Will this product work with the powercore 4 that goes on my klx 140L?

No. The FMF Powercore for your Kawasaki KLX140L would be considered a "Mini" Powercore. This Quiet Core insert would only work with the FMF Powercore Muffers for full-sized 250/450 motocross bikes.

Works with spark arrestor?
Does this insert work in addition to the spark arrestor on the powercore 4 or does the quiet insert replace the spark arrestor. If it does replace the spark arrestor, is there still a screen in it to prevent sparks?

The quiet core would replace the spark arrestor insert so there is really not a way to run them together in the Powercore 4 exhaust. I would have to recommend looking into the FMF Q4 exhaust if you needed a quieter exhaust with a spark arrestor as well.

Unfortunately that screw is not readily available for purchase through our books. For this specific item you can call FMF directly at 310-631-4363. The screw can also be obtained from a local hardware store. Its an m5x10 screw.

I have a FMF TI Powercore exhaust with header and megabomb - it is too loud - how can i quiet it down to around 96dB???
08 KLX450. I also have what looks like a FMF quiet core insert but have pulled the muffler apart and it will not fit. I can take a photo of the exhaust and the insert if you like but the insert looks the same as the pictures i see on all web pages.

^^^you may have bought the fmf quiet core for the ti4/factory4. it looks the same but has a different diameter. i have the insert installed on my 04 crf 250s powerbomb and factory 4 systme and it quieted it down substancially. i dont know the exact dB but it passes tech inspection for ecea hare scrambles, sooo....it works! they sell the quiet core for your exhaust, so it you want to spend the $25 its worth it.

no this is just a quiet insert, you would need to purchase the Ti Powercore spark arrester screen separately.

Mine actually did come with a spark arrestor screen in it. FMF may have updated it more recently to have one
