Any Honda Dominator NX650 owners out there ?

[Honda Scoot]

I was also looking for dual headers for a 1988.

Service Honda shows the left, Pipe B (18321-MY2-620) as discontinued. Perhaps some around else where?

New headers with a Jet Hot Ceramic Coatings "Extreme 1300 Polished" would be nice.

What ia a single muffler alternative to the stock duals? Where? Apparently no one wants to buy my '88 so I guess I'll do some modding.

Best case with all the induction, carb, internal header welds (if there are any), and muffler can mods would probably still be in the single digit percentage of increase.
And definitely more $ than a 14 tooth front sprocket for the same percentage of acceleration increase.

I didn't think $750 was very expensive for exhaust; top of the line exhaust for CBR's is usually around $12 or $1500. My only concern with buying an exhaust for the NX is if it is cost effective.

I payed $467 U.S. dolllars for a complete headers back exhaust system on my XRL...FMF powerbomb SS header and Big Gun Evo R aluminum Silencer. $750 U.S. plus shipping does seem pretty expensive for a set of steel slip-ons. You'll get a noticeable seat of the pants power gain, but I'm not sure it'll be worth $750. The look might be worth it to you tho I payed $709 shipped for my full SS Yoshi on my busa.
Unfortunately Dommies parts are high cost...thats the only reason I passed up on a beauty of an 88
Personally I would still shop around more, or maybe even consider switching over to a full header-back single system off an XRL or similiar...it wouldn't be duals, but it would cut alot of weight up high, give a big power gain, still look very cool, and be way cheaper I'd think. Not sure its worth putting $750 worth of steel slip-ons on the Dommie financially.

You could also internally open up the stockers for equal flow to free-flowing slip-ons, then get them powdercoated any color you wanted, that would be a very cheap alternative to expensive slip-ons, and you'd still get the power gain and good looks
Some of the XRL guys are doing that with their stock systems, and getting good performance results and sharp looks

OTR in Germany sell stainless oversize headers for the NX650 for 160 euro.

Imo they are not worth the money. They look nice, but that’s the only good thing about them. They are designed to meet European Laws, which means the sound sucks and the power output is rather lesser than more. The best (roadlegal) exhaust in terms of sound and power is still the original one.

But if you don´t care if your Dommie becomes much noisier the Arrow Paris-Dakar may be a choice. It’s made of stainless steel, it is light and inexpensive. And with some carb/air filter mods you may even get a decent plus in power

I believe the headers from the XR650L will work for a 2 into 1 setup.

They will be close but not an exact fit.
You may need to do some pipefitting!

i fitted XR600 headers and universal supertrapp quiet series silencer.totall cost 30euros for headers,20euros for midpipe(used) and 80 euros for new silencer.headers are quiet easy to install in RD08 frame.
carb rejetted in dynometer and works fine.
the only reason i changed stock exhaust is weight loss and not the power.

stock headers(kilos)


XR600 headers+mid pipe



left and right stock exhausts





Supertrapp silencer


totall weight loss 5,3 kilos from the tail of Domi,not bad at all

[Dominatoras]

i used new exhaust gaskets



oil drain bolt is opening without problem



i made a bracket to hold mid pipe in left hole using the stock rubber and bigger bolt(photo is with stock headers)


and silencer fitted without problem with Supertrapp bracket

I have a rebuild going on, i am planning to use XR only headers CRF250 cans and 42mm mikuni carb, going to try to bolt up a CRF 450 swingarm, will the crf shock work?

[dstriffler]

I didn't realize the stock cans weighed so much! I'd be interested to know more about the CRF250 cans. I know the 2013 CRF450 has dual cans, maybe there's possibility there?

[dstriffler]

Maybe not. The cans themselves might work, but the pipes connecting the can to the header look too short.

Yeah, i think this would take a little work but i like to try different things

I recently bought a set of European handguards for the NX. My problem is that the bolts through the front brake lever and the clutch lever aren't long enough to support handguards. I could order the European bolts from cmsnl.com, but it would be $52 with shipping. Is there a better solution for this? The bolt is not a standard type, so I don't think my local hardware stores would have anything like it. Would a standard threaded bolt work? Here's a picture of what I need:
