All the exhausts I like have 3" piping. At the same time, I'd like to keep my car somewhat quiet. I don't like silencers, plus most look more restrictive than a stock exhaust, while I still want my exhaust to 'perform' decently at all times. I know the HKS Silent Hi-Power has a 2.5" section before the muffler which is what quiets it down, so I thought using a 2.5" gasket between the sections of a two-piece 3" catback might produce similar results.

Ah, bummer. Thank you for the info though.
