Fabspeed Bypass Question

Can anyone tell me if the inside of the resonator portion of the bypass is perforated or smooth?

TIA

It's just a smooth-walled tube. You could roll a golf ball though it.

Yes you can roll a golf ball thru it, but mine's not a solid wall pipe. It is indeed perforated somewhat like the inside of this glasspack

The factory pre-muffler does have a perforated section in it. I suppose it does muffle a bit. The Fabspeed is just a smooth pipe like SPin City remarked.

I guess i'm going to have to take a picture of mine to prove the perforated section exists............
