I been told by a few folks that Bill at Bills Pipes sold his pipe design to FMF some years back, but no one has confirmed that.
I wonder what kind of torque curve the FLEXPIPE SPECIAL produces?
I have been looking for that photo of that Flex Pipe exhaust for 3 weeks now.
THAT WAS THE FUNNY DAMN THING EVER I STILL LAUGH TO THIS DAY OVER THAT .
FIND THAT PIC PORTA!!!! I will make it QUAD OF THE MONTH!
OMG I LOVE IT !!!!! QUAD OF THe YEAR AWARD!!!!
Your Awesome WestTex!
Nice!!!! are there any dyno sheets of this pipe.
Cant post em, make too many Pipe Builders would cry at the results ...................
Wow.... after seeing that I can't wait to see the silencer?!?
Silencer?

Now thats just crazy talk !
Thats the greatest ever!! and its obviously been out shredding some mud!
I bet the silencer is and old Cherry Bomb off a Camaro.
Dam thats bad.Thats worse than the stuff seen around the farm.

On another note does anyone know how to modify the line colors on the dyno sheets?I can,t follow or differentiate them worth $hit.
Wow... There's a dyno sheet for ths pipe?!?
Any word on getting them dyno graph lines more legible??? Still can't see them worth a
Is this flex pipe the "hillbilly zilla microwave pipe" you guys were refering to or are they two seperate pipes. I want pictures of this microwave metal pipe.---still think you guys were smoking something.
Quadman, that was over 5 years ago on the old site...pictures probably don't exist anymore, but it was real.
I think he had it on a hybrid built before the hybrid mods were more or less standardized, so the whole bike looked pretty redneck not just the pipe.
West Texas King-----The real question is could the microwave pipe warm up my toaster strudel and hot pockets while doing 60 mph up the face of sand mountain. Now that truly would be a pipe!!!
MMMMM some hot Possum Etouffe while on the fly. One of you guys has got to make me that Hill Billy pipe.
FMF had a first generation pipe that was better then this thing they sell now but compared to the lrd and above brand it doesnt even hold water. It was like the p.t. pipe. I raced my brother on his bike and he had a trinity stave IV setup with the trinity pipe and silencer. My stock bike with a pipe and reeds and good jetting at the moses lake sand dunes when we would race would keep with him until we shifted to 4th gear and then he would start pulling me. So either that pipe was ok or the trinity is just junk idk either way the fmf was more of a mid - midhigh pipe and would flatten out when you got probably 7000-8000 if i had to guess I never tacked it. We both would beat banshees that had quite a few mods done to them although this was back in 1995 or 1996 so banshees have came a long way since then. I think the pipe was just called fmf rev pipe or plain gold series back then not fatty but i might be mistaken. I know it doesnt rev like the new pipes out now but back then it did good and is sad that fmf changed a ok design to a crap one that overheats your quad. Maybe Emler had more hands on back then.
Sorry was supposed to be a quote but im not to computer savvy. I guess thats why I work in a warehouse
There is video of the hill billy deluxe. Him and Carl,racing up the dunes. I think it was a video from joe rock
LMAO HBD , almost forgot about that one.
Ya the video was out at China Wall, About three runs later I chewed up the last port bridge that was in the intake and spit it out the pipe somewhere on the hill. The motor ran the rest of the trip, but there was no question it was hurt.
HBD, was jewel, had two radiators and more money in silicone to seal up the expansion chamber than a pipe would of cost. IT was a total sleeper for sure.
