I would like to know also.I have read all through these forums and it does not seem like i can find a straight answer as to what pipe has worked the best on the Predator.I see alot of people use the white bros and the hmf slip-ons.Out of those two what makes better power?Surely by now some of you with these pipes have raced others with other pipes.Lets hear how it went.
The difference made by these pipes will be so very, VERY small that it will always end with whoever is the better rider. Plus, nobody has done a true comparison test with dyno results yet, and odds are nobody will anytime soon.
I think your best bet is to go with whichever one you like the best, which includes price, sound, looks, etc.
I've heard stories of the HMF pipes blowing cores on other quads (not Predators) and don't really want to even try one. I do recall from the dyno/comparison tests on other quads that the CT and White Brothers pipes are always at the top for peak horsepower, so I'm happy with my WB pipe.
If I were to get a full system, I would probably get the Trinty, but I don't see the point in spending $500 on a system when it won't do any good over the WB pipe. Trinity is known for doctoring their dyno numbers so I don't believe for a second what they publish on their site.
I don't have any info on the WB pipe, however on our two Preds, I have put the full Big Gun system on each one. They look great, sound super and run much better than stock for sure. Still waiting for cool weather to return so we can run the dunes this fall ... that will give us a chance to compare this setup with everything else out there .. after that I can give you a good idea how things really perform.
I love the FMF TI4 I have on my pred, kinda loud but lots of power and looks great (sea profile w/spark arrestor end cap). Rocky Mountain ATV has what they call a power package for 389.00 I think. Its the TI4 with steel mid pipe, K&N filter/charger kit, jet kit, (130-190mj I think) and outerwear prefilter. I have read several articles in magazines about the header, the mags claim that the stock header is just as good as aftermarket (didnt see any dyno comparisons nor a machine with a full fmf system to compare yet)
I decided to buy the White Bros.Just went and got it and some extra disks.Also bought drop-in KandN Filter and filtered airvents for the airbox.The dealer told me to drill out like 5 small holes in the back of the airbox and put them in there.Does this sound right?Will i need to install a jet kit with this setup?Thanks
I bought the slip on WB and pulled the discs out. Plenty loud and the quad runs perfect for my harescrambles. I heard that I might lose some low end by pulling out the discs, but haven't had any problems with it. Other than that, I run the bike stock, even still using the paper filters that they come with. I get about three races out of a filter, but race in muddy conditions alot. Any feedback from anyone?
I'm Running the Ti4 Pipe with the Titanium mid, with standard 2inch output. I love it, but it is real loud. i imagine it has no back pressure set up like that either, but it seems to work for me, although i notice i am always on the rev limiter now - James
My FMF Ti4 is on it's way from RockyMountainAtv.com along with the K&N filter and Uni-Vents. I can't wait. And yes the White Bros pipe is available as a White Bros E series at rockymountainatv.com for $218.00 and no shipping charges.
