Pics of your Exhaust!

I've been searching for about 30 minutes on here and google and whatever. I'm stuck between White brothers E2 exhaust and the Dr.D. I can't decide and hoping I can make my decision visually and I figure most top end exhaust are about the same performance gains. I prefer to see the two I listed but open to others, I searched and can't find a thread dedicated to photos of pipes on a 2006 YZ450F or whatever so I figured we could start one? :censored:

Supertrapp is building a new exhaust designed by legendary flattrack tuner Bill Werner for the 06/07 YZ 450's. I'll have the prototype system to dyno with next week. All I have to compare it to is the stock 07 pipe. But by next week i'll have dyno sheets of an 07 450 with Hot Cams and this pipe. I'll dyno with anything else for comparison if you want to ship me the pipe.



that thing looks LOUD!!!

Dr. D on an '07


It's actually been designed for the sound rules that haven't yet been implemented for dirttrack and are coming, most likely in 2008. I don't have a db reading, but i've been told that it's pretty quiet.

Not on your list, but a greaat pipe with a great warranty, for a great price, plus it loos great; doesn't stick out like a soar thumb.:censored:





Another one not on your list is the FMF factory 4.1.I have the full system with the megabomb but I like the stock header for indoors better.This is the carbon muffler.



Yes I know their not the best pics but you can get an idea.

But by next week i'll have dyno sheets of an 07 450 with Hot Cams and this pipe.

It would be much more informative to see a direct comparison of a stock bike and a stock engine with the ST Pipe added. The pipe may well be optimized for use with a different set of cams, but showing the results of changing two things at once doesn't highlight the individual benefits of either.

Heres mine. GYTR with header.


WB Aluminum Pro2 system...much better than the E2



That's a pretty trick lookin' pipe

look at his garage, his got his frame powder coated bright orange :censored:

How bout an FMF Q2??


Not only is my pick trick looking, it's an awesome piece of metal too. It's quiet but throaty like a 450, and really woke up the power.

bitchin pictures. I think I will go with the White bros E2 slip-on spark arrestor, considering everyone seems to like the flow of the stock header the way it is

i just order the Dr.D pipe for my 06 yz 450 ill post pic when it comes

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator work? Anything else I should know? Any help would be appreciated. Thank you.

      Alright so I’m new to the site so maybe this question has already been asked. I have a 2002 Yz426f and I want a new exhaust, it has the stock header and silencer and sounds amazing but I’d like a little more from it, I know I want the fmf power bomb header and am kind of undecided on the silencer, I see on fmf’s website that their silencer will add low end and slightly take from top end and the other way around but I’m looking for increases throughout rpm range. I do a lot of trail, hill climbs, jumps, and wheelies so kind of need good performance everywhere in the rpms. My question is what silencer I should get and the jetting I should get for the carb. Thanks

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!

      Alright guys, my 04 YZ450f runs fine minus some slight backfires when decelerating (need to adjust fuel screw). The other day when I was done checking my valve clearances I changed the oil and filter and put the bike back on the stand, kicked it a few times without the ignition coil in to get some oil flowing got off and noticed a little drip spot on the ground, it was no bigger than a dime so I thought nothing of it. Started the bike with no issues took it for a quick 10-15 min ride, came back to the garage to find out my whole case was soaked with oil and it started pooling in the low spots on the clutch basket side. I cleaned all the oil off and took it out again for 5 mins to try and see where it was coming from, here are my three possible places but nothing directly leads me to believe it’s any of the three either.
      1. Decompression plug area
      2.  Valve cover gasket leak (not really sure because the amount of oil leaking Looks to be a large amount
      3. Oil tank (bad weld or cracked weld somewhere
      what are you guys thinking?
