Hello Taige / Beau,
I want a full system for my 09R1, it's between Graves and the Akra Evo. How does Graves compare to the Akra?
Both companies build quality crafted products and Im glad to see that you are choosing between the best of the best. Spend the money and buy quality product and you are sure not to regret it. Buy cheap .... not so sure.
1st- and most important to me is power/torque and how it is delivered.
Again both systems make great power, and you cannot get perfect comparisons unless you do back to back dyno runs with each systems but our systems have shown a little higher results in most testing that I have seen or heard . Even more important is that they are very consistant and linear with no significant dips and valleys in the delivery. This takes a lot of design time , testing and tuning to eliminate these dips however they make a big difference when riding. Consistancy in power is very imporatant and I believe we have developed the most consistant power delivery in addition to excellent power.
2nd- weight savings
Our exhaust systems are the lightest in the industry. Our silencers have titanium entrance, exit caps and even the inner cores are Titanium.
For example our full Titanium High mounts systems for the 2009 R1 weigh in at a total of 11 lbs. That is piping, dual silencers and a all hardware. It is exactly half of the weight of the stock system and is the lightest that I have found. Removing weight is like gaining horsepower plus it significantly helps in the bikes handling.
3rd- Aesthetics and Sound
This is a tough one because everyone has there own opinion on this. What I can say is we have an exclusive way of packing our silencers which creates an extremely deep exhaust note. I personally do not like a high pitch, can sound to my exhaust. Not saying that Akras sound high pitch but I have heard many systems and nothing so far has given the deep exhaust pitch that ours does.
Aesthetics..........Both systems are good quality and nicely made but I like the fact that our silencers are a little smaller on the diameter and tuck away nicely under the tail. For me I like a simple no clutter bike and ours seems to offer that a little better.
Like I said you are choosing between 2 well made systems I just think we have the edge on power, weight, and sound. The looks is very personal so you will have to make that choice.
If you have any questions feel free to ask me. Thanks, taige
