I purchased a K&N filter, jet kit, and White Bros. exhuast for my 04' Raptor. I did not get the full system, just the slip on. Should I get the header too or does it make that much difference? Positive feedback would be much appreciated. Thanks!

 

i think your fine, you would feel a difference if your motor was built with the header, but notmuch with stock

Thanks a bunch DaSandBomb. That's sort of what I was thinking too but I wanted to hear someone else's take on it.

 

Do you know if the WB slip on will even fit the WB headpipe? Or do y ou have to purchase the whole system? Just something to think about.

 

Not really sure but the slip on went on with no problem at all. By-the-way....it's VERY load compared to stock!

 

When I bought and installed the WB E-series slip on for my z400, I asked that exact question, and this is the answer I got. My parts guy said the only bike he knew of that you couldn't intall a WB header on with the WB slip on is a 400ex.
