Muffler-inexpensive mods to resemble sound of bolt ons

Are there any mods that can be made to the stock mufflers that will resemble the sound of the very expensive slip on cans ? I have seen and heard some great pipes on other stroms in the recent past that are ...well you know!
Can the center 1" section be drill or cored out for more of a straight thru affect ? What tools would be needed? $600-900 bucks seems awfull steep for another way that would achieve the same affect.

This site explains how to modify your muffler to make it louder. It does not explain why anyone would do this. For me: the quieter, the better.

I put 4 5/16 holes in the end cap of my DL1000, (North, south, east and west of the center pipe) sounds great. Not to loud and not to quite. Several DL riders who I ride with had after market high priced slip ons when back to the stock and drilled the small holes.
Just like the link shown before, but just 4 holes.

Cpope,

Did drilling those holes improve performance?

Don't really think so. I might have gotton a few mores MPG of gas.
But it sure sounds great. A couple of other V-Strom riders that have installed after market cans likes the sound so well the reinstalled the orignal and drilled them. Good luck, start with a 1/4 inch hole and see how that sounds before going to a 5/16.

Do you have to remove this bit [see pic ] before drilling anything?

And where do you actually drill? I have never removed the end cap [what I call the thingmy in the picture]

Just drill North, South, East and West. The wall is about 1 to 2 inches deep between the large middle exhust and the larger outer rim. I started at 1/4 and went to 5/16, 4 holes. Some go latger and more holes but 4 holes was perfect for me.

You don't get the same effect as high quality exhaust cans! Yes you will achieve more noise........more like a leak IMHO. You get a raspy, louder, leaky and farty tone. You lose signifigant weight, and achieve a more narrow profile with new cans too. As for paying $600-$900 for exhausts.....stop looking at Staintune, ackropovic, Remus etc. Scorpion, Two Brothers and Leo Vince are between $400 and $500 for "dual" cans. I have the Leo Vince cans, and they sound incredible. Baffles in sounds about perfect...baffles out sounds bad ass!

ALLOT of people that have done mods to their exhaust, wish they hadn't later down the road. My 2 cents!

Muffler-inexpensive mods to resemble sound of bolt ons

Well folks, thanks for all of the replies. I did the 3/4 inch core drill first, which sounded good. The immediate thing I noticed is it's like pulling the cork out of your dirt bike muffler you put in when washing the bike.... THEN forget to pull it out when trying to start it. It will run, but much better with the cork removed. I think the core drill approach more resembles or mimics the aftermarket pipe design in the airflow department more so than the small drilled holes in the internal end cap. Sort of reminds me of the road king before and after putting the mid range cams in.

More MPG that someone mentioned..... well, have not check that part out yet, but more free flowing exhaust would tend to make me think it would help the mpg.

Just my thoughts.

I guess also, what I have read on all of the can instructions is that the maps do not require fatting up, they do this sort of automatically matching increased fuel delivery with increased air flow, resulting in more torque/hp.

Don't forget the PCIII, which adds about $200 right?
