Cookba I will have to look into that setup. Is there a catback that sounds mean with no rasp? I want it loud but not obnoxious. But unfortunately I don't know anyone with a fbody around me. I posted in the local section too so I can meet people to hear setups in person

True duals. Most y-pipe set ups get raspy with longtubes and no cats.

Magnaflow doesn't really get raspy. It sounds mean at WOT. Not really that loud through the rest of the RPM's though. It has a nice deep tone...

Yes it is. The same guy used to make the catback for GMMG.

People tell me my car is wicked loud all the time. Then, I open the cutout and show them what loud really is. lol

I have the GMMG with a catted Y and I really like it. Much quieter than the dumped duals I did have. No more smelling like fuel when I get out of the car, and its loud when I want it, quiet when cruising.
