I recently installed the Cobra el Diablo 2-1 exhaust along with kurykan velociraptor air cleaner and tuned it with FP3. The installation was not that hard it took me about 5 hours to do it. That’s because of my lack of mechanical skills and availability of sufficient tools. The AC took literally 15 minutes to put on and FP3 had a map for the setup.
The exhaust is amazing so far. Tons of midrange torque and faster response. I have to say that it’s on the loud side. I hope my neighbors don’t get mad.
The only previous mod was the Biltwell scrambler 4” handle bars.
