Topic: Identify Pipe?

[736cc]

No clues stamped anywhere. Sounds really sharp w/o excessive noise. Tucks in very tight. Amazing chrome.
I'm guessing RC?

First guess would be a jardine.

[Garage_guy_chris]

I have a Jardine it looks very similar but i noticed a few differences
- The rear tab on the muffler lines up with the rear peg mount
- The rear tab on the muffler is stamped "Jardine"
- The joint from the header to the muffler is further forward under the engine

As far as i know all RC pipes were badged or had a sticker on the rear of the pipe..  The header looks different to the RC pipes i my catalog...

[gecko672]

That looks very similar to an exhaust I had but could not identify. the end of mine had more holes but Im sure they were drilled by a previous owner.

Chrome MAC with a different megaphone?  Doesn't look like an RC collector to me.

[736cc]

My "mystery pipe" is NOT a Mac; different firing collector sequence.

MAC: 1-3-4-2
Mine: 1-2-3-4

[736cc]

Anybody recognize it?

[754]

Is there more thanone type of MAC ? I got a new pipe looks like that and I thought it was a MAC.

[andrewk]

It's gotta be a MAC.  Not sure what you're thinking on the collector firing order, but this is the same pipe-  Pic is from Dime City, the promo pic selling the chrome MAC pipe.



Came across the pic today, thought you might find it helpful.  I think MAC pipes sound pretty good if you use a different muffler than that fart can they come with

[Retro Rocket]

Its easy to see that is a diferent pipe Andrew, different stepped tail pipe and different header shape...

[andrewk]

Huh??

The pictures are different angles, but that is the same header.   First pic in the thread and my pic have the same collector firing order, and the outside pipe tucks the same.  Collector is the same shape, and it even has the kick in the end of it (hard to see due to the angle)

Tell me what I'm missing?

EDIT, I figured it out.  You're right that it's not the same pipe, but it's still a MAC.  The one I first linked is the 001-1301, but what 736 has is a chrome 201-1301.

[andrewk]

Further evidence that it's the MAC 201-1301.

And, for reference, 736's original picture-



Aside from the difference in finish, and the obvious change of the muffler, I don't see how the pipes are any different structurally.  If the exhaust flange is the same (those collars can be added from MAC) that would be the nail in the coffin.

[754]

The big bulge in the muffler, is further back on black one . The chrome one I have is same as 736 has..
.but they look made by same mfg.

[cb650]

The old macs used to have the tapered muffler instead of the bulge.   I have one I bought in the late 80's

[Retro Rocket]

Huh??

The pictures are different angles, but that is the same header.

Sorry Andrew but i still disagree, the 3rd pipe  {second from the left looking from the front.}on 736's pipe is almost dead straight through to the collector, on your pics you can see the bend going back into the collector and the section behind the collector is longer on your pic the muffler is different also, doesn't look like a Mac baffle on 736's pipe either, there are lots of differences.......different pipes mate....

[andrewk]

I already said the baffle had been changed, that much is obvious.  What shape the muffler is has no bearing on who made the pipe, which is what we're trying to figure out.  Mufflers can be changed, the ends of collectors can be cut to fit, etc.

I'm not sure what you're seeing on the 3rd pipe, RR.  The 3rd pipe on the black header has the same angles and points of intersection as 736's and, the bend in the collector is the same-  If you look at the shot 736 provides of the can looking forward, you can see that the 3rd pipe isn't as straight as it looks in the first picture.  The bend in the "mid-pipe" is in the same spot, but it looks like either the baffle is eating a lot of the pipe (possible) or it's been trimmed (also possible).

I don't think any of the pics I've been able to find show the 201-1301 mounted in it's real position.  The additional pics of the black one don't show it mounted or positioned in the correct plane.

But, the bigger question here is that if you're convinced it's not a MAC, then what is it?  There's no other pipe that I've seen that comes close to looking like what 736 has.   It's not an RC, it's not Jardine, it's not a Kerker, it's not V&H, not motard, etc, etc.

It's my belief that the difference in the angle of the pictures is what is leading you to your conclusion, but I'm all ears for some definitive proof.  

[Retro Rocket]

I agree, the same type of positioning of the headers would be a lot better, i'm seeing a bit of a bend {to the right} in the header you showed where it tucks under the number 4 pipe, on 736's pic, which is ain a better position , it looks it goes in almost a straight arc back to the collector, the length of the pipe on the headers after the collector and its diameter, the MAC looks like a smaller diameter pipe after the collector, but it would help a lot more if we had better pics or matching pics of both headers...  wow, does any of that make sense....

[andrewk]

Makes sense now.   Written word is hard sometimes, "It goes THIS way!"

You know, i love to have a chat and can explain things really well, i have always been a problem solver, trying to get all that on paper eludes me, i never was a letter writer....
