Well, after some miles it is noticeably quieter both overall and the drone, but I as Derf pointed out, I still have some drone, just a different toned down variety. I've got a hard plastic sounding buzz in my passenger side I'm hoping to find, can't tell if it's the glovebox area or the door, but the solution to it all seems the same for now....bury your right foot, listen to that V-8 get up in the R's, smile, rinse and repeat......

Thanks for all the advice!

Default Muffs

Want great sound with ZERO drone? CORSA. Not cheap, but worth every dime.

Default Droning along....

I'm still a bit confused. The volume in db of my exhaust has diminished, as has the drone. I am pleased with the overall volume and note, but the drone while lessened, remains an annoyance.

When I had the most recent work, he swapped the H-pipe for an X-pipe and installed what I think he said were Magnaflow 40's?( I now see that they must be "Flowmaster 40's, not Magnaflow), not sure but he indicated they are chambered mufflers. I'd really like to get rid of the drone. The most recent poster noted that the Corsa has "zero" drone. Another posted noted "all" aftermarket catbacks would have some drone. Also noted was that my 2010 had no resonators. I've ordered a shop manual and will see what exactly the stock set up looked like.

I guess my questions are, do I need to go back to stock to get rid of all the "drone" (really all between 1500-2000 RPM)? Is the x-pipe contributing to the drone? Will I find stock exhaust "take-offs" or would I need to roll the calendar back to 2010?

Thanks guys
