and yes i searched, before u guys flipped a Buddha Loves You. anyways, how does this work? and where do u drill them at? also, what does it sound like?

SEARCH NOOBCAKE!!!




HA!!!  I beat NGFL to it!  WOO HOO!


Anyway...  Most of the threads I've read about it...  people say it sounds like crap.  You basically drill holes at the end of the can...  you know..  on the black part around the OUTLET of the can.

When I had my gs I did this, at first I thought it was kinda cool, then 15 minutes later I realized that It was really crappy sounding.  Then I was always getting off the gas around people cause it was embarrassing. Dont do it, install a real muffler if you want some noise.

You didn't search hard enough

I share a garage at our apartment complex with a dude who bought his GS500 after I got mine.  He realized one day, after we went for a ride, that his sounded rougher than mine.  After around $400 worth of mechanic bills (much of which we could have done ourselves had he not been too nervous  ) he realizes that some yahoo before him had drilled four holes in the exhaust.  End result:  putt-putt sound, bad mileage (his bike is newer than mine but much worse), back fire during deceleration, and slightly weaker power.  DON'T DO IT!  Suzuki chose the pipes that they did because it was best for the bike. Unless they are damaged (which drilling holes would include) don't futz with them.  My op, though  .  Grain of salt and all.

Blah Blah Blah...

If you want to drill holes in your exhaust, do it.  Understand though, that if you want a deeper, throatier sound, you need to remove a lot of material.  It's not enough to merely drill a few holes.  Yes, it will be louder, but still puttity-puttish.  I drilled holes, then removed the material between the holes.  The sound is deeper, throatier, and pleasing.  Also, you will need a rejet, and installing K&N or Uni filters will help with the sound.  My bike is louder without being obnoxious. 

If you don't trust me, ask the guys that went to Deal's Gap last summer.  They liked the sound (unless they were simply being polite).

Now, where to drill?  Well, if you look in the end of your exhaust, there is the large diameter outlet for show, and a smaller diameter pipe that is the actual outlet.  The metal between the inner outlet and the outer is the material you remove.

The picture is the work in progress, the exhaust I have now is all drilled, filed, and finished.  Sounds good, take effort, and is a FREE mod.

I'm just curious:  Why have a muffler then?  If you are going to remove all the parts that control airflow, why not just put a straight pipe on it?  Wouldn't that be easier?  Is there some value in keeping the large casing on the pipe?     Honest questions here.

it is easy to build something similar to what  vance & Hines did.  basically all a glass back is : a piece of pipe with a thin sidewall of about .075  .  then you have a perforated tube that you can make out of that thick mesh and bend around and tack or spot weld. it fits up to the exhuast pipe usually over it then you pack fiberglass around it. you connect the perforated tube to a round piece of stock that will slip into the can and screw in or rivit  with a tailpipe on it. there you go .

drilling holes is really just a waste . if you can afford the luxery to have a motorcycle  then you can afford to do it right. but whats the point of doing somthing wrong anyways?

why dont  we start a survey or database with nothing but exhuast sounds from different types of exhuast. I know there is already a vance and hines sound online , and I to have a rebuild or modefied vance and hines that I have a sound clip of and I know a lot of others have it to. I am curious to hear what a drilled stock exhuast sounds like.  and what some of the other pipes sound like.

My stock exhaust is full of holes but I don't have anything to do with that,
except maybe dropping it on it's side in an accident few years back.
I could record how it sounds like

it sounds better than the pipe i had on my bike back when i heard it, but i now have a sorpin and its nice and mellow, but still pops on decaeration (need to twick the carbs

For $50 you can send your exhaust to me and I'll put a straight core through the muffler and pack it with stainless.  For $120 I'll cut the casing off the stock muffler and put a carbon fiber sleeve around it and you'll lose a lot more weight.

You'll get a nice, even sound...though it will be louder it won't sound rough and raspy like cutting holes in the stock muffler.  Plus, it'll look stock.

mak how much would it cost just to send me a carbon fiber sleave that could fit in place of a V&H sleave. I have the c17 alloy sleave on there now but its the same weight as SS . I can give you all the tolerences on the wall thickness,  the ID, and OD.  or if you have them for the sleaves you use I could see if that would work or not.  and I have never worked with CF can it be riveted?

I need the sleeves inside diameter.  They're round, right?  I can't do ovals or funny shapes.

they are round. I will get that info to you. 

The previous owner drilled my exhaust and I always liked the growl it had and never had any mechanical issues. I averaged around 52 mpg.
