I think it's amazing that the duals weigh less than the stock single!

 

yeah, that is amazing......... LOL!!!!!!!!!!!

 

I would like to see the DYNO graph on these pipes 13 hp might not be that much depending on what RPM they hit +13
Just using CT pipe as an example CT hit 7 HP at 3000 rmp's and 32 hp at 8500 rpm's ( YES 32 HP ) those gains are measured above the stock base line huge difference in the power curve . Even yamaha GYT-r Dyno chart shows huge HP increase in the top end . Would like to see a dyno sheet on these pipes .
Headers usally make more Hp on multi cyl engines than single pipes do but were not talking multi cyl were talking single
Hey if any of you want to buy me one I try it and let you know if it works I PROMISE
