C-14 Dual Exhaust
« on: September 03, 2011, 09:07:41 pm »
So I've seen a few C-14's that have a dual exhaust system installed...this is something I would like to investigate as I think it looks way hotter then our Howitzer now ;)

What are the advantages (aside from looks) and disadvantages,  who makes it? do i need to remap the ECU for it etc etc :)

Thanks in advance
You only need two tools in life – WD-40 and duct tape. If it doesn’t move and should, use the WD-40. If it shouldn’t move and does, use the duct tape.

Hey Marc,
I just got the Muzzys dual carbon fiber full exhaust the other month and love it!  :great:

Yes, you'll need to either remap the ECU or get a PCV. You'll also need to get a modified center stand, also available from Muzzys.

A big advantage is the power gain, I gained 14 hp over my previous slip-on with stock header set-up.  :motonoises:

Here's some pics of mine...

Mine has a ZX-14 header with Two Bro's Racing slip on silencers.  It looks good to me...  ;)   I think it's too loud, but many say it is not.

The ZX-14 exhaust bolts on with no remapping needed.  You do have to address 3 issues though, the side stand clearance to the left mid pipe when up, the center stand step pad hitting the bottom of the left mid pipe, and what to do for a left muffler mount.  There are many solutions for those issues though.

I actually saw a real ZX-14 for the first time this weekend (been looking for one for over a year).  Those stock mufflers are really long!  They must be as long as the stock potato launcher!  I was very surprised.   :o

Like ZG, I have the full tilt Muzzy on my 2010 Connie.  I love mine as well.  With the Dynotronics ECU re-Flash and the full Muzzy exhaust ... I gained 20 ponies over stock and 10 ft/lb torque.

Sounds awesome, too .... and looks terrific.

Wow, that is exactly what I wanted... Just wish I could find a "Quieter" exhaust and still accomplish the same thing (I like the look of the muzzy's but the sound during a LONG highway blast just drone and drones on..)

I went with the full ZX14 dual exhaust-  $150.00 on E-Bay and not a mark on it. Did it for the cosmetics.

The side stand and center stand are very easy to fix.









Have 11K on the bike now- no remap required- sounds different than the stock C14 exhaaust, but is still very quiet.


Thanks  Tom

Hey ZG- loving the black rims.  Very nice.  I was surprised the Muzzy duals added that much more hp over a slip-on.  I think that's om par with the Area P full system, and I like the dual outlets.  Isn't it funny when I had my C10 I always wanted a nice 4-1 exhaust and now with the C14 I'm liking the looks of a dual system 8)

Watch e-bay all the time. There is a lot of junk being sold. I started looking for this exhaust even before I had the bike. It took a couple months to find it. The guy posted it and within an hour I made him the offer (less than what he asked). I wanted a complete system off the same bike, just so there would not be any parts mismatch.

They are out there, you just got to look for them.


Thanks  Tom

The center-stand has to be modified or it will hit the left exhaust, some folks just opt to not have a center-stand anymore but I got the Muzzys one...

On mine, I extended the part that you step on so it comes out around the mid pipe.  I have one more mod I need to do to mine, but it works now.  The longer lever also makes it easier to hoist up on the center stand with the bike fully loaded.

For the side stand, you could go with the ZX-14 side stand and mount, or shim yours away from the engine with a spacer, and use longer bolts.  If you don't want to screw with it, I would recommend just getting the ZX-14 side stand.

The third item you need to address is the left side muffler mount.  Muzzy makes a modified one you can just buy, or you can have a mount welded onto yours, then have it re-powder coated.

I didn't have to mod my side stand Rob.  :017:

I've not heard of the side stand needing to be modified. Only the center stand with dual exhaust. IIRC, muzzy even sells a modified center stand. I think there is a core involved though.

The side stand will hit the left midpipe lightly.  I just heated the sidestand and re-bent it to follow the curve of the pipe.  The bike does lean over a little further. Originally, I was going to lenghten the sidestand, but it hasn't caused any issues so far.





The center stand requires a 3" extension on the foot lever to get it outside the midpipe. It does make it much easier to use the center stand.





Hope this helps.

Thanks  Tom

and the headers just bolted up?  How did you hang the left side Muffler? :)

I used a piece of aluminum tubing and welded it to the left bag support, duplicating the mount on the right side.



I used a system off of a 2008 ZX-14. The header is an easy bolt up. The mid support does not line up so I left that out and used the rubber cushon in the left muffler hanger (same as the rear right rubber)

I've noticed a ZX14 OEM exhaust set listed locally. Damn you for making me think about it!

Not keen on modifying the stands in case I want to restore it to original in case I don't like it, but I guess its not the end of the world.

Edit: Does anyone know which years of ZX14 fit? The one I saw for sale is a 2007
