Corvette Central is pleased to introduce our exclusive correct sounding dual outlet mufflers for the 1984-1990 Corvette. These are manufactured and welded in USA by Corvette Central (cases are manufactured in Canada).
On the original 1984-1990 dual-outlet muffler, the inner outlet tube is for appearance only, and is blocked off. With our design, the outer outlet tube is open, but the inner outlet tube is connected to a small diameter resonance tube. This design provides the correct sound and quietness of the original design without the annoying low-RPM drone.
Unfortunately we don’t. Here is a link to what we have to offer for 1991. https://https://www.corvettecentral.com/search?CurrentSearchCategoryId=&q=muffler&Years=1991
Do you carry no drone mufflers for 1991 and what’s the difference from all the rest of the c4’s
Thanks Ron
