Flowmaster Super 40 vs. Original 40

It sounds like these Dynomax Welded muffs are louder than the Flowmaster Original 40's???? But without the resonance.

No they aren't louder. The Dynomax Welded Race Magnums have a nice deep powerful tone, very little reasonance but still bark nicely at WOT.

I also switched from Flowmaster 40's to Dynomax's very quickly as I wasn't happy with the Flowmaster sound.

With full exhaust and a lopey cam they sound like a performance car should sound. :thumbup:
