Looking at getting these Jardine 4 into 2 exhaust for my 78 CB 550K.

I've seen one comment that concerns me and that was about interference with the front fender and another that exhaust should only be paired on 1 & 4 and 2 & 3.

Any opinions? I can get them for $200 CDN pesos. Worth it or not?

Thanks for any help, dj

Most of the fender clearance issues I've read involve bikes with modified front ends.

Can't beat the price and dual pipes have a nice sound.

Thanks Mann!

You in Calgary? I have a really used set of 4-2 pipes I would let go cheap if interested. Obviously it would give you an idea if you would like it or not

Darren Jakal · « **Reply #4 on:** October 31, 2016, 08:46:02 PM »

Hey firebane,

yes I'm in cowtown. How really used are we talking? I'd be interested.

Let's say the head pipes are good but where the muffler attaches is a bit butchered cause of lengthing.

Pm your email will send pics if you want.

Jardines are nice. Great sound on my 350F

Thanks for more comments.

I'm waiting to hear back from the seller but I will grab them.

A forum member has also made a generous offer and I'd like to say that I really appreciate the gesture and this place.

cheers, dj

The Jardine setup, is what I am running on my CB750K. Sounds pretty good and it was on there, when I got this one and while I may change later on, got other things to do to it first. Like a nice 4 into 1, but, for the time being, 4 into 2, will get the job done, nicely.

Darren Jakal · « **Reply #10 on:** November 02, 2016, 10:13:58 AM »

Good to know Bill.

I was on my way to pick up the Jardines when I checked my messages and found that the guy had to change plans.

Anyway, went looking for other parts as I have some time to kill.

later, dj

That guy sounds like me, never know when something is gonna pop up and require attention, when you least expect it. Hopefully, you can pick up that exhaust soon, and get on with things.

Darren Jakal · « **Reply #12 on:** November 03, 2016, 02:32:28 PM »

Well Bill I was able to pick them up and get them on for trial.

The guy I bought them from had them mistakenly on a 350 and he bought them off ebay so I'm not sure of what I have.

It took a bit to get them on (I had to spread them out a bit). However, this is the first time I've fit a header to a sohc4 so maybe this is normally a bit of a struggle.

I was a bit worried about getting the oil filter off, but it works.

Are there any marking on these pipes to really know what I have?

cheers, dj

edit to add: I found a stamp of the rear bracket 2047 R

BomberMann650 · « **Reply #13 on:** November 03, 2016, 04:50:53 PM »

The 350/4 block is smaller, are you sure the other guy had the "wrong" pipes?

I'd be double checking the flush factor at the head/flange connection. A wrong angle will be tough to seal even with a fresh copper ring.

Darren Jakal · « **Reply #14 on:** November 03, 2016, 09:17:46 PM »

Yea Mann,

When he told me that I got a bit concerned, but dam they look cool.

Anyway I think he had to squish them a bit to get them on (he said they never fit his bike right and that was because they were for the bigger 550 engine). Once I spread them a bit and wrestled them on they did suck up solidly.

I was wondering about the copper rings. Is it necessary to renew them? Where do you get them?

Thanks again for the help, Darren

Honda has em. They also come in gasket kits too.

They are nice looking pipes.

new ones are required any time the exhaust is removed/replaced.
aftermarket brands are fine.

Cheers Flybox,

I hope to get some from a local dealer up here in Canuckistan. It would be great to have such easy access to all these US parts places and while I know they ship to Canada it is always a bit iffy when it comes to Canadian customs.

I might do a big order one day and have it shipped to the border as I'm often within striking distance of a border town shipping depot.

Thanks again, dj

bill440cars · « **Reply #19 on:** November 04, 2016, 10:59:25 AM »

That is great, that you have them and they do fit. I wasn't much help, other than knowing, in my Own honest opinion, that they look pretty good. Yeah, you are subject tp leaks, if used exhaust gasket rings are used. Those are on ebay quite often as well and not too pricey. I would prefer a nice 4 into 1, but can't usually swing the cost and the Jardine setup is a decent alternative and some folks prefer the "Balance look" of pipes on both sides. Enjoy. Bill

I have a system almost identical, but I'm not sure if it's Jardine or not. I cant' find a manufacturer stamped on them.

