MBRP !!!! Gain of about 3-5 HP and you save about 12 LBS and it is alot cheaper than the ones you mentioned, and they sound good !!!!

I have schmidt bros. stuff and am very happy. Clutch kit has a sweet spot from 11000rpm's on up. The single pipe is very nice. It sounds great ( not blatty), looks good, saves 10 pounds, and adds 4hp. Call chris at schmidt bros. He will answer any questions.

as far as i know excell is the only pipe that has been individually tested and confirmed for the HP numbers. i may be wrong but i havent heard of any other then excell being tested. Companies usually exaggerate their HP numbers or they have to be used with other of their products to get the numbers.
just look at silencers for yamaha 2 strokes. all companies claim and increase but they have proven that in most cases u actually loses a HP or 2. but u lose weight and they sound good so it seams like its has more power.
