Droning is gone!

[Chillerman]

In preparation for some long trips this summer I switched to my stock pipes to reduce noise and allow me to use my bluetooth headset without blowing out my ears. The only problem is I can't stand the stock look! I decided on a set of Grumpys tips and stack extensions. Unfortunately AirFlo was out of the 18" extensions until June but had 38 and 40" stacks available. So thanks to the advice of a couple of members, I purchased a 40" stack (it was cheaper) and cut it in half. So now I have 2 20" extensions with Grumpys tips  . All good, or so I thought. The sound was terrific but the droning at highway speeds was unbearable and the whole idea was to be able to use my bluetooth headset in the first place! So after doing some research and looking online, I came up with these 4" slip in silencers.



I figured they couldn't possibly restrict the stock exhaust more than the 3 3/4" piggies already do  . Here is the installation.



So now I am very happy with the outcome. The sound is still very nice, better than stock, but the droning is gone  . I took a short trip up the mountain to test them out and stopped at an old gold mine. I am undecided on whether the 20" extensions are too long or not . I can always cut them down to 18".

i always cut my stacks to where they were about 1 inch past the rear saddle bag rail...

[MacDragon]

I think they look great.

[Chillerman]

I think they look great.

Thanks Mac!

Yeah, these extend several inches past. My only concern is scraping the ends in tight turns on an incline. Is that an issue?

    That would be SOME incline ,,, you DO realize these are not "off-road" all-terrain machines 

The pipes look great 

[sandy]

Where did you find those silencers? Website??

[DavRed]

I want some of those!!!!! Yours look great. I would not cut the stacks.
Now is you are done testing and can supply the website where the rest of us can follow in your footsteps. That would be great...

That's the one! Thanks chrise2469  . Had them in less than a week.

The stacks are from here http://store.airflo.com/chrome-exhaust.html

And the tips http://grumpyscustomparts.com/

EDIT: One note, the silencers are 5" long. If your piggies are stock length, the shortest you can go on the extensions is 17 or 18".

[DavRed]

Ordered...
Money well spent I think...

[SpidyJ]

These look like pretty restictive baffles so how much hp are they sucking up?

The tips do look nice tho........  Let me know after a long trip if you feel like you lost any power.

Any other testimonies?

thx

They don't look much different than 18".  Watch out backing into curbs!  Hoser  
 
I would expect a power gain is more likely than a loss.  Hoser

I took a 60 mile ride today. I haven't noticed any loss in power. The three piggies coming out of the stock exhaust are only 3/4" each, the total opening in these silencers are much greater than the piggies so I don't think they are restricting anything to tell you the truth. They are just redirecting the flow, that may in itself raise the back pressure a bit, but the website says they are good for relatively stock engines up to 500ci! I'd say they are ok for our little engine.

[BF]

chillerman.......

How heavey are these "Slip-in Insert Silencers".  Do they weight much?

[3W-lonerider]

is that the price for each..or are they sold as a pair..

According to that site, it's a pair. 

"161100 Rex Slip-in Insert Silencer for 4" tube - Pair"

[Chillerman]

The box they came in said 3lbs on the shipping label, so they weigh less than 1 1/2lbs each.

They come as a pair for $78.95.


For anyone considering doing this, I have put over 150 miles in the last two days from 6000ft to 10000ft with no issues. Pulled up the mountain in 5th just fine. Gas mileage the same on that tank. My ears feel good  . I would recommend placing them as near the end of the tailpipe as possible to avoid sound waves bouncing around in that 4" pipe.

What kind of helmet do you ride with if you don't mind me asking.  I can ride most all day with my half helmet on, but with a full or 3/4, the drone used to get pretty bad.

Chances are you probly make more power with the baffles than without.  That's what happened to me when I put grumpy's restricter tips on mine.  Hoser


Before it was 96 HP

That's the same problem I have. I can't wear a full helmet at all without ear plugs. I did the glasspak mod on mine years ago and I'm really interested in this silencer. I was also thinking about the loss of power but Chillerman isn't seeing any. I'm also wondering how much sound it cuts down. I don't want it to get "too quiet" but cutting it back a small amount would be great if I could ride with the full face without ear plugs.

Yeah, I have three full face and a modular. I know the helmets are likely adding to the drone, but I don't want to go to a half helmet. I have audio set up in my helmets the way I like it now.

The website says up to 12dBA reduction. Mine are pretty quiet, then again I don't have glasspacks and the piggies aren't drilled. And you can always take them out  !

[BF]

This might be what I'm looking for.  I'd like to be able to wear my full face when I want to instead of being limited strickly to my half like I am now. 

I've got the ragnar cut on myValk and I used to have just straight 24" baloney cut extensions on the bike.....and the drone was horrible with a full on.  I've since put on 18" airflow extensions with the same Grumpy's tips that Hoser is running.....and the Grumpy's have reduce the drone somewhat.  It must be because the Grumpys upset that airflow some. 

I have a pair of silencers from MarkT that I wanted to try, but haven't yet.  Mainly because I was concerned of the added weight of the silencers.  I wanted to put them on as close to the end of the exhaust as possible.  I've only got two bolts holding each 18" tip on the bike now because of the ragnar cut.  With the weight of the Grumpys and with the added weight of the silencers, I was concerned about all that weight hanging off at the end of the pipe with only two bolts holding it all on, level and straight. 

Thanks of the tip chillerman.....I'm gonna give this a try and see what happens. 

[Jess from VA]

Yeah, these extend several inches past. My only concern is scraping the ends in tight turns on an incline. Is that an issue?

