging in the rafters of a scrap steel building, the guy said the fourth was ruined using it as a pry bar.

I have two spare sets that are perfect except for 2 decade old yellowed chrome. When I find a chrome shop that will deal with the carbon issue it'll make then like new again.

I've heard stories about back in the day these factory exhaust( brand new pipes at times ) were took off bikes and replaced with some type of aftermarket pipe setup to reduce the bikes weight some and to try gain a little HP. And in some cases these original pipes were just thrown to the side and trashed

OUCH!!!!

Quite true, many of the sets were replaced with 4 into 2 or 4 into 1(why? to be

8)of course) and thrown away

... I probably did a half dozen or more where I worked

Around here, if you rode in cold weather they rusted out in a couple years. The former shop foreman at our local Honda shop took two pickup loads of takeoffs to the scrap yard. They were hanging on racks that covered two walls.

Personally I think it's a shame if you allow the first (pipe) part of the exhausts to get rusty. That part is very easy to keep in good shining order and they hardly if ever rust from the inside. When I removed my original 4 in 4 after some 75.000 kms the pipe part was still as new and so I got € 100,- for them. The muffler part is a different story. No short rides is the remedy. BTW, I'll see if I can put some pressure on Honda... I have a cunning plan, but it might take a wile.

A cunning plan, huh? Maybe a class action lawsuit

? Honda is depriving us of our right to enjoy our old bikes. Hope your plan is more has more merit than mine

Sometimes cunning plans need a group of people...or group of E mails. I am sure many of us would be willing...
