    I have been trying to decide what bike to purchase this spring and unless I find a KTM300EXC at a good price (I am talking new here guys and maybe a left over 02 model) I am going to go with the green DRZ (KLX400R). Ridden one or two and liked them a whole lot.

    The question I have is what is the best performance exhaust. Peak horsepower production does not matter to me. I am not going to be riding the bike with the motor reving over 8 grand all the time. I am talking real world low to mid range torque and horse power.

    Other question. Is the stock head pipe such a good head pipe than an aftermarket head pipe is basically a waste of money.

    Next question. Noise.
    Here are the brands I have seen. What I do not want is a noise level equal to a YZ426F. Nice tone but those babies are way too loud. I want good tone and depth but not obnoxious.

    FMF (Titainum and power core)
    Procircuit
    Bills
    White Bros.
    D&D
    DSP
    Yosh
    Big Gun.

    Comments, suggestions, opinions.

    Thanks

    I have a 2000E and my buddies have tried several pipes on their DRZs. Most are too loud. The stock pipe isn't bad but the only one I could recommend is the FMF Q. It produces a little more power than the stock and is quiet.

    In fact, several of my race buddies are putting the Qs on their WR250Fs.

    P.S. Love my DRZ! I have ridden the new KTM 450 and it is great but pricey. You can deal on DRZs.

    Thunder Alley! They build a mild steel pipe that has a complete "works" sytem look and performance gains not offered by typical designs. They typically use some form of oversized head pipe system depending on the bike it may be significantly larger or just slightly larger than stock. The mid-pipe dumps in to a true megaphone with a nice sized muffler section that keeps things toned down but louder than a stock DR or XR would be. You can choose to either have a standard end cap or a Krizman USFS spark arrestor for a whopping $45 extra. They also offer ceramic coating for those that like that look. I have a a friend that runs on on his 426 and everyone that has ridden the bike can't believe how much better his runs than bikes with WB, FMF, PC or Big Gun exhausts.

    If your stuck on a big brand pipe then Yosh is far and away the best. They design their pipes to provide an improvement or they won't market them.

    Curtis, as you know I have the Yosh "Off-Road". The reason I like it is:
    1) Spark Arrested
    2) TEC tips. You have 3 options in restriction with these:
    1) None
    2) Slightly restricted
    3) Moderately to very restricted
    with these options you can pick and choose the sound for the area in which you are riding that day.
    3) Yosh has more experience with the DRZ than anyone. They helped make the stock pipe for the bike.

    With the slightly restricted set up, the bike is fairly quiet and still has more power than an unrestricted Yosh RS-3 that I used to have, yet is smoother in power delivery(by my seat of the pants experience).

    I have yet to ride it completely open or completely restricted with the Off-Road pipe.

    drz exhaust

    I ride 00 drz (kicker), in the eastern US and Canada. I decided on a Pro Circuit T-4. It's alot lighter than stock. The biggest advantage is the power increase. This pipe really wakes up the DRZ. and w/ adjustable end caps, you can adjust your powerband where you want it. The noise is increased somewhat, but its hard to have both power and quiet on 4-stroke.

    Also, you really didn't say what kind of riding you do. and how fast you like to go.

    POWER !!!

    ThumperRDing, I have a PRO - CIRCUIT T- 4 EXHAUST SYSTEM. It has a SPARK ARRESTER. I have the optional quiet insert. I love this system. With the uncorked system it is loud and very powerful. If noise is not a issue you can run it uncorked. If I am racing a ENDURO that is the way I would run it. But for general Trail Riding or Dual Sporting I put the insert in and it is quiet. You only loose a little power with the insert in. If you run the tight woods, I would drop the front counter shaft sprocket down to a 13 tooth. And if you put a new Exhaust system on , you should rejet to 172 main, 48 pilot, drop the clip one on the needle and go out 1 1/2 to 2 out on the air screw. Take out the snorkle on top of the air box. This is my set-up and I run it all year long, summer thru winter. Good luck, SIGGY
