I made a test pipe myself for my 2010 Road Glide.
Make yourself a mark down both sides and cut the catalyst in half, use a 1/4" drillbit to drill holes as far out along the edge as possible , staying as close together as you can.
Then grab the catalyst media with some needlenose vice grips or something comparable and keep tearing, yanking and cussing the whole time.
Bear in mind that the catalyst media is glued into the can.
I used a die grinder with some "flap wheels" to polish out the adhesive and the rest of the catalyst media that is still glued in the can.
It's a messy job but well worth it.
Wear a good dust mask.

I have a Nightstick on mine with a PC V and a S/E Ventillator A/C and I think it sounds great.
Not loud at all, barely hear it at hiway speeds but has a reasonable growl when you get on it.

 

Both of the o2 sensors are in front of the cat on the 2010 2into1, The cat would in no way seperate those two sensors. If you have ever cut one in half you would never have made a coment like that. That is flat out Bull on the 2010 2into1 exhaust. Yes, you need a tuner after and it runs much cooler and sounds better not muffled.

 

just for ***** and grins, here is a sound clip of the nightstick without a cat:

nightstick

and now, shameless plug, i have one for sale in the classifieds

 

duplicate post....

 

........and what cams might them be Skratch?

 

them would be stock. my bike is almost completely bone stock. i still have the stock ac, no fuel tuner, cams etc.....

the only thing not stock is the catless head pipe, and the nightstick.

oh, and the boom audio speakers

 

Again, tuner is not required after cat removal.

 

I cut my collector in half by hand with a hacksaw, drilled the cat material out with a quarter inch drill, scrapped the remainder of the cat material out with chissel.
Total time maybe an hour and a half. Had it rewelded. Total cost $20.
Wrapped the rear cyclinder pipe and the collector with header wrap. cost $14.
Runs and sounds fine, and a hell of a lot cooler, without spending major bucks. Just like we did in the old days.

 

I've done the same thing to my 2010....she sounds pretty good, but she don't sound like that.
Maybe it's the difference in the amount of discs in the muffler, as I am still running the setup as it came out of the box.

Thinking of trying the extra 5 discs, and maybe even the open endcap on mine to see if that helps some.
I am assuming that you have experimented with that kit also?
If so, how did you like those results?

 

I put the nightstick on after the cat removal and it needed a tuner.So you must of got away with it with the stock muffler?
