I mentioned in another thread my thoughts on replacing the OEM cannister with one off a larger displacement bike, much the same way as the DR650 nuts (me included) used the Ti cannister off a Gixxer 600 to replace the OEM on the DR.
My reasoning for going that route is because of the last 2 experiences I've had with FMF.
I'm a lot closer to 50yo than 45yo, so I admit my memory isn't want it used to be, but I honestly can't remember ever encountering worse customer support from a company in my entire life.
The WR250X full exhaust system I ordered arrived and I cut myself twice just removing the **** thing from the box because there were stainless steel burs all over the header where the guy welding left the wire sticking to the pipe. The header didn't fit into what I call the "mid-pipe" properly, and required modification with a Dremel before I could get it to fit.
There wasn't a single mandrel bend on it, and it looked as if it were built using a $25 combo-deal from Harbor Freight for a Tube Bender and Welder. When I documented it with lots of pics and emailed them (nicely) asking why these obvious defects were shipped out I was told to f-off, but not in nice words like that...
FMF is one of the larger companies in motorcycle aftermarket and they know they're one of the only companies able to make a large selection of parts for nearly all bikes out there...They also know they can get away with stamping out shitty parts, call them "compatible", and tell people to piss off if they have problems.
The DR650 header I ordered? the "connection" point to the exhaust port on the engine wasn't straight. The pipe was bent wrong (to the point it interfered with the oil cooling line and would have burnt through it if I hadn't re-routed the oil cooling line) and the pipe split at the curve by the front down tube after 230miles. Again, well documented with pics at the time, emailed them, and was told to pound sand.
What ticks me off most is that I've never encountered a problem with one of their 2-stroke expansion chambers/silencers...they've all been absolutely perfect. Perfect fit & finish...so I know they're "capable" of producing a quality product.
Sorry to hijack the thread.
