I have that same Magnaflow round muffler on my stock exhaust. I installed it for my ORP, but right now I have the stock cat on and all I can hear is the engine at WOT.
Check out powerflexusa.com for front exhaust hangers, #005 for the front. With that muffler the hangers will be in sag city after awhile.
EAP with 1/3 of the cold weather package. No block heater or TCS.
