KSE Posted April 1, 2010 I have a XR650L and I want to jet obviously, and then exhaust... I want it to be louder than stock, but not ridiculous. Tunable would be great, or at least a silencer insert, and of course a spark arrestor. Any one have any suggestions to what kind to get? Share this post Link to post Share on other sites
kellymac530 Posted April 1, 2010 unbolt the exhaust, roll the bike out from under the exhaust and roll any other bike under the exhaust...then throw the exhaust away and your whole problem will be fixed......👍 just hassleing you hahaha. the fmf q4 is a great muffler, a big gun with the quiet pack is also good. on the xr bikes i used to see alot of supertraps or IMS e series with the discs but i have never been a fan Share this post Link to post Share on other sites
craig hammon Posted April 1, 2010 I had the FMF, it lasted about 10,000 miles. When it fell apart, I ground the welds down on the inside of the stock header, to increase the flow, then I removed the insert from the tip of the muffler. It seems to be the same, power. It weighs more but since I ride to the beach in shorts, and sometimes in a wetsuit, I like having the heat shield. Craig. Share this post Link to post Share on other sites

2ksilverbullet Posted April 1, 2010 I just added a Q4 to my XRL last week. It doesn't seem much louder than stock, sound is much better, and the performance is actually felt in the seat. I had dave's mods done with the stock pipe originally... Share this post Link to post Share on other sites

EXxrldtgnow300dtg My Ride Posted August 8, 2010 I just added a Q4 to my XRL last week. It doesn't seem much louder than stock, sound is much better, and the performance is actually felt in the seat. I had dave's mods done with the stock pipe originally... The Q4 is a great sounding/performing silencer, it has a much nicer tone than the stock and barks with a twist of the throttle. You will feel an increase in the mid range, but nothing down low. I had my XRL for sale and whilst selling it had a guy offer me money for some of the aftermarket goodies, one being the Q4. I had been riding the XRL since then til Friday when I sold it and I have to tell you, I really missed that Q4 sound and mid range power. I don't like the whsitling VW impression the stocker makes.

Besus72 Posted August 8, 2010 I agree with the q4 not too loud and sounds great too. Its way better than the stocker. I still have stock headpipe also. Share this post Link to post Share on other sites

Yeah, keep that stock headpipe, don't get some other head pipe until you've done more serious interior work on the motor. You're wasting your money otherwise.
