I've tried numerous setups on my Z ... some had a lot of drone, some had minimal drone but only 2 systems had NO drone: OEM and Corsas. I'm currently running a setup very similar to Bob's except that the catback I'm using is a 96 LT4. When Marc had my car for porting/dyno tuning he did back to back dynos with the cutouts open/closed ... the OEM mufflers keep everything quiet w/no drone but with a cost of 15HP at the wheels. With the cutouts fully open the exhaust is LOUD and there's enough drone to make my ears hurt. The Corsas are also very LOUD, especially w/out cats, but I never detected any drone when I ran Corsas, headers, no cats.
Interesting .... Thanks for commenting.
