How does your '99 wr400 FMF Q4 look?

Does anyone here have one on their 1999 wr400? how does it look and mount up? mine does not have the alloy mounting tab at the top of the can, but instead mounts using a band around the can. Also, the instructions that came with it say "installation for the Q2". It has stickers on it that say Q4, but those can easily be stuck onto any can. it has a visible spark arrestor in the end cap.
did i get a Q2 or a Q4?

So, i guess it's a real Q4. I can't imagine the seller replacing the pipe on a Q2 with another one and engraving the part number to a Q4 on it, that seems like it would be too much work. My bet is that it is basically a Q2 that FMF didn't want to spend the $$$ on redesigning so maybe they reconfigured the internal baffles a little and left the rest alone. They did mention that the Q2 had a gold can and the Q4 was silver, which mine is. Takes money to redesign and re-tool and they figured they would only sell a handfull of these, and it seems like i bought the only one!
Time to mount it and ride it! Gotta go do some stealth riding on an abandoned golf course on Maui!

So i installed the Q4, pretty straight forward. i ended up not using the aluminum spacer that goes between the subframe and the mounting band, because it fit better that way.
i have ridden it once, and i can say i am not that impressed with the sound level, i thought it would be quieter. and this is compared to a stock yz426 straight through exhaust i was running. the power is good, seems to be smoothed out alot.
i guess my expectations were high for it, i was hoping it would sound more like the stock wr400 with the pea shooter installed.
anyone ever adapt a down turn fitting to the outlet of this pipe? that would probably make it close to silent for those a few hundred feet away. if i figure it out, i will report.
