Has anyone with a 400EX installed the Silent Core insert into their WB E-Series pipe?
If so, did you notice much performance loss and/or did it effect your jetting if you had re-jetted your carb?
I just installed my pipe, I have an K&N airfilter and plan to drill (6) 1" holes in my airbox lid. With this combo I suspect i will be re-jetting at least to a 155-160 MJ.
To be legal a few of the places I plan to ride, I will need to install the Silent Core insert to get me hopefully down to the 96db limit.
I am curious if the insert would effect the performance to the point where I would be running to rich.
Thanks!!!
