Mine actually arrived from Dennis Kirk yesterday! Cobra Lies!
Of course it barely got into the 30s here today and my "garage" is my 6x10 race trailer. Maybe I'll poke at it tomorrow. I'm excited to see how it sounds and performs.

I had a 25 minute session on the gluteus dynomometer this morning and have this to report: improved off-idle response, improved throttle response across the rpm range, a bump up in torque across the range, with a strong rise occurring ~3700 rpm with a continuous rise up to 5.5krpm, roll-on in 4th gear from 45 mph to 75 mph got me up to speed significantly faster than stock (duh!). I have an idea of what I want my torque curve to look like, and can hopefully get some dyno time soon to see where I stand.
report is for stock internals, only changing over to SE stage 1 AC, El Diablo 2-1, and PC-V running Dyno-jet supplied map named "2017 XL1200 RSD Tracker 2-1 full exhaust Screamin' Eagle air filter"
I've been in communication with D from DK custom products about installation and tuning of the TTIs as well.

I'm down with trying them out. I definitely have a flat spot from 2.5k-3.7krpm I'd like to get worked out. That may simply be fueling; we'll get that diagnosed at the dyno appointment. Also, I'm going to pull two screws out of the end of the muffler and see what the end cap and internals are all about and of course get measurements and pics for a possible TTI addition.
As for sound, "El Diablo" is an appropriate name. It sounds like it means business, like hide your wife and kids business. But text is lame, I'll shoot for some mp3 on Saturday.
