I'm getting ready to do this mod- 07 3.0i with 3 stage manifold conversion.
I can't find a consensus on the correct muffler to use. The OP and video show a 12468 model, yet others are stating that the 12468 is too large and the 11385 is more suitable.

Can anyone else confirm which is the better fit, and if there is sound differences between the two?
