I have 13 RT auto, I want to remove the resonators and possibly the mufflers. I was quoted at $80.00 to remove the resonators and $140.00 for the mufflers and resonators. I have an auto, and I want to be sure it'll sound nice. All the youtube videos show manuals. If I do get the mufflers removed should I replace them with super 10's? or Cherry bomb mufflers? I want a nice rumble and I just need a few suggestions with what I should do for that, since it is an auto I know I'll have drone but I don't mind. I just want the exhaust note to sound perfect. I was also wondering, the exhaust pipe is 2 1/4 ? 2.5 for the manuals? Thanks you guys!
