2013 WR450F Stock "PowerBomb" Header & Exhaust Choice

4 posts in this topic

I just bought a 2013 WR450F that is completely stock.  What's the deal with the stock PowerBomb header?  I thought I read somewhere that it's not the same as the aftermarket one.  Is that true?  Should I get a full exhaust or just buy a slip on?  Which exhaust should I buy if I plan to ride my bike on the street?

 

Thanks

I bought a slip-on for my '12. It comes with a spacer to use with stock header or you take it out to use with power or megabomb. I guess the fmf headers have slightly wider diameter.. but I don't think it's worth the price for a small gain. The slip-on itself didn't seem to do much either.. but that was coming from an uncorked stocker.

Yes, ECU, tuner, FMF tune, GYTR throttle screw (came with competition ECU), uncorked airbox. 

 

I didn't see a big difference but I also didn't get much seat time all together stock or fmf exhaust. Mainly louder.. maybe I need to try different maps.
