How is that able to pass DOT emission inspections? I assume you get enough coming out the tail to meet test but isn't this (morally) wrong to the smallest degree? I'm not judging, i read a post where an inspector saw it and didn't say anything. I agree the sound is great but it seems to me it's similar to when i was VERY young the older boys would put a hole in the muffler to get a throatier sound.

Mufflers don't really affect emissions, that's primarily the cats' job.

We don't have emission inspections here in Alabama. But yeah, It's pretty much like having a leak in the exhaust pipe.

I don't have a sound clip but above is a thread that talks about the vents and has a clip of the sound after the vent install.