It can be, and I'll tell you where...... departing a steep gas station (or other) apron and making a hard turn onto the roadway while still on the apron.  I've nicked my 18" straight cuts this way.  Backing down on a curb can also do it, but often while backing up level, you clear the curb, but after shutting down, you lay the left pipe on the curb putting the bike on the side stand.

Let us know how it goes. I only have two bolts holding my extensions in as well and mine are straight. I wanted to keep them hidden. I think the can holds most of the weight anyway.

Thanks for the tip. I worry about pulling out of my driveway into the street because of the drop. I will be careful.

After getting all of my Valk's makeover projects done and completed and back on the road yesterday, I finally had a chance to take if for a shake-down ride today to make sure everything worked and nothing fell off.  One of the projects that I did was to install a set of those silencers in my extensions that Chillerman put us all onto.  One of the things that I wanted to check on that shake-down ride was to ride with my full face Aria Profile helmet on to see how well the silencers worked, or if the silencers worked at all.  

I'm very happy to report that I'm in love with my Valk again.  Those silencers reduced the note some, however the exhaust still has some rumble to it and most definitely doesn't sound stock.....but most of all......the drone is 99.9% gone.......GONE.....as in DRONE IS GOOOOONE.  I'm one happy camper.....and I can finally ride with my full face helmet again....or any helmet that covers my ears again.  WOO HOO.  

There is just a very, very slight hint of a drone, but my stock exhaust back when it was untouched and unmodified had just a hint of a drone even (I don't know, but I might be hyper sensitive to drone because of my tinnitus....drove me nuts with the old exhaust).  It's just as good as when my pipes where stock, if not even better.  I'm stoked.  

[Paxton]

Am gettin' me some!

Im going to try a set

Good deal BF  . I'm glad it worked out for you. I have tinnitus in one of my ears as well and I think that does make the drone all the worse.

[GJS]

Congrats on loosing the drone!

BF, who made your bags?
Those are the nicest looking saddlebags I've seen!

Cheers,

They're Mustang saddlebags.  You can get them studded (like mine) or plane without studs.  

http://www.mustangseats.com/Product/13300/Universal-Studded-Saddlebag-Set

I got them from Cruiser Customizing for right at $700.

They are identical to the Tsukayu "quick release Strong hardbags".  

http://www.tsukayu.com/QuickDetachableStrong.html

I don't know for a fact, but I'd bet that Mustang contracts with Tsukayu for the bags and then has their material put on the bag.  

I really like them....they're a very nice bag....lined and with good locks/hardware.  

The trunk is a Harley Davidson leather Tour Pak for the Softail Heritage.  It matches the bags perfect.  

The back rest on the trunk is from Corbin.

How close was the sound to the original OEM sound with all piggies in?  If indicated, use a Goldwing as a benchmark.  I have OEM pipes without the piggies and your are right, the drone sound when on a long ride is not to be enjoyed.  Have noticed any diffence in power?

No loss in power. 

What's been done to your oem pipes?  Just cutting the pigs off will not make it any louder......just a deeper tone, but not louder.  If your pipes are louder than a set of unmolsted oem pipes, then odds are, they've also had the rear baffles drilled out too.  Take one of your tips off and shine a light in the can to see what you've actually got there.  

Keep in mind that my pipes have gone beyond cutting the piggies AND drilling out the baffles.  They've had the ragnar cut done to them.....basically gutting the entire rear of the exhaust can.....thus making it much much louder than a set that's just had the piggies cut and the baffles drilled out.  

My pipes with the piggies cut and baffles drilled....

After installing the slip-in silencers, my pipes are now quiter than when they had the piggies cut with baffles drilled.  It's still not Goldwing quite......it still has a nice little growl to them without being obnoxious, but it alot quiter than it was.  I'd say it's a little quiter than it was with the piggies cut and with baffles drilled out.  

I like it.....it's not loud at all, still has some growl (I can actually hear birds chirping on the side of the road now like I could when they were in stock form) and best of all.....no more drone.  

I can't promise, but I'd bet that if you've got cut pigs and drilled baffles.....and if you install a set of the slip-in's, your pipes will be very close to the original oem sound of your pipes.  

Besides......if you don't like them after installing them, you can simply remove them without having to use a cutting torch or a hacksaw.  Just unbolt them and take them out.  

[Chillerman]

Thanks for the bump of the thread.  I rode to Montana and back to Colorado with these silencers in and it was a treat. No drone and I still heard the rumble of the extensions and Grumpy's tips. No loss in HP from what I can tell. 

[Red Diamond]

Let say that I want to install the silencers in tips the length of the stock Interstate tips. Is this something that can be done by reducing the length of the stock piggies and installing the Grumpy tips?

You would have to measure. The silencers are 5" long so if you cut the piggies down and installed some short extensions you might be able to make it stock length.

[3W-lonerider]

i have been running those silencers for 3000 miles now..can't begin to tell ya how pleased i am that the drone is gone. i just shoved mine up into the pipes as far as my arm could reach and tightened them down.
course i have 40 inch truck stacks, and i wanted so that you could'nt see the silencers

[Kunkies]

Thanks Chillerman.

Any input/feedback to your fellow Valk' addicts on installation?  Example:  did you have to take your stacks off the bike to install?  Also, after enlarging your photo of the pipes, it seems as though you decided to install the retention bolt towards the front of the bike, how come?  Lastly, given the stacks are 4" and the silencers are also 4" what did you use to insert into the stack, mallet with oil, soap?

So many questions, 

[O-B-1]

I took mine offf the bike. Gave me a chance to install new crush gaskets and polish up the crusted, hard to clean header pipes. The silencers are a loose fit on mine. Just slid them in, lined up with hole, and inserted the bolt. They have a welded nut inside and another supplied to serve as a lock nut to keep all from loosening with vibration.
