2003 Exhaust piglettes

[Valkrider62]

I just purchased a 2003 Valkyrie and the piglettes have been cut off.  On a stock exhaust how long should the piglettes be?

Tourer/STD on the left, Interstate on the right

You can get the above "piggy plates" here: www.horseapple.com/

Some times people cut off the piggies and then jamb a big drill
down in there and drill out more stuff, you might look down in there
with a light, or feel around with a stick...

Yes, Mike that is what they did.  Cut the piglettes and drilled about a 1/2 inch hole in the rear baffle plate.  So which piglette will be the quietest?  The short or the longer ones?  I have 36 inch stacks but will need to have the baffle and piglettes fixed first before installing them.  Is there any place in Phoenix AZ that does this kind of work?

You might want to check with BigBF. He is a  VRCC  member and very good mechanic.

I like quiet. If you want the quietest, find a set of unmolested Interstate pipes.
A full face helmet and drilled chopped pipes leads to unbearable droning
I think.

You may end up in good shape with piggy plates and plugs or something for
the drill holes, especially if you can get BigBF to help with the work...

There looks like some options to repair the piglettes but what about repairing the holes in the baffle?  Is there a plug that can be installed in each hole or do I need to send it to Horseapple to have both corrected?

Don't know, but I'm sure Mark T has the answer.

You might could try a set of the Rex Stainless Insert Silencers.

Here's a thread.

The holes in the back baffles make it somewhat louder but not a lot.  More of the drone comes from the piggies being cut off.  Honda extended the outlets of the exhausts to the end of the tips to prevent drone inside the cone. You can replace the cut off piggies with the "piggy plates" pictured above - that's my pic of the 2 styles - either type is $20 for the pair plus $12 priority mail. You might want the longer ones (interstate) to move the sound to the back of the stacks if they are 36". Here's how Hedgehog installed the piggy plates w/o welding equipment:  http://www.valkyrieforum.com/bbs/index.php/topic,38448.0.html

You can't install the same baffle plugs that were drilled out because the ID of the piggies is smaller than the inner tubes where the baffles are.  I do repair them if they are drilled out and the back section is going to be used as silencers, as the OEM plugs can be inserted from the inside end and tack welded in place after the silencers have been removed from the cans and "skinned" so you can access the sides of the tubes.  There are holes on the sides of the tubes where weld can hold the baffle plugs in place.  They look like freeze plugs you see on the sides of a cast iron auto engine block.  I have a ton of them on hand from the early days, when I removed the entire baffle assembly intact - now I cut the baffle plugs out of the tubes and re-use them.  So your holes can't be repaired the conventional way unless you cut the back section off - it's 7 3/8" from the end face - just fwd of the rear most spot welds on the sides of the muffler can. Then skin the silencers - I use a lathe - and then the plugs can be welded in. Yes I can do that but if you are going to that trouble of sending me your pipes, I'd suggest having the glasspack mod done to pick up some power - then you can insert the silencers back into the stacks when you want quiet and still have a deep rumbly note and more performance.  And have your custom look too with your stacks.  Send me your stacks (as well as your exhaust) if you already have them and I will do the mods and put it together, and discount the package.

I am not looking for more horse power, just quiet like the stock 1800 goldwing or quieter.  How much does it cost to have the work done to my exhaust?  Did the interstate have a quieter OEM exhaust?  If so were all the 1996-2003 interstates have the quieter exhaust?  This is all new to me so bear with me.

They only made Interstates a few years... 1999-2001 maybe... Interstates have
the longer tips at the end, and longer piggies. I've run all kinds of OEM pipes
on my bike... drilled out with piggies cut, regular unmolested STD/Tourer,
triple-tip unmolested STD/Tourer, and unmolested Interstate pipes. The
Interstate pipes are the quietest. The difference between Interstate pipes
and STD/Tourer pipes isn't all that much, not near as much as the difference
between drilled/chopped pipes and unmolested pipes.

I don't know the engineering behind it, I just know from experience... so I wonder...
what would the effect be if the piggies extended past the end of the tips? What
would the effect be if the tips were stuffed with fiberglass (without blocking the
ends of the piggies of course)...

You could quiet it down by separating the silencers from the mufflers (as I said above), skinning them, replacing the drilled baffles, installing stacks, and inserting the silencers back in the stacks and pinning them there with a screw.  This will give you an exhaust that sounds just like stock if you don't recess the silencers much, yet you can occasionally go loud if you want by removing the silencers (temporarily) just by removing the screw and pulling them out.  I can do this mod for you, but won't conduct business here.  Drop me an email, given at my web site along with my phone.  www.horseapple.com

Thank you I will e-mail you.

If you are just a shade tree mechenic you can fix them yourself. I was unable to find the post where a newish member replaced the cut off pipes with those already mentioned you can buy from  horseapple.com. He had pics and instructions. Basicaly you apply a layer of muffler patch material (found in any parts store) to the flat part of the existing cans .  You will need to predrill three holes in each flat plate on the new pipes and then line them up with the cut off ones and drill pilot holes in the existing muffler plate for the selftaping screws you will use to  fasten them with.This will seal the tips to the can.  As for the drilled out internal baffles I did a similar fix internaly back in 2004 on my then recently aquired 97 model. It has held up to this date. I do ride, not as much as before grandkids but still around 4k a year. Here is how I did that.

If you do both you will be back to stock sound.

I would like to thank everyone for your reply.  It has given me some options and insight on the Valkyrie.  Thank You!
