Valkyrie interstate exhaust

[hvacjack]

What is "Ragnar cut Exhaust". I hve and interstate that is silent I would like a low rumble but not a lot of volume at highway speeds.

[Joe Hummer]

I would start with cutting the piggies and maybe poking the baffles. 

my piggies are cut, don't know about the baffles punched...I don't think so but will have to look into it...here is what it sounds like...

Do one step at a time! Cut the piggies and ride for several hundred miles. Not much difference
in the sound (imho). Then, drill the rear baffle plate. I used a 1/2 bit on mine and that's as
far as I'm going for now. You might want to try a 1/4 bit first. Sounds definately more "rumbly"
especially at low to mid rpms. On my first Valk, I also drilled the front baffle plate 1/2 inch. This,
to me, is the best sound combo. Got a good rumble but not too loud. My wife thought it was
a little TOO much sound for her, especially on a longer ride. I've heard the Ragnar cut on a
Valk but it's been a while. Little too much for me. Just don't get in a hurry. Once you drill/cut
it's hard to undo unless you're real handy at that kind of stuff.

P.S. Just a guess, but I'd say the Valk in the video at least has the rear baffles drilled. Maybe
even more than that.

i wouldnt cut up good exhaust buy someones here that already cut them up..

I will have to look at the pipes and let you know.  Oh...I do have slash cut tips on her...nothing like a 4" resonator chamber.

That might be the difference! I have I/S tips on my STD and it do make more sound.
Also, I've never ridden an I/S so I don't know how much sound is reflected back at
the rider (or camera). 

[Joe Hummer]

My baffles are in tact.  No holes. 

[AussieValk]

piggies cut right back and 4" truckstacks make a sweet sound, much like the video above. I know people say to leave a little of the piggie in-case you want to put it back on but hey, if it needs to go back on I'll just weld it.

[Sodbuster]

Piggies cut and 3/8" holes .... sounds just like the video.  Think I'll save that video to watch mid-winter. Damn I love the sound of that Flat-6   

[Farther]

Mine sounds similiar to the vidio too and I have just the piggies removed.  I figure that the increase sound from the piggy cut is .2-.3 dBA (not much) and maybe an octave lower.  I also have the optional Hondaline three hole exhaust tips.

I would agree .... but I went ahead and drilled mine right off the bat with 3/8" drill and think it's just right.  Just enough growl to hear the motor to judge the RPM's without looking at the tach and quiet enough for touring.

I would also like to know what the Ragner Cut Exhaust involves.  I have a 98 Standard and have cut the piggies and drilled the rear baffles and it certainly doesn't sound anything like Joe Valks IS, much quieter.  I would like a little more rumble and maybe a little deeper sound, so I guess I need to drill the front baffles next. 

A second question is does changing the exhaust tips add to the sound?  I thought that would only change the looks, not the sound?  I love my Valk and always start to chuckle when on a poker run or something and they Harley guys want to start playing Ricky Racer.  My big old Dragon just eats them up.

I think it depends on which tips you get. I put I/S tips on my 98 and does make a
difference. They're a little bit longer and gives the sound more time to "ripen"
before it comes out. Like mentioned above, it's a "resonating chamber".

I agree, one step at a time. The main purpose the piggies are cut is to drill the baffles. The piggies are bent and they don't make curved drill bits, not that I know of anyway. Cutting the piggies will change the tone of the sound though and like was mentioned there will be more resonating happening as the exhaust gases are not exiting at the end anymore. Some of the guys refer to a characteristic of the sound result as helmet drone.  Originally I drilled my rear baffles and put the stock tips on which are flattened, this was louder with lots of helmet drone. Put on Cobra slash tips and that took care of about 80% of the drone and brought back the nice crisp sound of the stock pipe, just louder. Next step will be truck stacks modified so I don't have to cut a big slot in them to mount them. Then I can use 'em with a glass pack set up if I want to hack up my stock exhaust further. Might be nice to have a stock pipe handy in reserve in case a person  wants to switch back for some reason. Some like 'em loud some don't, to each his/her own.

The Ragnar cut is a removal of the rear baffles all together by drilling small holes around each of the piggies and then cutting around them and pulling out the baffles leaving large holes. Have not heard the result but I imagine it would be quite loud.

I run the Ragnar cut on one of my bikes. To me it's the best mod and delivers good sound. You can do the mod with the pipes still on the bike. What is involved to do this is cut the piggies close to the end plate. Go and buy some 3/4" wood dial stock. You will need this for the drill bit on the hole saw. Buy a 1 1/2" metal hole saw. Drive some wood stock in the opening of the piggies and cut it off flush. Center the drill bit in the 3/4 inch wood stock and then drill the end piece. You will end up with 3 holes on each side. Now be careful when the hole saw starts to cut threw. The drill will bit and twist your wrist. Don't ask me how I know this. After drill threw you will need to take some pliers or vice grips and start twisting the baffle until they break aloose. Do this on both sides and that is what is called the Ragnar cut. Also leave a little if the piggies maybe 1/2 inch to give you something to grab hold too remove the baffles. I have the link saved at the house, but I'm out in the GOM and will not be home till the 13th. If you need more details I might can find the link.

Also look in shop talk and click on exhaust 101 and some pictures that will make you understand better.

OK, here we go.....................

As there are less and less low mileage OE Valkyrie exhaust pipes out there, I would be very careful in deciding to do the Ragnar cut. First if you drill out the rear baffles and cut the piggies, you have pretty much destroyed the baffles which could have been used as “Silencers”. Second if you continue to drill out the forward baffles, there is no turning back and you must re-jet the carbs.

I would think long and hard about doing the Ragnar cut. If you know someone who has done it, swab bikes and go for a 100 mile ride as putting around town and riding for any distance may help make up your mind. I would suggest that you go with the Glasspack mod, doing it yourself or purchasing a set through someone such as Mark Tobias
http://www.horseapple.com/Valkyrie/Valk_Products/M2W_Exhaust__System/m2w_exhaust__system.html

who has been doing them for years and unlike the Ragnar cut, glasspacks actually boost your HP.

If you decide that you want to anyhow, then go here for the Ragnar Cut phase I process http://www.valkyrieriders.com/shoptalk/Pipes101.htm and then to phase II

Horseapple ranch is about a two day ride for me, but I think it might be worth taking next Spring.  I really like what he's doing, but would rather go and see what's available and work out any possible glitches on the spot, rather than sending for something that may not be exactly what I want.  And from Northern California it looks like a great ride to Colorado.

I bought a spare exhaust about a year ago.  Took all the trim off and cut it in half with a sawzall.  As a test, I put some 4" stove pipe on.  It sounds much better than my last bikes glasspack, but has a killer drone and really is too loud for anything but local rides.  BUT the idea of cutting it in half is to take the back baffle, peel it and make a removable silencer to use once I get truck stacks on these extra pipes.  I'm really looking forward to see how it sounds with the final mods.  If the silencer really quiets it down, I may be tempted to also drill the front baffles!!  Too many projects right now to finish soon.