But they DO stick out too far, and the fender is caught between the headers under hard braking, especially if you have a passenger or a load of some kind on the bike. or you're heavier than me, I suppose. I have two dimples in my front fender now as a result. I ordered a Hindle 4-2-1 last week to replace these pipes because they are no where near safe. I'm not sure if ours are the same, but definitely check to see if your fender gets caught under full compression.

Darren Jakal · « **Reply #22 on:** November 04, 2016, 11:48:31 AM »

Wow markreimer,

I sure hope this isn't the case with these.

I did find a stamp on the rear bracket that says "2047 R" If you have them off or can see in there (it would be tough with them on the bike) would you look and let me know.

I will look into the interference.

How much do you weigh, btw? Is your front end stock?

Cheers, Bill and Flybox for your help / comments.

Darren

Darren Jakal · « **Reply #23 on:** November 04, 2016, 11:53:32 AM »

Sorry to ask more, but where is the interference? With the inside set of pipes or the outside?

cheers, dj

That's a Good "Heads Up". Better to be safe than sorry, for sure. Mine are on my (Dare I say it), '80 CB750K (DOHC) and fit quite nicely. Hopefully, they fit better on some bikes, than others. Shame the manufacturer's (of your's) didn't catch that. Now, has me and I am sure others, wondering if we are talking about the actual same brand or not. Be worth looking into. Sure can't be too cautious on this. And Darren, you are most welcome. That is just what most of our group does, is to try to offer caution, info and support to others. This is a Great place to be and is proven, because it is still here, while others have gone by the wayside, for one reason or another (and I am not saying that ALL have folded, because of not being a good forum either. I have seen some that seemed good, but sadly, folded for other reasons).

markreimer · « **Reply #25 on:** November 04, 2016, 11:56:22 AM »

I'll take a look when I get home in a few hours. I don't have the original muffler brackets though. Is it stamped anywhere on else? I'll see if I can find anything that helps to identify.

My front end is close to stock - I replaced the original springs with some Progressive springs about 4-5 years ago. Other than that, everything is stock. I weight 150lbs. I don't think I've had the issue while riding alone, but anytime I have a passenger or camping stuff on the back, watch out...

The interference is on the inside of 2/3. The fender literally goes right in between the two middle headers if you're riding in a straight line, preventing the bars from turning until the suspension pushes the wheel back out. If you are already in a turn, the fender just bashes into the header, hence my fender dents

flybox1 · « **Reply #26 on:** November 04, 2016, 12:07:09 PM »

Hey mark, yours dont look like 'em.
A noticeable stamp "JARDINE" on the rear peg mount tab and trumpeted end.

Darren Jakal · « **Reply #27 on:** November 04, 2016, 12:18:37 PM »

Hey thanks to all concerned, I'm actually quite touched by it.

Anyway, here is a pick of the outside pipe with the collar on.

The inside pipes ride pretty tight but maybe the bend is up high and sharp and in the right place for problems.

As Flybox says there are some differences between mine and yours and by my eye it does look like your pipes stick out a bit more.

I will for certain be aware of this when I get the bike together. I hope these work because they do look great.

cheers, Darren

Darren Jakal · « **Reply #28 on:** November 04, 2016, 02:04:13 PM »

Here is a picture of the rear bracket with the stamp 2047 R. Looks different from the other brackets I have seen.

Picture 2 is looking into the exhaust end.

There is no brand name that I can find.

I would love to know what these are as they are cool and the cost me $200 pesos.

cheers, dj

markreimer · « **Reply #29 on:** November 05, 2016, 01:43:46 PM »

Well I tried to find a manufacturer stamp on my system and I couldn't see anything, so seems like we have different ones. Just check for clearance and if it's good, the get out and ride!

Hey thanks Mark,

I'll make sure to check these out for interference when I get it together.

Something to think about with any header I guess.

cheers, dj

Hey Mark, I run what I think is the exact pipes you have in one of my bikes. I don't have any issues with fork clearence (I'm running a gsxr front tho). One issue I should note was with the kickstand. It rubs/bangs on one of the pipes a bit. It's possible that I tucked them in too tight and could've moved them a cm right to avoid this on the install. But it's something to be wary of when you install them. I had mine on a jack not the stand when installing. I really like them tho, bike is pretty quiet and not "buzzy" like my others
