Default Debaffle or Remove stock Exhaust

I have a 2012 Vegas 8-ball, although they did make the exhaust to have a deeper note on the newer models, I would prefer it to be louder. Has anyone tried to debaffle the stock pipes? Also, has anyone removed the mufflers completely and ran straight pipes? I know that a remap will be needed and air filter, but is there damage that could be done to the bike if I wait to do this? Should I just wait and buy the full kit? I only have 130 miles on the bike thus far and would like to make sure that I do not interfere with the 3 yr warranty on the bike. Thanks in advance for any input on this.

You can search on here about drilling stock pipes. It makes it a bit louder but not really loud, you can also remove the catalytic converters which should also up the db. How much louder? I'm not sure.
When I changed my exhaust, I decided to see what it would sound like with just the stock head pipes first, and it sounded like crap, a raspy gargle basically. So anywayz, I now have the Bassani 2>1 with no tune. Just unplugged the o2 sensors. No problems on my bike.
I also waited until I went through the engine break-in period first before I did anything to it. It seems all good so far !! But I am getting a power commander with auto tune this spring to ensure it runs nice.

I pulled my can off my 2 to 1 and used a 3/4 concrete bit to remove my cats. I pre drilled a small pilot hole then wallowed it out. I also modified the baffle to increase airflow until i got the sound i wanted. It takes an S&S intake and some work but it is well worth it. Intake by far best 300 dollars spent.

You could drill the stock exhaust out, but the release of the extra backpressure would still need a retune.

And honestly, you'll save a LOT of weight by getting different pipes. Less weight = better performance.

Now, when you go to select new pipes, remember that most all pipes available are small diameter pipes, so you won't get a deep, rumbling sound. The ones that do give you that deep, rich sound will be the RPW Big Slash, Hardkrome Sideburner, and the Conquest Customs Octanes (Octanes not quite as deep as the others, but much louder and impressive IMO).

Also, the shorter the pipes, the louder they will be. The Arlen Ness Slashness pipes are considerably longer than the RPW Slash or Santa Rosa pipes, so while they look the same, the longer length make the Slashness quieter. I have the RPW Slash pipes and they are loud, plus they sound great.

If I had it to do all over again, I would only buy the Conquest Customs Octanes or Ground Pounders. Not only do they look mean as hell, sound mean as hell but they are wrapped pipes. I've found that most all aftermarket pipes for our bikes tend to stick out in a way that it's really easy to hit or rest your leg on them. My black Slash pipes have permanent marks on them in 2 spots... one spot from my jeans flapping against them while riding, and another spot where my jeans touch them when my feet are down.

At stoplights, i have to extend my right leg out a bit to avoid the radiant heat... wrapped pipes throw off a LOT less heat.

I would like to piggy back Bandit in saying that the 2-1 does give a much deeper tone and once the catalyst's are removed and the baffle altered from stock configuration by grinding off the stock spot welds holding the 12 inch cone(power robber) mine has an excellent throaty, deep and loud with or without extra throttle. Not to mention I have little to no popping on decel with the stage 1 Victory download...since I removed the cats.

Also, 2-into-1 pipes are the only way to get a performance increase.

Exclamation This is where I'm at and need a little more info.

So I have removed the stock muffler to take a look inside. Internally it has a plug roughly the size of the stock outlet (looking from motor side to outbound side) and looking through the other way appears to be the same thing. So I guess that the exhaust exits the motor passes through the catalyst (more on that in a sec) Goes into the muffler and the is diverted through a baffle to the external part of the muffler for about 12 inches and then trough another baffle and out the stock outlet.

First question- If I drill a large enough hole through the front and back blocking plate of the muffler the exhaust should pass through it right? And this should have the least affect on back pressure. (I'm not talking about drilling the exterior plate on the muffler which most people do. I talked with my Victory dealer and they informed me that if a warranty issue came up, they would need to take pictures of the bike and if the holes are visible on the exhaust and the exhaust could be attributed to the issue, my warranty could and would be denied.

Second question- With the mufflers removed you and see the catalyst at the end of the pipe. If i drill that out, which I would have to do completely or pieces from drilling could end up on the motor side and when started could become logged in the pipe causing a blockage. This would also IMO cause the most significant drop in back pressure and affect the tuning the most.

I know that getting a new system is the way to go but right now, and probably a long time from now, I can't spend the 1000 to do it right. My objectives are to get more sound with the least amount of money and still retain my factory warranty. If anyone has done this or know of a inexpensive way to accomplish this let me know. I have the mufflers off now and ready to do work.

The pipes I posted I cored (hole sawed) the block-off plate. Mine only had the one. Made little difference in the sound.

Sorry to butt in on this conversation, but can someone explain to me why this is? Doesn't have to be here, can be PM if you don't want to clutter up the OP's thread.
Thank you.
