Topic: IN SEARCH OF THE ULTIMATE 4 into 1 FOR MY SCOOT -> HELP NEEDED......

[puppytrax]

Maybe I am better off having my Chassis shop/racecar builder buddy make me up a custom 4 into 1.
"Custom" = big $$           

Here's a thought...two-into-one *scrambler* pipes...1 1/2" primary pipes from 1&2 and 3&4...feeding a 1 5/8" tucked-in pipe going to a "hot dog" muffler...think of the old CL72/77 Scramblers...   

Personally, I would do a 4 into 4 scrambler pipe setup...dual hotdogs on each side...and the pipes hugging each other...   

But then I'd have to find a pipe bender; 21' lengths of SS 304 tubing; SS mufflers...and bushel baskets full of $$$...

Thanks for all the pics 
After looking at all of them , I really think no matter what 4 into 1
I go with, I am gonna have ground clearance issues with my bike being so low to the ground.
I think for now I am gonna run what I have, and maybe over the winter have a oval piped collector made using my exsisting
header pipes , then into a cannon of some sort. This way I can insure it will maintain the ground clearance I need to be able to ride/enjoy
my CB as I do now..

Pro-Teal - I just got my paws on a Marving Race System for my 550F Cafe project. I've got no pic of it on a bike and won't have one on my bike for some time to come, but from what can be seen in the seller's pic it looks like it's been routed underneath the engine and just swinging outwards in front of the rear wheel.

Cheers,..

I've got a Hindle pipe on mine. Street and Competition used to carry them. It's a very nice 4 to 1 merged collector design, although it only came in nickel plate. The collector is 1 3/4" so almost any modern can will fit as long as it has spring connections. It sounds unbelievable without a can though. Pat Bodden had one on his Big Benly  cb 750 Ahrma bike featured in Cycle World a few years back, before he went to 4 to 4 megas to comply with the rules. Maybe contact Hindle directly, as I'm sure they still have the jigs to make one up.I'll try to post a picture if I can figure it out.

I think I have a winner !!!! 

Tom a.k.a ELCHEAPO has come thru again with a header for my scoot. 
It's alittle rusty , but but some elbow grease and some muriatic acid will get the majority of the surface rust off.
Alittle black BBQ paint and a nice tight hearwrap job and I will be in the show. He said the collector is only about 2 1/2'' thick ,
so ground clearance should be an issue, compared to the mack system which is much thicker under the bike..

Still up in the air about how I am gonna finish the exhaust, weather I do some sort or angled "cannon" , put a newer sportbike muffler, or another idea I have cookin thru this bIg head of mine which I will keep to myself 

Thanks for all the input, and I will post my progress pics and the exhaust project gets up and running....

    Not to get in between you and Cheapo, just want to point out that header is a stock 75-76 750F. You will need to add exhaust studs to your head and use flanges and collars to mount it to your 73 750( providing that your 73 engine has not been modified and still uses the older style exhaust spigots that bolt into the head). You probably already know this since your first post shows a pic of the later style Mac system. I will now return to minding my own $*&% business

I run a Hindle also with a carbon race cannister. I also have a Stealth carbon can. I had mine coated by HPC...it's a great finish. I was talking to Mark McGrew at M3 racing and he said Lang Hindle said he would have to make something like 500 units for it to be worth it for him.

Hey Joe, greetings from Tokyo!  I'm sitting in my hotel room going over the posts in my favorite website!  Can't keep away from the best hobby in the world!  Anyway, just to let you know, I have a Kerker on my other '76 750F, and have to say, the sound from the Kerker with the baffle and end cap removed (which is basically what I have on the yellow bike) is NOT the same.  Sounds kinda sick actually.  Didn't like it at all.  I put just the end cap back on without the fiberglass baffle, and it sounds more like the stock system with a straight through pipe.  So, I'm thinking that it's (on the yellow bike) definately not a Kerker.  I'll be reading these posts on a several-times-a-day schedule even when I'm overseas.  I'll be stuck here on business for a week, and then to Shanghai for 2 weeks.  Damn, I wish I was home riding.

Hey man , no problems here. I appreciate the help/input/etc....
ALL help/comments are appreciated, thus why I posted a pic of it...(the header)
Me and Tom are working something out to get this to fit on my scoot, as I still do have the early style "spigot" style
exhaust collars on my scoot...

I'm thinking that it's (on the yellow bike) definitely not a Kerker.

Hey STEVE, hope you are enjoying your trip...
Thanks for at-least letting me know the system on your yellow bike is not a Kerker, as thats one manf. I can take out of the running.
Like I said , I am gonna need a few good close up pics of the exhaust on the yellow bike, so I can post them up and see if anyone recognizes what kinda system it is.. I really need my bike to sound like yours, as it is just too killer...

[ElCheapo]

I did not get a chance to read this bugger completely, (will in the AM). But guy I have done this mod just the opposite that teal has to do here.

Really not all that hard to do. I did mine in the rain last time.... 

[madbunny]

i'll gladly help you amortize the costs of conversion if you want to let of your early style exhaust spigots go cheap?!
need'em for a '76 automatic into a '75 bobber frame conversion...

