a friend of mine has one on his kfx and you can tell. I like it though it has a strong tone to it.

them t-4's are loud with the damn quiet cores in there... get the full system and take the core out, that'll give you a head ache:devil:

to bad they cost to damn much though or i'd buy one

I used to have a t4 on my 400ex and it wasnt bad at all. I have an hmf on my yfz with out the quiet core and it aint too bad.
