i just bought the 300ex t-4 silncer from rockymountain atv for $197 including shipping, it really improves power ('

'), but it's a little loud, i think i might buy the quiet core for when i trail ride.

I just installed my new T-4 on my 400 last week. I also rejeted the main jet. I noticed impressive gains in the mid and top and mild gains in the low end. The pipe is loud, but has a good sound to it. I also bought the quiet core insert, but it didn't seem to cut the sound down to much. Installation is easy and for $190 plus shipping from Rocky Mountain, it was a great deal.
