Greetings. I am looking at buying a new muffler for my 04 wr450. a lot of my riding is on the road,(work & back). The GYT-R muffler is just to bloody loud, fmf Q pipe has no or little performance gain,( local dealers words, not mine.) They also have DEP mufflers. Same price as all the others but has good performance gain. Also is not to loud. Any advice? I still do quite a lot of dirt riding, just need some help.Cheers.
