FMF Q Stealth Spark Arrestor Silencer

FMF Q Stealth Spark Arrestor Silencer

Pooter - Chattanooga, TN
4 out of 5 stars
What you would expect from FMF. "Replaced the OEM muffler on my 09 ktm 250 xc w with the Q stealth. Fast shipping from MotoSport as usual. When I opened the box I was surprised at how big this muffler is. It's almost as big as some 4T mufflers! It's about the same weight as stock though. It mounted up easily with no alignment problems at all. It's a little more quiet than stock especially at lower RPM's. I didn't change the jetting and even with the spark arrestor installed it seems to give a little better throttle response. It's not night and day difference but overall I'm happy with this muffler."

Read the NOTES in the description "Don't be the same idiot I was. Measure your exhaust diameter BEFORE ordering. I didn't, and surprise surprise, it didn't fit my bike. All the information is there, don't be that guy (this guy). Motosport took care of me very well with the replacement part as always. Thanks guys!"
