best way to saving weight in our FJ is to change the original
exhaust system. But take
account of that the OE
silencers act like a counterweight to damped the engine
vibrations, similar to other sport-tourers like the CBR
1000 XX or my own CBX 750.
To me it is a
near security necessity to
fit a louder exhaust.
And I notice each time that I ride my not too loud FJ compared
with my outrageous-sound CBX: the sensation is to be invisible to
the rest of the traffic. That old lady who is going to cross the
road with her old Volvo is not going to see you unless she can
hear you. In EEUU concluded that sound saved lives. I am not
praising about to be an uncivilized motorist. We can ride around
2.000 rpm at 2 in the morning
in our FJ with a louder exhaust without to disturb your
The OE double wall headers of my 1100 starting to crack, so an
intrusive ticking noise surging from them did that I started to
look around for a complete system. This problem was eliminated
by Yamaha fitting single wall headers from the first 1200 mode
Cheap and good replacement for the cans if you like the
original sound. Excellent quality and finish.
And they are better looking (I think).
Mingo bought one Motad complete system from Motad and my
friend JC a collector box. Motad claims that fitting is
excellent and gaskets are not needed. Well, It´s wrong.
there are a lot of air leaks at the joints. After spent a ton of
exhaust sealant paste, Mingo fixed it welding the different
parts, but think that with a little damage he will need to
change the complete system. NOT RECOMMENDED AT ALL
the complete system
My friend Jose Carlos FJ fits a couple of these. With a little
polish they don´t look so horrible. The best of them is the
excellent results in sound and power. And when riding you can't
see them. Recommended!.
4 into 1 system, fitted in my FJ 1100.
It was a titanium item that weighted only 3,5 kg. Think that the
weights around 30 kg. The sound was near savage and
outrageous!!!. The only problems were no access at the oil drain screw
and centre stand lost.
think it is discontinued
Laser K2 4/1 race system

it: bad fitting causes a lot of

Cobra F1R race silencers
Very cheap system and
good quality, although not at the level of i.e. Micron or
Yoshimura or Muzzy. Ooutrageous
A pair of them weight less than 1 only original muffler.
Models!. It is too obvious that simply taking the silencers
out of the parcel I thought that the shop was wrong with my
order. I checked them carefully and the silencer
around 10 cm too short to fit them properly, because in FJ 1100
and 1200 pre 88 the silencer fitting points are in front of the
rear footpegs, not below them like in post 88 models. So I changed the
rear fitting point with an invention from myself, involving 2
simple long screws, 4 shims and a pair of lock nuts. I think it
is a good solution, because now the OE rear mounting point only
supports the rear carrier fitting kit, and not both the exhaust
& the carrier.
my friend Edu´s FJ vs. my friend Mingo's FJ, both of them same
model (1986 1TX), with similar mileage, OE carb settings and
with KN, It is clear that the power lives on the exhaust: Edu´s
FJ, with these hand-made free cans feels stronger along all the
rpm band than the Neta fitted Mingo´s FJ. Edu´s FJ seems other
motorbike, with more punchier,
and more power motor. So I ordered a pair of them.
And even I´m
not a friend the home made inventions, these cans are perfectly
made, excellent polished, fit exactly and my FJ feels stronger
with the more free cans, even although these are not so loud
than the F1s.
collectors are made from steel, so using a lot of decapant, an
electrill drill and a lot of your time, you can eliminated all
that black paint that usually start to drop every 2 years. For
more dedicated owners, you could even polished the collector to
give them like a mirror finish. After 5 days fighting with my collectors,
I decided that there was enough, leave them alone and applied a
thin of transparent anti-caloric paint to avoid rust. The final
result is fantastic
Open collector box/XJR
OE FJ collector box
weight a lot so it doesn't seem a bad idea to change it. I
bought a Special made collectors & box to fit the XJR 1300. even
although it fits, I can't recommended it because the system
don't fit so exactly than the OE system.
changed the box only with one made to fit FJ 1200 models,
lightly different from the XJR models. It is completely open and
it sounds like a FW190 from the WW II because the box doesn't
break the sound impulses waves from the collectors. It sounds
like a super Ducati, but with enormous low down power.
alternative to replace the OE items, when the mod to convert
from 42 mm. To
fit them on 3CV models (88-90) you must make an adaptor similar
to those made to fit the F1 silencers or cut and re-weld the
original supports. Now, on March 2.015, I've fitted a couple of
them after the Gemnini disaster (read below). The sound is bass
and deep and bass with the inner restriction removed.
And in 2.007 I´ve fitted
this cans too to my 1TX, but completely open and with no the 42
mm. restriction. I like the sound of these a lot. Much better
with the OE exhaust pan.
that are more restrictive than the XJR ones with the mod done,
but that there are designed to fit straight on. Confirming one
more time that the power comes with sound, the bike has lost
part of the top end.
to mu bike because I liked the aesthetic, and in order to
derestricted them I drilled a couple of holes by inside, out of
the sight. Well, no way. Too much silenced, so they have to go.
cheap cans that I bought from eBay looking for an alternative to
the Schnappon ones. Made of aluminium, very light and don't looks
durable, but the sound is gorgeous and similar to a bit silenced
Cobra F1R (Cobra own F1S, I suppose). Even these were new, the
parts were NOS and there were no ancillary to fix it to my bike,
so I bought a couple of exhaust clamps and with a bit of
fiddling the result is superb, better than the procedure that I
chose for the F1Rs. There is today a Gemini named company that
made exhaust at the US, but only for cars, so these cans are a
rarity, I suppose.
nightmare happened in my annual holyday riding travel: the left
can broke after a 10.000 rpm. acceleration in the middle of
nowhere. We performed an odd job repairing the can and run 200
kms. until Andorra la Vella, virtually exhaust-free (the botched
job only remained around 10 kms.) where we found an aluminium
soldier who made a good job to remain another 2.000 kms.
moment we think that our travel go sunken... but nope with an FJ,
clearly. Always carry enough tape and tie-zips and you could
repair near every problem in a FJ. What a bike!
Cobra F1S Cans
Extremely rare in Spain. In
fact, the only pair that I've seen fitted in any bike in all my
life. My Groundhog Team friends, JC and Miguel, have a customer
with a couple of these fitted in his FJ 1200 3cv. So JC fitted
to his bike and tested it. The cans are old and not too lusty,
but the effect is wonderful: with a deep bass sound, the cans
reinforce the middle power and the FJ feels more powerful. The
sound is not so louder like the F1Rs.
you can find a pair)
