2005 crf450r muffler.

aftermarket: MRD

I agree, the '05 R muffler is great and you can pick 'em up really cheap on ebay. If you want something a little quieter though, there are some great offers on the FMF Q4. Not quite so powerful but much easier on the ears.


MRD ProComp with quiet insert is pretty sweet. I'm using it these days since I keep blowing the spark arrestor inserts out and it serves as a sparky to.

The stock one is not bad. It's the header that will give more bang for the buck.

i have the fmf powerbomb with the fmf factory4.1 carbon fiber pipe.. its awesome.. Id even go with the megabomb header if i were you..

If you care about decibel levels then the FMF Q series is the way to go.

I have the Dr. D aluminum/stainless full system and love it. A little pricey but well worth it. I don't notice it being excessively loud, nor do my friends who have no choice but to ride behind me. Its rated at 96 dbs

Leo Vince works well, powerfull and quiet but Titanium one means to buy header too...

I have a Yosh full system that looks decent, is quiet, and is US Forest-approved as a spark arrester.

It is ridiculously expensive, though. It was already on the bike when I got it.

      Anyone having or had problems with the starter not turning over easily on the 450X???
      I have read about this problem on CRF's ONLY and not seen anyone come up with a fix.
      Problem being is that you think there is a problem with the battery, when infact the battery is OK. When you have a good fully charged battery in the bike and press the e-start, it turns over very slowly.
      I have checked the electrical circuit and it seems OK. I am wondering if it might be the starter itself - any suggestions?????

      I've studied the Jetting sticky's but still have a number of questions:
      I bought my '06 a couple of years ago and had a smog block-off kit installed and the pilot jet was upsized to a 48 and the air box opened up top only. The bike has appeared to run a little lean at times and got hot on a couple of occasions in elevation and on one other occasion. I'm looking at upping the main jet to either a 165 or 170 to help with the possible lean condition. The bike currently has a 142 main jet in it which I believe is the stock size. It looks like the most widely used Needle Jets are the JD Red, but it doesn't look like they are sold separately, is this correct?
      I was going to also get a 45 pilot to have options for further tuning. My assumption is that every bike is a little different and that where you ride is going to have a lot to do with jetting. We ride mostly, mojave desert, baja, and southern Utah with elevations from sea level to 9,000 feet but the higher elevations are generally for a short period as we generally continue through the peaks and head back down.
      I'm looking to convert from a stock exhaust to possibly an FMF Q4. I want something a little throatier but not overly loud and will provide a balanced flow of intake/exhaust.
      So can I get the JD Red Needle Jet by itself or can I get by using the stock and move the clip and be just as happy. I'm just looking to enhance overall performance of the engine and maintain reliability.
