I think this combination will quiet down the drone to an almost nonexistent amount.
And By X pipe I mean replacing it with the Magnaflow 10791 Part. The opening is at least a half an inch greater than the oem one, which is seemingly crushed. The guy who owns the muffler shop by me is a relative of the Hendricks Motorsports team and he says while the stock set up is great, the X pipe is shitty. It's a simply 60 dollar fix that will hopefully clear it all out. I've invested only $375 overall in getting the secondary cats taken out and replaced with straight pipes, and the mufflers bought/installed.
