Q: I have a FMF TI Powercore exhaust with header and megabomb - it is too loud - how can i quiet it down to around 96dB???

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.

A: ^^^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.