[ProTeal55]

I spoke with Tom (ELCHEAPO) this morning , and have decided to continue the search for a header that will bolt right up to my head. Not saying that the conversion is too hard, or I am not able to do it , I just have this gut feeling that it will turn into a fiasco, putting the bike in a non-rideable state, getting me pissed off, making me set the thing on fire, etc...

So , back to looking for a 4 into 1 system that will sound wicked, and give me enough ground clearance to ride without bottoming-out on every bump. I know KERKER is def. out, and the MAC system will need to be chopped up to work, which might be my best bet...

Now if I could just get STEVEF to sell me the system on his scoot...

[madbunny]

well,
there's always whatever-in-the-name-of-spaghetti-this-thing-is.

don't really understand how the thing clears the oil sump though?

I really like the look / idea of this setup. Seems as if I would have to change over to the later style exhaust setup, just like with the header ELCHEAPO was gonna proviede..  Looking over his feedback, their are a few people who don't have the best things to say about his system , plus he doesn't accept paypal which makes me cautious. The last thing I need is to get screwed over some stupid exhaust.

Anyone have heard about this system ?
Good things  -Bad things - Know of someone who is running one  - etc ??

[volthause]

have fun changing your oil filter with that on there.

[madbunny]

discussed on a another board but appearently not resolved.

our very own scondon mentioned having purchsed one last summer, any follow-up scon?

[ProTeal55]

With the exhaust being so small, It wouldn't be bad to remove it to change the oil.
I could live with it...

After reading that , I am no longer intrested in the above pipe. I did find the pipe below on Ebay just now.

The price seems right , should bolt up like the current exhaust does, and I can always cut off the stock muffler and weld a cannon on or something else creative. Looks like the lowest part of the system is thinner than say a collector on a MAC system.
Opinions

I would be curious to hear what he thinks of it....

     I'm planning on using the X-pipe on my current build. I haven't actually run it yet but did mount it to see how it fit and also to get an idea how I'd be changing oil in the future. This is NOT a bolt on system. It comes in 5 pieces covered in crappy uncured BBQ paint job and the collecter needs to be either drilled and bolted or welded on after proper fit has been established. The header pipes are a bit too long so the collecter hangs too low in the rear so I will have to take it to the race shop and have them bent slightly and have a bracket made to mount where the center stand used to be in order to hold the collecter up. It'll be months 'til I get a report on how it actually runs.

     Teal/Cheapo, I didn't at all mean to get in and kill your deal. Just wanted to point out the parts you might need to fit it. Feel pretty crappy 'bout that. I've got an old spigot mount Mac system gathering dust in my garage that I'd be more than happy to part with cheap and split the proceeds with Cheapo. It has a "quiet" exhaust note and not sure whether the baffle can be removed but there is a screw on the end of the muffler. Let me know if youd like pics.

     Also have a spigot mount Kerker covered in glorious '70s rust. Baffle ready to fall out, sounds mean

[ElCheapo]

No need for all that, really... Teal NEEDED to know what he was getting into and you guys let him know. Thanks.... It actually slipped my mind that his was a K2. While these can be done, they can be hard - or they can be dead easy. It all depends on how well the screws come out of the head. Not sure why Honda went to more parts in the later exhausts. The spigot types worked just FINE. Went from three pieces (clamp ,bolt, and nut) to 8 sleeves, 4 collars, 16 nuts and 16 washers WTF??

[ProTeal55]

SCONDON --->
As Tom said , no harm no foul.
No need to apoligize ,its kewl. 
I think I am gonna buy that ebay exhaust, and do alittle "creative" welding to try and get something
that both looks good, and sounds wicked...I am thinking about getting that header, and then welding up this racecar type bullet muffler to it - on a slight angle. The shortest youc an get is 12'' , so I need to d osome mock-up's before I order anything..

Might look kinda trick , and should sound wicked (i would think)...

[Rushoid]

I sure would like to hear some sound clips of different 4-1 setups. It would make decisions a lot easier. Mine sounds ok I guess but I have nothing to compare it to. It might sound killer, or weak as hell. I don't know what brand it is (no name found on it) and I haven't seen any others that look like it. I think the headers might be stock. One thing I do know is that I like the way it's bolted on better than the kerker setup. I'll try to post pics later.

[scondon]

  All right then I'll breathe a sigh of relief, thanks guys. Teal, my buddy has one of those exhausts your looking at mounted to his '76 750F. I'll see if I can get a quick pic so you can see how it hangs. If memory serves, it is a straight shot back from the collector so any angle you want to add would have to be done to the "muffler" portion.

[ProTeal55]

Teal, my buddy has one of those exhausts your looking at mounted to his '76 750F.

76 huh ?
It says in ebay description that is is for early K models ? So this exhaust (pictured below) will not bolt right up to my bike ?? I thought it would be clutch becasue the collector doesnt seem to hang nearly s low as most other 4 into 1's I have seen...

Here's a link to the auction --->

i don't think you'd be able to properly mic some of the unbaffled 4 into 1 setups.
it's the kinda bass that just causes heart palpitations, you don't really hear it.

[dusterdude]

joe,it should,it appears to be for a spigot exhaust
