I have an 05 z400 with a K&N airfilter and extreme powerlid with a 160 MJ and the fuel mixture screw turned 2.5 turns. just looking to see what kind of exhausts other people have used with this bike. trying to get a little more power without being too loud. another z i ride with just put on a fmf powecore 4 with a header and its not to bad. i was looking at the fmf factory 4.1 with powerbomb header any advice?

 

just go for an fmf exhaust i hear they are reliable

 

yoshimira is nice, I like the trinity stage 4 pipe, thats what I run
it all depends on how much money you want to spend. IMO
