I put a set of BBK shorty headers and a BBK off-road H-pipe on my '88 5.0 LX, which already had a set of Magnaflow mufflers installed. I expected the car to be a bit louder...but it's LOUD now...which is fine at times, but this is a daily driver that I spend an hour in driving back and forth to work and I suspect I might get tired of the drone eventually. Any ideas of how I can tone it down a little without restricting flow? Any muffler options that are known for being a bit quieter than the Flowmasters?
