I recently had a powercore put on my 400 ex and i guess i'm happy with it but honestly how does this pipe rate?

I don't know it "rates" but when I ran one on my 400 I didn't care for it:o

i have one and i like it. i love the sound nice and throaty but not to loud to where its anoughing. my friend with his old 300ex had an HMF, mine was louder at idle but as we went threw the RPMS his was just crazy. i liked the bottom end power. not that great on top end but unless u ride top end a lot, why put power where your not going to use it
