I want a new exhaust for my z-400, and im stuck. I dont know which to get, either the white bros e series, or the white bros r4 series.

Which should i get?

 

hey i had a e-series and i think there one of the best exhuast for a four stroke, my friend also had one hey said hey loves his e series.so i would say go with the e series, they sound really good and you can ajust the power and sound with the disc sistem.

 

The E Series has everything the R has, and then some, its usually just $10 more, thats $10 well spent.

 

ya, i rode a 400 ex with an r4 series, and i thought that it gave it a lot of top end power, but i also know someone with a 400 ex who has an e series, and it sounds awesome and gives adequate power.

 

Im thinking about getting the eSeries for my Z....

for those of you who have one - what are the settings for the jets ? What is it stock?

is it easy to do yourself ?

IM thinking about leaving the lid on and putting breather holes - like the White Bros. - that i have seen. just in case i ever get water or something ...

let me know - from your guys that have these systems in your bikes.
thanks.

 

I have owned both. You get a little more on top and a little less noise with the E. The R4 has a harder mid-range punch. If you're a trail/woods rider like me, I think the R4 is better.
Your sig has E slip on???
