Do any of you know what the Borla Atak axle back sounds like compared to a muffler delete? Is it a little bit quieter on the cold start? Does it get rid of the awful drone? I've seen people on here say that Borla doesn't drone, but many people also said the muffler delete doesn't drone when it definitely does.
Anyone heard both and can compare? People that installed the borla, did you see how it sounded with no muffler before you put the axle back on?

May want to look into a J-pipe/Helmholtz resonator. There's also Augers you can throw in too. Otehrwise the Atak is known not to drone if you have the money to blow.
