Two Brother Exhaust with P1 insert
I have my RT flashed with the 8,600 rpm rev limit. I use Lamont's cat delete with the sound insert, Two brothers Exhaust with the P1 performance tip. My bike pulls so hard after 5,000 rpm that I can't believe it's the same bike. Check out this video of my test RT bike. https://monsterfuelinjection.com/spyder/ It show my RT going from 0 to 90 mph in about 10 seconds as it still has the stock speed limits in place.
Notice how one of the three speed runs the nanny didn't kick in, and my front end unloads and floats. Also notice at the end of the video for the roll on test where I say and show 5,000 rpm to 7,000 rpm roll on. I'm accelerating from 48 mph to 88 mph in 8 seconds shifting at only 7,000 rpm which is well short of peak power at 8,600 rpm. This is where the Stage One Monster flash really shines. My pathetic stock RT times were only getting to less than 70 mph with the same test. Blows me away that a flash gets that much performance.

A Two Bros exhaust, in comparison, registered about .5 psi under the same conditions. If the ECU can be mapped to accommodate that change, that would be great.
