I have LT pacesetters, ceramic coated, and i decieded to go with a true dual set up that involves, a dr.gas x pipe, and 2 sweet thunder chambered mufflers. i was thinking of going with 2 18 inch stainless steel mufflers where the factory muffler rests, however I saw a pic on their website of a member on here that has four total on his car, two near the tail pipes, then two, under the car, (true dual exhaust as well) would just 2 mufflers be too extreme cuz thats what i want or what would the pro's and con's be of having 4? here is the link:
