El Dorado System is a bit Hit at my house

Ride: stock 2009 Road King 15K miles. I bought used 3 months ago. Problem: 1) can't hear RPM's, 2) passenger Right foot excessive heat from CAT 3) Needs to be a CARB compliant solution to maintain ESP. (Yes I'm Kalifornicated) Solution Options: I could find only 2 systems CARB compliant. 1) competitor Power Duals but has CAT in same place. 2) The El Dorado MK 45 system from S&S. Removed Stock and installed the El Dorado in about 4 hours. Looks awesome, very nice quality, sound is louder than stock but not obnoxious at all with a deeper tone. RPM's can be heard at any speed. I feel like I'm on a Harley now. Heat problem all gone. After a recent 2 up ride I asked her about it and she had totally forgotten about the previous problem. No tune has been done as I mentioned everything else is stock. I can not notice any loss of power or torque. Very happy with this system.
