I drive a 1992 Buick LeSabre Limited 3.8L, I dont care if it adds power to the car or not, I want something like a part that goes on the exhaust to make it sound like a pack of rockwhilers are in it, I tried flowmasters but flowmasters dont make one that will go on, I need to know what my options to achieve this effect are I know there must be some part I can buy to do this.
