I got the idea from my ZL1 that when had aftermarket headers added, it was extremely loud and the MF R X pipe made a huge difference.
I will follow up with more videos but here are some comparisons.
In cabin noise is practically gone unless WOT and it's still very quiet and the noise is behind you rather than inside the cabin resonating. It sounds so much quieter than stock while cruising yet outside the car still sounds beastly. There is practically no drone compare do before. The noise now is much more deeper and refined compared to any other system I've heard. Hard to explain.
PN Magnaflow 11386 Stainless Steel 2.5" Oval Muffler - Fabrication had to be done to go 3" OEM piping to 2.5" and back out or use a 2.5 to 3" adapter. So far no performance issues.

Bringing this thread back since after reading this sounds like a great idea ...
I found this part :
MagnaFlow Performance Mufflers 12469
Which is the same resonated X pipe as the OP except that in/out are also 3" instead of 2.5" , would this be a better fit ? Sound wise ?? Any comments /advice will be appreciated...
