If it weren't for the stock pipe on my 300 nearly breaking in two, I never
would have switched to the FMF Gnarly pipe. Thanks KTM! I took it for the
first spin last night. On the initial road section, it was hard to perceive
any difference. I could tell that the very top end was softer. As soon as
we got into the dirt, the improvement was obvious. Substantially more
torque at low RPM. I could run almost a gear higher in all conditions than
I could with the old pipe.
I'm thinking that this will dramatically improve my gas mileage. I can run
in low RPM and barely crack the throttle open now.
Before I welded up the old pipe, I had started fouling a *lot* of plugs.
I'm thinking that the plug fouling was somehow caused by the pipe cracks.
Perhaps it messed up the resonance timing enough to result in
(something-something)? The cracks were at the u-bend about 8" from the
cylinder.
The new-found torque coupled with the autoclutch makes this bike criminally
easy to ride anywhere. The only down side is cost. I also needed to buy
another E-line guard.
Soon for sale on E-bay. "Stock KTM pipe & E-line guard. Only used lightly
by senior rider. "

P.S. If anyone here wants just the stock E-line guard for '06 (& other
years) KTM, let me know. I'll make a great deal.

Save your cash on the e-line pipe guard and just blow out the dents.

Too late, but definitely an option. I'm sure I'll be doing a little of
both. I prefer not to have to remove dents annually. A pipe guard should
push it out to every 2-3 years.

I don't mind most dents unless I start losing noticeable power from
the dent. The problem is that I had with the CF pipe guards was I
still got dents and creased the pipe at the last bend just before
where it mates to the engine. Dents are easy to remove, but the
crease hosed everything.
Now my pipe dent removal guy is a friend named Skip. He uses a
profesional bicycle maintanence stand as it clamps easily onto the
stinger and allows adjustment to any angle. Skip made custom clamp-on
pipe plugs that work great. One of the plugs has a pressure guage, a
needle valve and air hose connection. This allows him to use the
needle valve to stop any expansion instantly.
Anyway, happy smashing to eveyone!!!
