Anyone have the E-Series Exhaust or the R4 Exhaust for the Z-400?
Whats the difference between the two? Any comments would be appreciated.....

 

I don't know but it looks phat. [img]i/expressions/face-icon-small-happy.gif[/img]

 

I have heard that the R4 is not available yet. I believe someone on the "other site" has the E series on their Z.

 

I have the WB E-Series Exhaust for my LTZ 400 and I installed the jet that came with the pipe. The machine is bogging down as if there is too much fuel rushing through. Anyone know what size jet works the best, or have the paper insert that was supose to come with the pipe? Appreciate it.

 

call white bros and ask them.

Dirt wheels did a pipe shootout in the march 03 issue. Both white bros pipes ranked as good all around pipes.

dif. between the two is as follows-

E series=
19hp@4000rpm
34.1@7000rpm/peak
97db
7.5lbs
disc style spark arrester

R series=
18hp@4000rpm
34hp@7250rpm/peak
95db
5.4lbs
screen style spark arrester

They tested with a 165 MJ for each pipe.

 

I got the E-series on my Z. I love it, it sounds great and gave it a pretty good feel in terms of more power.
