John,

Now that i've been driving for a month, definitely notice the power gain for sure. As far as the noise, not bothering yet at this point; a good set of ear plugs on the horizon for the longer trips though. I find the sweet spot at 2500 RPM to carry a conversation and be comfortable without plugs..

Overall, highly recommend them especially if you have some cam in the engine; sound is incredible and turns heads.

I can't thank Craig (aka Cobrakiwi) enough on this as he did an incredible job. In fact, I would reach out to him regarding your desire to switch.

Hope this helps a bit...
