I know a number of folks who bought the FlowMaster system weren't pleased with the drone at highway speed, nor the fit of the system.
I just installed the Corsa catback system on my SRT8 yesterday. Yup, it's quiet when you want it quiet, and obnoxious when you mash the throttle down. The fit was excellent and only took minor fussing with to get the tips to line up correctly. The sound is excellent too.
Granted, the Corsa system is pricey, but if you shop around for the best deal (and look for "online discount codes"), bargains can be found.
My Corsa cat-back system cost me $1,169.10, including S&H. I thought that was a very good deal.
