I see that most on this forum choose the rev over the torque. I guess it depends on how you like to ride. I don't race, and I do a lot of gnarly, tight trails and sandy hill climbs. The Torque pipe works great for me. Air box lid removal is the only other mod I've done. It still rips when I want it to, though. Maybe not quite as good as the rev or PCpipe?
I have been considering that mod for some time now. Also a port and polish. The thing is, I have also been considering a 300exc mod. Heh. Im not sure how much more $$$ I should be dumping into this bike. I know that the performance is worth the money, but I will never see close to the dollars that I put into it when I go to sell it. If they could only ride a bone stock bike, then ride mine. That would be the only way for me to justify asking over 3000 smackers. I know that this bike is easy as hell to ride, and is downright fun, but, I have exceeded the bikes suspension capabilities (MX Tech), and the HP's aren't anywhere near the 300 exc.
The number stamped on the flange isn't likely the number you'll need to order it. Like '020057' isn't stamped on the mount tab.
The misnomer 'woods' generally applies to the kg-35/torque pipe.
fxmatt: Tell your retailer that you want a KG-35 pipe for your bike. If it comes in with a KG-30 stamped on the tab then he gets to return it and buy you another one!!
Be careful! Some catalogs call the KG-30 (rev) a 'torque' pipe under 220 application notes.
