Best aftermarket pipa

Looking for the best, loudest, most performance giving pipe for an 04 YZ450F, I do a lot of desert riding :cry:

You may want to do a search here on TT yourself...I'm sure there will be a big pissin' match over this subject. At least that's what I've seen happen in the past. :cry: The only pipe other than stock I've tried is a White Bros 'E' series....only to meet the Noise level and to have a Spark Arrestor here in Lovely California. I sure miss riding in Nevada :cry: I did notice a little loss in power with the White Bros 'E' series, but it wasn't that bad. :cry:

Thanks for the info, thats what I have on my Raptor and that made a big difference, I guess Ill do a search :cry:

I have a Jardine system and do lots of sand riding its an awesome system it had the highest hp ratings in the mxa tests.


I have the Yoshimura RC-3 Ti set up and really enjoy the quiet idle and loud rap rap when you are on the pipe. The fit and finish have lasted for over a year now. The pipe polishes up nice after every run too. You can feel the power brotha! :cry:

If loud is what you are looking for then get a White Brothers R-4 Shorty pipe. About as loud as you can get without running muffler-less.

I've always liked FMF and White Brother's.

FMF Titanium Series

FMF Factory 4 :cry:

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I could use some feedback, My son is getting into off road riding so I have starting getting back into it as well.  We mostly do trail riding but did some MX track riding last year and he loved it andso did I.  I have a 2003 TTR 225, it's nice that it has an electric start but the suspension is too soft and it doesn't have enough power for my liking.  When I was riding the MX track I was having issues bottoming out on the larger jumps.  I want to change to a more off-road capable bike.   I won't ride it much and don't want to spend a lot of money, I think I prefer a 2 stroke, when I was younger, in 1990, I raced an 89 RM250 and loved it.  I am looking at a 96 RMX 250  and a 98 YZ400F, both bikes look to be in good condition and around a thousand dollars.  I like the RMX because I think kicking a 2 stroke 250 should be easier than a 4 stroke 400 and the simplicity of the 2 stroke engine.  The 400 sounds good because of the low end torque I assume it has but the cost of rebuilding the 4 stroke if needed worries me and I have heard they are hard to start. Should the RMX be decent for an occasional trip to an MX park?  Any thoughts on these two bikes?

      Brand new, still in the packaging Lexx end cap fits the stock muffler of 2006 & 2007 YZ450f and 06-13 YZ250f. Comes with a forest service approved spark arrestor and two different size tips. Don't spend hundreds of dollars on a slip on, this tip can be quiet and forest legal or loud and make power! Also a note for WR450 guys: get this tip and find a used 06/07 YZ muffler, fits directly on 09-15 WR450. $80 shipped free to the lower 48. PM, call or text 406-223-8789

      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.
