I have finished testing and developing my flash for the Graves cat back system on the zx4rr

The stock cat back weighs in at 9 lb 5 oz with the graves only weighing in at 2 lb 9 oz for a savings of 6 lb 12 oz

It idle it clipped off the DB meter at 70 db with a max volume of 111 DB during the run

the sound from the exhaust is aggressive without being overly loud and it runs extremely well when combined with my flash from idle to redline in all throttle positions and rpm's with no hesitations or flat spots 

Lets look at some dyno runs: 
​ first up is the stock bike(red)  vs  graves slip on with flash (blue)

Now lets look at the stock bike flashed( blue)  vs the graves slip on flash (red)

The graves cat back adds gains from idle to redline with a great sound and nice weight reduction.   A  very nice modification to the bike for those looking for some more sounds with the benefit of some more power and less weight.
