i have a 2004 yamah raptor with a power bomb header and was looking in to getting the q or the fmf power core and i was wondering how the power was on the power core and if n e one new if the power bomb header will met up with n e other silincers

 

Well, i have a powercore muffler on my LT250R. But its an old 2-stroke , i dont think they make them for rappy's do they??

I have FMF high flow header, with a PowerCore 4 silencer on my 01 Rappy. No complaints at all.

 

I think FMF has a fairly new pipe out for the 4 bangers. It's called the Factory 4 and is souposed to be awsome. Not sure if it is aviable for the rappy, but I've seen it on a couple yfz's and it looked and sounded awsome.

 

I had the Q muffler. While it improved power over stock, I still wanted more at times. The FMF Titanuim 4 I have now offers a little more versatility, installing the quiet core when I want to keep the db levels down, or using the 2" cap when I'm at the dunes.
BTW, I'll sell that FMF Q muffler for $100.00 (shipped), if anyone is interested.
