Has anybody put an MBRP Particulate Filter Back Exhaust on a 4th Gen and put some miles on loaded and unloaded? I have a 2012 2500 and am considering the MBRP T409 SS exhaust shown in Geno's catalog for the 2010-2013 HD's. I am interested in your feedback on sound, any drone problem (if yes when/what rpm), pros/cons over stock based on your experience, ease of install (I put a Hogg exhaust on my 2003 years ago and it was not difficult.) I am not looking for any HP/Torque gain or any performance boost, I know that won't happen, I am really just looking for a little more aggressive sound, emphasis on slight, nothing crazy, and I also like the bigger rolled tip (but I could add simply add a rolled tip to those to the stock exhaust.) I appreciate you sharing any experience you may have with this set up.
