Looking at Full exhaust systems and really like the brocks system. I have seen great success woth them on the 1000's but will that apply to us 600's and 750's? Seems alot of drag racers use Brock exhaust systems and have really good ET's with them!

So the question is, who is running them?

What kind of power can be gained with a full exhaust?

And how much weight will be dropped? The full exhaust weighs right at 9lbs.. What does the stock muffler/cat/header weight?

I have alien head on mine ran it on 600 motor and on it now with the 750 swap. They(brocks) tend to make really good power on whatever bike there put on. I know Joely750 has one on his 750 and his bike stock motor is flying and i think sypdigtconv149 running one too on his 750. Weight savings i guesstimate about 12-15 pounds over stock exhaust. Mostly from not having the catalitic converter box thing its heavy i estimate that back half of the exhaust on stock bike is 20 pounds alone

I know I'd love to have one. Just the $$$ is the question. Awesome company though.

Compared to other full systems I've seen around 1300-1600 these are actually cheap I've seen them for under 1100.

It sais the full system weighs 9lbs, now I know the Stock muffler and cat weighs 24-25lbs so that alone is 21lb savings but what does the stock manifold weight? I read a few websites and one says 30lb savings anon sais 40 lb savings.

Another question I have is weight to power ratio. I know on a car 100 pounds is roughly 1mph and 1 tenth which is around 10hp gain. This is just average, different track conditions etc etc can affect everything.

So on a 600 if the exhaust gains you 12rwhp and you drop 35-40lbs where does that put the bike MPH wise if I was trapping let's say 128 before? It's hard to go by ET cause each visit to the track the 60 foot changes and the driver gets better.

Finally bolted everything up 7" over,520 conversion -1 +2 and this thing feels like a beast! Definitely need a shinko u soft.

Can i find this exhaust system in europe??

from stock exhaust expect to add 3 to 4 mph not sure about your weights my opinion is the alien head system will save you roughly 20 pounds on that 600. And give you a nice gain in hp estimate roughly 5 percent more power when tuned from what you have now.
if ya runnin 128 now with stock exhaust figure on 131 132 neighborhood with the alien head system i personally picked up about 2 mph going from a m4 gp slip on
