I am new to the Harley world and purchased this bike about a week and a half ago with stage 1 completed at the dealer. Currently this has a screaming eagle intake, screaming eagle tuner and screaming eagle street cannons. I am looking into replacing the header pipe to remove the cat but have noticed a lot of header pipes take a lot of room up behind the engine. Typically this would not be an issue but the problem I am having is that the bike has the rear cylinder cooling fan installed and wasn't sure if there is a header pipe that would fit with that installed. I would like more performance (of course) and a louder sound as the street cannons are quiet at idle and sound louder when under load. I have about 1200 miles on it so far. Any help or advice would be appreciated

 

You didn't say what year, but it looks like a 2017. That being said, changing out the head pipe to one without the CAT in it will void your warranty, just letting you know. actually the factory 2017 head pipe is a very good design and is hard to top for a stock through Stage II engine.

 

Sorry missed some key facts there...it is a 2017 Ultra Limited.

 

Supertrapp's Unfiltered head pipe 2:1:2 is an exact match to the stock headers minus the CAT. Have alook http://supertrapp.com/product_sections/cat.asp?CatID=92
