Exhaust help

[FrostyNothing]

I messaged the guy from top speed pro 1 and this is what he said when I asked about the difference in the mufflers between the M2 and their brand is that
Their exhaust are made of 16 Gauge thick piping with perforated straight through chamber with fiberglass sheet and stainless steel wool packings to reduce the drone level compared to M2 exhausts.

So idk

I will probably order their exhaust as what he said makes sense. They also seem to be the bestquality and seems they are pretty popular company. I would also be ordering from an American company and not some Chinese one.
