Here is a good example:
My wife hated smell from my full Dinan setup. So I sold it and bought Akra slipon.
She was ok since it had no smell. Then I wasn't happy about power so I got an Evo mid pipe without telling my wife (since she ain't gonna say "go buy it honey, I love to see your M3 pulling harder").
I had it on my ride for about 3 months but she never noticed I changed mid pipe!
Smell wasn't bad at all in normal driving. But when I'm alone and driving really hard, I can barely smell from HFC.
Go for it. You're not gonna regret and you're not gonna get annoyed by smell either.
