If I cut the pipe and dig out the cat, I suspect that that will cut down on the heat. The oil is cooking in my transmission. In 4 Ultra's, this is the first time I've seen tranny oil go black. I figure it has to come from all that heat from the cat.

The bike runs just fine for what I use it for. But, I need to remove that heat source.

What is your experience with removing the cat from stock headers?

Will I have to take the bike in to have it tuned?

If this is not a good option, what do you suggest to illiminate the cat from the headers?

Thanks all!

 

With the mods you already have on your bike, taking the cat out will definitely need a new tune. TTS or SEPST is the best and cheapest way to address all your fueling needs. They have base maps that will address your fuel and timing changes to get you close then you can auto-tune to finalize the VE tables.

 

Has anybody tried taking the right side muffler off and using a long drill to remove the cat? I know it wouldn't be as clean a remove as cutting the pipe, But getting most of it would be an improvement. my wife rides with her foot up on the highway pegs I installed for her. She says the heat is terrible around the cat area on her 2010 Trike. I'm not convinced you need an expensive tuner if you remove the cat. That's why they call it an ECM, it controls what it picks up from the sensors to a great degree. Check your plugs to see how lean it runs afterwards.

 

Several companies make replacement headpipes without the cat. Cost more, but you know it will work right. Plus, you have the original if you need it. You may want to look into the implications of removing the cat from the stock pipe in relation to the position of the O2 sensors. I have read that can be an issue.

 

I change to Vance & Hines Power duals but had to go with their 2009 version because of the size of the 02 sensors. Reason being I was putting the thunder max commander on. And the heat coming off the converter was to much for the miles I ride. But my Buddy put on the same power duals with the monster ovals and the Dyno Jet 5 without the censers on his SG.

 

Better option than removing the cat = Get aftermarket pipes.

 

Go with the V&H Tru-Duals, get rid of the goofey stock pipes.

If you get one of the pipes above. Make sure it is for 2010 model. The 02 sensors bungs are in different location and different sizes between the 09 and 10 pipes.

 

My Fuelmoto headpipe (those in your photo) has bungs for both 2009/2010 bikes, you use what your bike need and lock the others.

 

The problem found with "Gutting" the Stock Harley head pipe on the 2010 Touring Models is there might be cross talk between the O2 sensors.

Harley moved them down on the 2010 models and when the Catalytic element is removed, the O2 sensors don't have the material that separates them. The after market Headers have addressed this problem.
