I have the ct national mid, Its a great pipe. good bottom, super strong midrange and decent top end. it doesn't have top end like I would like for dune usage, but is a great pipe for play,trails, MX or woods IMHO.
For trail riding it would be hard to beat in my opinion. Im currently looking into other pipes for more top end, but will definitely keep the ct for woods and trails. I can say from experience thats its good from a stock displacement to a 350.
