After talking with PaiN and a year of deliberation, I decided to take the Cats out of my exhaust. The undeniable heat on my wife's right foot just shouldn't be there as well as the added heat to me that made the bike unrideable without removing the hard lowers in the summer.

Here is my initial thoughts after taking a 20 mile ride today.

Removal:
A little harder than I expected. The second one was easier once I realized the trick. But I'll tell you, the drilling of the numerous holes was harder on my bit than I thought it would be.

Sound:
Probably a hair louder(not much really) and a bit deeper and a bit more throaty. Not exactly what I wanted, but more to come.

Ride:
About 42 degrees out. Rode great, sounded great and had no popping at all. Did I notice a difference in torque? To be honest, maybe a little. Big difference? Not at all. Totally rideable as is. By the time I was done my 20 miles, I realized that I just needed to be around 100-200 rpm's higher than I normally am when cruising.

Heat:
Well, it was 42 degrees out so I can't really comment yet. I will say that I used my heated seat for the first time. Even at 42 degrees, I usually use the engine to heat up my legs a bit to keep them warm. That did not happen today. So, not scientific, I need to ride in the heat to really tell you if there is a big difference.

Now, I will have to update you a bit later, depending on the weather. I ordered the 158 Thunder Torque Inserts from DK Customs. If they do as they say, these little nuggets will return my sound to exactly where it was and will return some or all of my low end torque. I am not expecting all, but some of it back will be exactly what I hoped for. Cats/Heat will be gone and the bike runs great and gets me to where I need to go the way I want to get there. Also, once I get the TTI's in, I will decide if I need a dyno or not. Honestly, with no popping today at all and once the TTI's are installed, I think my current map will be just fine.

I will certainly keep you all updated for those who have been deliberating like I did.

More to come.....

I just got back from dropping my forks and rims at the shop so I'm that much closer to having the bike back together and ready to run.
Over this weekend I'm going to pull the rear shock, lube the pivots and place the DK Thunder Torques in the mufflers.
I'm not in the mood for experimenting, I'm placing the Torques and getting it dyno-ed in the spring. If the bike runs obnoxiously loud or has crap power, I'll skip the dyno and replace the full exhaust then have it re-tuned.
I am very happy and encouraged about how your de-catting went :)

Your bike is going to sound great and you will have plenty of power.

Oh by the way. Calling for snow on Tuesday.

I just want to ride now.

Interesting. Still have my cats and have never been able to get rid of all my decal pops. Am running baffles so wonder if the Thunders would alleviate this. Never pulled my cats s I was afraid the popping would get worse

Curious as to where you are placing these.
thanks

decal pops fix could be a simple fix maybe. Check your exhaust flange bolts. I had to tighten mine 3 times before I stopped my popping

DK recommended the 158 Thunder Torques (and for davefarias's also) they will be placed in the 2.5" exhaust outlet of my Miller Mufflers.
In fact, I'm going to place them as soon as I finish this coffee ;) and yes I'll post pixs

What do they go inside the muffler outlets right at the tips ?

Latest Update

Update:

Installed the Thunder Torque Inserts W158's. They are 1 5/8" wide and they install inside my 2 1/4" pipe. When I put them in perpendicular, they sounded just a little too restrictive. So I called DK Customs, who have been super helpful. I asked if they could be turned at an angle and if they would still work. They told me that they do that in some of the Harley pipes and work great. So I set mine at about 40 degrees. Perfect! Sound is just right.

I know what your all wondering.... Did I gain some low end torque back? Yes I did. The bike feels great. I will still play around with different angles in the spring, but to me my bike feels and sounds just like it did before I took the cats out. Honestly the sound is a bit deeper and a bit raspier. Not a huge difference. But I have side by side video comparisons, so I can tell from that. While riding, I really don't notice much of a difference.

Was it worth taking the cats out? So far yes. I really can't answer that question until June or July when it gets warm. That's the real reason for taking the cats out, the heat.

If the heat is significantly reduced and the bike still feels the same. I will be super happy.

I will let you know when I know.

Well Dave .....I again am totally f-ing encouraged by your report. :D
I hope that the de-catification and baffles save me from having to buy a full exhaust system and another summer of suffering.
I also think with a dyno tuning touch up you(we) may actually end up with better performance using the Thunder Torques.

Uhmmm, the cylinders on a vic 106 are aluminum, are they not? Over tightening exhaust bolts could lead to stripping them, and I am fairly sure THAT would be much worse then an occasional deceleration pop.

I said "tighten" I did not say reef on them or go crazy on "tightening" them. Decel popping is normal caused by air seeping in the exhaust threw flanges.
If you try yours I'll bet you a buck there loose

by the way there have been no steel cylinders or head since 2000 on any bike made in America

Awesome thread. I too suffered from tremendous amounts of heat last summer with my set up. My fix was to remove lowers and deal with the wind.

Are the slipons hard to take off? I had the dealer install everything on my bike.

I don't think so. I've gotten to where I can have them off in 10 minutes now if I take my time. Remove saddlebags, remove main clamps, remove heat shield clamps, remove rear bolts, slide/twist off.
