Anybody heard of these and what do you think?

They've been around for a while, my brother had a 4" Mufflex that exited the car on the left side years ago on his Z. Probably other models out there now. Don't seem to be that popular anymore.

Yeah I haven't seen much of them but a friend of mine had the 3 1/2" on his blown and cammed camaro lt1. I swear it sounded like a big block. It was tough sounding.

Don't know about flow - but probably some sound clips on ls1sounds.com

Yes there are sound clips at LS1 sounds .com.

This is probably the highest flowing F-body specific System.
Problem is that the 4" system may be overkill for stock or mildly modified cars.
The 3.5" system may be a better choice.
