For the past 5 years I have fitted Flowmaster mufflers to my '68 Camaro with LS1 engine. It's got a pretty decent camera, headlines, and setup. I like the sound of the Flowmaster mufflers but they are too loud. Sounds fantastic. Still has a strong sound at idle and sounds amazing at full throttle. Excellent muscle car tone. The noise level in the cabin is excellent, much better (lower) than before the trip.
