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. cheers

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.

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. cheers

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

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

1 easy-JUNK, probably has to do with the equalizing of the pressure between the cylinders. probably why yhe stock head pipes on vics have a crossover in them. alot of race cars run crossover pipes.

2 BEN-
q1- yes using a long bit and punching through the plate from the rear of the muffler. It will minimally help at idle but more noticeable under throttle--especially hard throttle. This done right is not noticeable. most dealers wont go looking for it BUT there is a risk if it is something Blatent that could have contributed to an issue. creating less back pressure cant cause problems by itself. Catalysts being removed is obviously easier for dealer to spot. But figure this the Stage 1 exhaust that is "49" state legal has no cats in the head pipe. I made mine not california approved! yeah. as for not getting all the matterial out...it is all metal and If you get a big enough chunk that you miss you will hear it audible and unless it completely seals it with no air passing it just restricts like it did before. If the engine still has proper compression no debris will get into the heads and cause problems/physics. IMExperience

Now if you hated your stock exhaust as much as i did you can pick up a set of stage 1 mufflers for a third of that price.

All motors (car, bike, whatever) need some degree of backpressure. Some require more than others.

A 2-into-1 system maintains more backpressure than a freer flowing 2-into-2 system. Loss of backpressure on our motors decreases the power by a small amount.

Annnnd that's not an opinion.. ;)

OP: you don't exactly have to spend $1000 to get a good exhaust. The Sideburner I posted about earlier can be had with some searching for as little as $350 actually. It sounds amazing, gives you a small boost in power... but it depends on if you like the appearance or not.

Again I will stress... even with the shadetree mechanic approach of drilling out your exhaust, you'll still need to get the bike tuned in order to eliminate the possibility of damaging your motor. Fried pistons cost a LOT more than a decent exhaust thumb up

Besides, our bikes came with heavy ass pipes that aren't exactly going to win any beauty trophies anyway. Stick away some coin here and there and do it the right way, I bet you'll be much happier in the end.


And seriously... this looks like crap:

Just asking a question here and hope it is valid. Also I know I am running a V92 TC and this is a Vegas thread with the 106 but wonder if this applied. My exhaust was loud enough for me (neighbors note when I I leave/arrive but don't complain too much) but the bike never had the all around deep sound I thought a V-twin should (when getting into it sounded like a vacum up front). That is until I changed out the stock intake (which had a K&N stock replacement and bug screen out of the box) for the K&N Big sucker (or wide mouth) and my gosh! As one person said "I can hear it gulping air". Of course along with the performance improvement being what I was after achieved, I can't believe how much stronger the bike sounds riding it. While cruising, she sounds tame but crack that throttle and wow! The horses are galloping!!

So, my question would be should be be looking more at intake/flash to achieve the sound he is looking for beings that would be cheaper then replacing pipes at this time or go the pipe route? And I ask this as the KP has my eye for a 2nd bike on down the road so my intrest is there... Thanks, hope this sparks some debate... It's slow tonight at work... hehehe :cool:

Sadly, no. I have RPW Slash pipes on mine. I knew I'd lose a tiny bit of power, but I loved the look and sound.

You only gain on 2-into-1 pipes.
Even with slip on mufflers? I've seen dozens of dyno sheets showing power increases with performance slip ons. Click on the 02-05 92 Inch Stock Motor Freedom Graphs and look at the dyno sheets. 2-1 gives the most increase but good slip on muffles help also.
Not all drilled mufflers are butchered like your photo. Mine looked great.
