So I deleted the muffler in front of the rear axle. I still have the resenator over the axle and everything else. Only thing different from mine to yours is I have that rear resonator and havnt gutted the cat yet. Think it will sound close if I gut the cat? Man that is the exact sound I am looking for. I see nooooo point in spending $1000-$2000 for a sound you can achieve like this. Damn that sounded great! 2017 5.3 by the way.
I have a 2012 with a 44 series flowmaster and I want to put headers on it and I really want to get rid of all three cats but atleast the third would help
