I ride an 09 Ultra and am wanting to reduce heat and if power is increased all the better. I recently read that you can drill out the catalytic converter in the head pipe and it increases both. What experience and/or advice do people have out there? Is it better to replace the head pipes or is it fine to just drill it out?? Cost for either vs. gains?
if it was bought it caly it may have a cat ? not sure though.best bet for heat is a good stg one,fuelmoto is a highly regarded sponsor of this site and has very good prices for stg 1 kits .

Thanks for any help here!
Your 09 Ultra shouldn't have a cat unless it is a "California model".
My 09 SG from Calif. had a catalytic conv. It got so hot is was almost dangerous. I switched it for a 49 state header. What a difference! Bike is all stock otherwise. Runs better too.
I dont think the 09's have catalytic converters, Just the 10's

Just up to the 2009 California Models and ALL International Models have the Catylitic Converter. The 49 State models run a regular Header pipe without a Converter installed.
All Models begining with the 2010 year, regardless where sold, have a Catylitic Converter installed in the Header Pipe.
