I can't take your stupidity anymore. It is really too much, outdone only by your stubborness. You cannot reason. Your telling me the 250S header robs more power than the 250S muffler which has an outlet the size of a drinking straw. You are flat out on crack.

In a broader sense, replacing headpipeswill notmake you power, barring any glaring defects from the factory, wihtout costing you elsewhere--it moves it. What a professional, full factory supported racer, with sponsor commitments to run parts out the butt has NOTHING to do with the 250S needing a slip on.

Here is where you reply telling me about your Mustang, DRZ, or fantasy football team for all I know...

 

KLXer, I'm with you! I ride with a group of KLX250 riders here in Arizona, some have the FMF, Muzzy or Two Brother full exhaust (header and muffler) and some of us have slip-ons, we all share the same gearing and carb mods, all weigh within 25 pounds of each other. We race all the time on the backroads, in dirt and on the street - and basically, nobody can pull away from other guy. You can only get so much out of a 250 and a 1 or 2 horsepower gain from a slightly larger header (or filing down the inside header weld - oh please!) ain't going to do it! The proof is on the pavement - not the research or what the dyno says. Now if you're the same size and weight as a horse jockey - yes, otherwise you are just deluding yourself - wake up and smell the cat food or get a KLX450r dude!

+1. I'd like to add that I.G. seems to have a fairly short attention span as well. I presented the same drinking straw argument to him awhile back, but he seems to have suffered some sort of amnesia, because he's still presenting a KLX300 argument for a bike with 50cc less displacementand a totally different, way more restrictive muffler.
Let me see, there are dyno figures at the HMF website that show their slip-on producing a 2.5hp power gain, but somehow the headpipe is still where you get the mostgain? I think not. Apply ausable power vs peak hp gain and the argumentfor the slip-on becomes even more convincing.
I wish I.G. would stop lapping-up all of BG's sensational advertising and actually look at all of the data.
