What I don't want is the ol popping Smitty's sound when you let off the gas. Hooking up to dual glass paks might have that effect.
I contacted FlowMaster to dial in a 'sound'. They are the ones that suggested the Delta Series Muffler. And here's the real question...is Patrick's really a two in/two out? Or does it just 'mix' the dual in and provide the appearance of a dual out?
In other words; no net gain.
