09 with V&H two into one. The stock specs say 114 torque. (How reliable are those numbers?) I didn't get a before and after. I feel a little increase in power but not much. Sounds a helluva alot better though.

 

Hi, i added a set of big radius two into two by v and h when i bought my 09 cvo. when i had it serviced at 1000 miles i had it dynoed with a screaming eagle race tuner. It sounds great but as far as power. Just stock with the pipes was plenty. They say it will run cooler now. Dont know if spending that kind of money on the tuner was nessasary. Here is my bike and dyno sheet. max torque 110.21 max hp 87.33
