I ride a 2010 Road King and I want to get the cat out of the header pipe. Of course, this will be for track days only and not street use.

Does anybody have suggestions on brand names for full exhaust systems or header pipes without the exhaust? I'm thinking will cut down on some of the heat and allow the engine to breath a little better.

 

Installed a jackpot headpipe on mine uses the stock heat shields, SE air cleaner, rush mufflers and Vied's... very happy with the results to date.

 

Put an 09 headpipe on my 2010 Ultra, a big improvement. no more cat. $35.00 on e-bay....

 

I thought that the '09 oxygen sensors were a different size from the '10 bikes?

 

I believe you are right...the bungs are different sizes. However if you run a tune on the bike you may not need O2 sensors anyway

 

We offer True Dual head pipes that are ceramic coated inside and out. You can expect a 300 deg reduction in heat. The 2010 bungs are a different size than the 2009. A lot of systems, including ours, comes with both bungs and plugs for the ones you don't need.

I'm running an 09 pipe on my 2010, PC-V from Fuelmoto, 02 sensors are eliminated and not needed with this setup. 09 pipes are pluged where 02 sensor were. Woods 6-6, FuelMoto map, JackPots, run like a bat out of Hell...... much cooler and sounds way better than stock.....

 

Roger that! Congrats on the set-up, I like the idea of the Rush pipes being ceramic coated.

 

What is being done to the computer after the changes? When removing the o2 sensors, What other changes do you have to make?

 

Can you either drill and tap or use a reducer to get the right size O2 bung for a 2010 or 2011 103? I would think so, but don't know what threads are used, or the sizes for the years.
