I installed yesterday. Took me most of the day by myself. Not too difficult. It took 4 hours to remove the OEM exhaust system (trying to keep the OEM parts to sale or if I ever want to go back to stock) and only about 2 hours to install the Dynomax exhaust system.
That OEM inverted bolt that was secured at the Y was a pain. I used about 3/4 a can of pb blaster removing the bolts and isolaters. Also cut an inch or so off 55428 towards the resonator to make the hangers fit in the stock isolators.
I like the sound thus far and has mininal drone. Ive read that things should "adjust" after a period of time.
Thanks for the pics that the OP's shared. That helped alot.
Per Flowmaster's specs I torqued all clamps at 80ft lbs because I couldnt find torque specs on Dynomax's website.
