If it increases back pressure, will effect your top end?
I love bottom end, but a giant surge n the middle/top is always exhilerating!

I must have missed that chapter too, because my YZ revs better with the stock silencer than it did with the louder, more open T4.

A good cheap mod, worth the money!

I overlooked your personal slam on the newbie handbook thing.
It is OK. I wrote the newbie book back when I was a newbie. This was back in 1972 when I started wrenching on bikes, cars & sleds!!
You completely misunderstood what I stated on back pressure vs. torque relationships!
I'll overlook your slam, THIS ONE TIME!
BTW, no Kouba for you!

I just purchased one today and would like to know what I can expect as far as any jetting issues etc...I'm running a WR e-series with 5 discs and would like to increase bottom end power. Install sounds simple...just drop it into the header up close to the jug right??
In order to get me geeked for the weekend...please tell me one more time about all the tremendous low end power increase!!
Did you guys experience any problems with the top end?? Did you need to add any more discs to compensate??

NO more discs
Just fit and GOOooooooooo!
and yes, seat of the pants dyno says, the bottom is better, without top end loss
