250-500cc FMF Gnarly impressions

Was wanting some feedback regarding FMF Gnarly pipe. 2002 WR250. I ride mostly dual sport with occasional trail. I would consider mysely a lugger not a revver. Top end is only used for cleaning out after 30-40 miles of lugging. What kind of low end gains if any could be gained? Stock motor. Will be installing new top end, might as well do reeds as long as it is apart, have FMF TC2 spark arrestor, and Lectron carb. Gnarly sure looks sweet, but can't justify it just for the bling.

Thanks,
Mike

I had one on my 02 a few years back and loved it for lower speed tight woods,rocks etc. Most gains were at the bottom. The stock pipe didn't last very long in the rocks so most of the time I owned the bike I had the Gnarly. Not sure of the benefits if your doing mostly dual sports though.
