I am not one to chase HP numbers but I have been thinking about making two small changes on my Breakout.
My bike came from the dealer with V&H big radius 2-2 pipes that I know are more for looks and sound than efficiency. Not to mention the higher treble exhaust note gets old at highway speeds. To that end I am thinking of upgrading to a D&D low cat. The wrapped baffle should sound a little better to my ears than the strictly louvered baffle of the bobcat. HP is the same according to D&D.
Second I am thinking of swapping out the stock 255 cams for the zippers redshift 587 cams. From the little I have read it should carry the hp and torque a little further along the rpm range while not beating the valve train to death like the 255s.
I do realize the valve springs are also part of the problem but not looking to go down that path yet to keep costs down (I know, funny right). Currently have S&S premium lifters that I had put in at my 5k service. Likely do those again with the new cams.
Does it sound like these two changes will play nice together?
