Question:
How to quiet a new dual exhaust sys.that has a heavy droning noise inside the car?

Expert Reply:
Loud exhaust noise on the inside, with a deep drone, sounds like it could be a system with glass packs or another modified exhaust system that has a straight through type of muffler. If you switch the straight through mufflers with chambered mufflers it will take care of that issue.
You will also want to check to see if there is a leak in the system somewhere, possibly ahead of the muffler and behind the headers. That happened to me once and it was horribly loud. A muffler shop should be able to help you out with new mufflers and determining if there is some other issue.
The products we carry are not going to help quiet loud exhaust but chambered exhaust components would.
