I read it was brutally loud.

------------------

99 WZ, all YZ mods, de-octopused, OEM YZ tank and IMS seat, jetting by Clark/James, got forked by Pro Action, DSP airbox, PB Header, Stroker SX-1 SA, Thumper Rad Guards, Acerbis Hand Guards. Moab, HERE I COME!!

the pipe is a motox pipe for sure. i hope you don't take it anywhere near a road.

Taffy

I have one on my 426.

Bad things:

Louder than stock.

Not sure if it is worth $450 compared to other things you can spend your money on.

Burns your pants (but they all do that).

Good things:

Impeccable craftsmanship and finish.

Fit perfectly, installed easily.

Perked up mid range a noticeable amount, loss in upper revs not so noticeable.

Gasketless junction between header and tail section.

Removable spark arrestor included.

Allows access to oil filter (but they all do that).

Louder than stock.
