1979 Malibu 3" x pipe no mufflers
Mild 350 Comp XE274 flowtech 1 5/8 long tubes with universal flowtech 3" X pipe no mufflers with side dumps
2014 Silverado muffler delete
5.3L engine. Just had the shop remove the muffler and install a piece of straight pipe. Cheap option. Doesn't have a drone inside cab and can barely here it when cruising but sounds great wide open.
