New Pipes

[Gobux]

Can anybody recommend pipes for my 1999 Honda Valkyrie GL1500CT. I have just recently purchased it and the previous owner installed cobra pipes and then removed the baffles. Sounds horrible. I would like to put something on close to the stock sound. I have searched for a used set of pipes but no luck.

[Kaahn]

definitely want to check out Mark T

They are pricey, but the best if you want that stock performance and nice throaty sound

I went through the same thing when I got my valkyrie... it didn't
have cobras on there, it had drilled out OEMs that were rusty.
For a while I ran some pretty good Interstate pipes on my bike,
until I finally found a real nice set of Tourer pipes. There's
a small dent in at least one of the headers on the Interstate
pipes, but I still have them...

Ebay and craigslist occasionally have nice pipes, and the Pinwall
ebay reseller often has lots of stuff - he knows what it is worth,
though...

where are u located? might be somebody close to you that has a set but doesn't want to go through the trouble of shipping.  Like me, I have a set of Thrush glass pack pipes for sale and I have no idea how to ship them.

I live in Jacksonville Florida. Trying to locate a swap meet for Honda during Bike Week

Yea......I have been lately contemplating the opposite!!!

I was thinking of making the sound, as it should be.

Like a Ferrari race car!!  

To each His/Her own I guess?  BUT!!!   The sound of the pipes, ARE all in the "tuning".

If your bike is tuned shitty to begin with......YES.......straight pipes will only exaggerate that aspect of the bike........

I am no longer an Interstate rider anymore......it is just a "show toy" now.......so loud pipes I could live with.

I am still having trouble finding stock pipes. What aftermarket pipes have you guys used on your Valk. Post some pics. I am going to buy new exhaust I just don't know whats out there

Face book valkyrie pages have them listed.

new cobras,  new oem https://www.ebay.com/itm/Motorcycle-Exhaust-Factory-Sealed-Honda-Valkyrie-Headers-Shields-Tips/264341942975?hash=item3d8c01f2bf:g:qbEAAOSwaLNc7p89

new valkyrie Delkevic exhaust see ebay

plenty of used  ebay.

Viking exhaust only used if you can find them are the best to have.

Vikings, they say, increase horsepower a little, but are not quiet and are very hard to find.

MarkT's reworked OEM pipes, they say, increase horsepower and versions of them are
not too loud, they say, and they are readily available.

Since the OP mentioned "too loud" in his post, I'll say from my own experience that
Interstate pipes are the quietest OEM pipes (longest piggies and narrow echo-chamber
tips).

I have Mark T from Horse Apple Ranch currently building me a set. Spoke to him last night and he's  currently working on them so hopefully I get them later this month. I've heard really good things about his pipes so really looking forward to installing them on the bike.

I have a set of Interstate pipes I’d sell you. But, it’s a long ways to ride here from Florida, and it would be too much trouble to ship them.

I have Vikings, 15HP per dynos viking did, 20HP increase with the air box and jetting I did, I dyno'd with them.   They are only loud when on the throttle hard, cruising nice sound. can be re-wrapped to reduce sound levels even more, which I did.

Still searching for exhaust. I keep seeing slipons. Did the original headers have slipon capability? My cobras do not.

Many memebers in Florida. (And I am sure many sets are around)
Your best bet is find a set of nice used exhaust.

[Gobux]

Thanks

I found a used set of stock pipes in Texas

Be here in a few days

Once installed I will giving away my cobra exhaust if any body wants them. No Baffles

It'd be good to start taking your cobras off... find out now if you break any header studs or need any
expen$ive header nuts... and get six header gaskets. The OEM ones are hollow copper
rings that mash down flat, you might not see the old ones up in there unless you look,
might have to pick them out...

+1 I had to get a pick and fish out 4 of the 6 on mine.

i have 2 sets of very nice unmolested stock pipes, i will trade 1 set for your cobras if they are in very good shape. we each pay shipping.

[Gobux]

My new pipes have arrived and I have already promised them to someone else

[rockbobmel]

You might want to hang on to them for a little bit to see how you like them.  I bought a set of stock pipes and they were too tame for my liking. I ended up putting the truck stacks back on. Plus, If you want to modify the new ones, you have backups if you need to send them out.

[Gobux]

Thanks for all the advise. I did start the removal of the right side. I did find one Header Bolt broke off.
Everything else looks good. Does any body know the part number for the Header Bolt?

Thank you very much.

How to you get the O-ring's out of the manifold?

[Jess from VA]

Thank you very much.

How to you get the O-ring's out of the manifold?

If you mean the (crushed) exhaust gaskets, take a small flatnose screwdriver or punch or icepick and pry them out (carefully to the ports).  If any are stubborn, get an edge out and use needlenose to pull it out.  Then a little cleaning (not the old gaskets).

And get new ones.  There is an opinion on here what kind (of several) works better, but I don't know it.  I think they like OE hollow copper ones mentioned above, over fat fibrous ones, so it is easier to get the pipes on and torqued to spec.

And by torque, they are only supposed to get 7 ft lbs each, or you will snap studs.  Seven pounds is like a bit more than snugging up.  

And you have to run the bike hot (go for a ride or two), and then carefully torque them again.  Maybe three times before correct.  Lest you end up with exhaust leaks later, or the spendy acorn nuts fall off.

Two of my exhaust studs are held on with small double hex nuts, sistered up.  (the most hidden ones)

[Gobux]

Thanks,

I already have the new gaskets (OE Hollow Copper) and I also purchased new acorns.

The only problem I found was one of the header studs has a tip broke off.  trying to get it out is proving to be challenging.

Thanks Again you Guys are Great!!!

[Jess from VA]

If there is enough stud, spin on two nuts, lock them down together, then wrench it out.

Many times, a careful tug tighter, before pulling looser can be helpful.  And a little tapping.    

Penetrating solvent, heat, but not at the same time (without a fire extinguisher).  

(And a decent small extinguisher mounted where you keep your bike is always a good idea anyway.)

I have changed my pipes multiple times and have never changed the exhaust gaskets. I have a set of new Honda exhaust gaskets from the first time I was going to change the exhaust system but when my original gaskets didn’t want to come out, I just left them in the heads. Haven’t had an exhaust leak yet. Just for your info in case you have stubborn gaskets.

I installed stainless split washers on the exhaust studs under the nut. Torqued them down once, and they’ve never backed off.

.The double nut didn't work for me because there was not enough meat left. I found a single extractor for my Shadow a while back.  Get some BP blaster and soak it first. https://www.toolsid.com/bikemaster/6-mm-12-mm-roller-type-stud-extractor-set-mpn-151648.html

Funny how about ten years ago more than a few  posts on this site were guys wanting to make their bikes louder, I recall suggesting that rather than destroying their stock pipes buy some previously molested pipes and save the stock ones.  Personally I like the sound of the stock pipes, but thats my opinion. Looks like the chicken has come home to roost. 

[MarkT]

OEM pipes can be made a LITTLE louder - or a lot, or not really louder at all but with a rumbly timbre, with my sound-adjusting options.  All with more power and a custom look.  I run the pipes on my '97 Jade road bike with Silencers, Organ Pipes and SS wool in between them.  Rumbly and a little louder than stock, and more power.  I have audio which I want to hear so don't need extra loud exhaust.  Not the prettiest picture, on the lift; I just shot this for a buyer to show a closeup of this install.  

[Gobux]

Stock Pipes are installed and I am very pleased. Thanks for all of the advice and assistance.

[twisted]

I have a set of pipes that are like brand new... I bought them years ago from a guy that put cobras on his interstate so the end pipe is horizontal not vertical... I mean these are extreme low miles...  Only problem Im in British Columbia so not sure of the shipping... great pipes though

Cheers

Whoops ... should have scrolled all the way to the bottom!!!
