Help! Does a silencer hinder performace
 

The hi-flo cat you guys see in my sig is really a gutted cat or basically a midpipe - got shafted off partstrader. Anyway Dave at KDR said that a silencer "won't" hinder performance. I've heard some different stories - I'd like to hear from people that actually have silencers and use them. Can a silencer really quiet down a dp, mp, N1 single with non-sequential set-up???

of course it will hinder performance. Though it mostly depends on the design of the silencer and muffler. On an N1, I don't think I've heard many stories of power robbing silencers..But you don't really need performance when you go to the grocery store, either, do you? :)

Of course it robs power. Anyone who says diffrently is a moron. Both HKS and XS Engineering have seen anywhere from 15-20 rwhp loss with a silencer in.

Also with the silencer some people cannot reach full boost or run rich.

My car was tuned for performance w/o the silencer. When i run the silencer in my car runs rich as hell sincethe boost curve gets all thrown off.

My Apex GT with the silencer installed dropped the boost 1-1.5 lbs during 3rd gear runs. TOTALLY hinders mi amigo
