WS, as far as I've gathered, is a pretty nice quality system. The sound should be pretty subdued... quiet for normal driving, deep at WOT, but not rattley or buzzy. Thats probably what I'm getting in a month or two to replace my dryer-ducting muffler :exnbp: My only concern is the big tip. I'll prolly hack off the tip and have the shop weld on a 2.5" slant cut SS pipe.
In terms of power... Its probably better than dryer ducting...
