I just bought a Paul Turner Pipe with a Fat Boy Silencer, right now i have a stock expansion chamber with an FMF PCII Silencer ( it was on there when i bought the bike ) , should i install the Fat Boy or leave the FMF on?? What kind of jetting should i use. and oh, last but not least, what kind of power can i expect with the Paul tTurner pipe over stock?

 

With a good aftermarket pipe, a good air-filter, proper jetting, and possibly a few breather holes for the air-box, you can expect anywhere from 1-3 hp increase depending on the above variables.

 

id put the fatboy on. they work awsome and add lots a low end.
