I just replaced the stock exhaust on my '88 Mustang LX 5.0L with a Bassani system: Bassani equal length shorty headers, Bassani X pipe w/ hi flow cats, Bassani catback system. It flows nice but the exhaust is louder than I wanted. My car's a convertible and it gets too loud with the top down. The drone at 2K is the worst of it. I'm thinking that a muffler change would help. I've heard that the Corsa dB series eliminates drone (resonance chambers for noise cancellation). The Corsa are a straight through pipe though. Any idea whether they would be louder or quieter overall than my Bassanis? I'd appreciate some advice. Thanks!
