ok, someone please set me straight! ive heard about using a ttr225 header pipe with a FMF powercore 4 muffler for a tw200. this sounds good with me cause i like the sound of the brand FMF. but how do i do it? on tuesday ill go and grab a 2011 tw200 and would like to know what are the nessasery parts to have. will it bolt right up in the stock locations? if the tw200 is a 2011 what year ttr225 header should i get? ive only been able to find a 2011 ttr230.also would i need any special exhaust gaskets or funky springs of some sort? as you can tell i have many questions about this topic and need much help. this is my first TW and i want to make it right the first time. thanks a bunch!
