'05 WR450F Exhaust Silencer

[MKP]

I took out the Exhaust Silencer (Baffle) and the spark arrester of my new '05 WR450F. ?

Considering that I have no noise restriction where I ride (Atacama Desert), is there any diference in power delivery riding this way compared to using and after market silencer ? ?

Thank you

I took out these parts as well before I put the FMF Q on mine. There is a slightly better delivery of power in low RPMs with the FMF compared to just the baffle and screen removed.

hi i'v just bought a 2005 WR450F and i've been looking at uncorking it, did it make your bike loads louder? did you alter the jetting? and whats with the grey wire under the seat?
