silverss05 Posted October 8, 2008 Report Posted October 8, 2008 Is anyone here running two Magnaflow 4x9 owal mufflers? I am wondering about the sound levels and also performance. I am looking to replace my two flowmaster 40's. Sometimes the flows sound like a choking dog or something in the lower RPMs. Just looking for some help as to what to switch to. I am also going to be adding some Bassani mid headers later on down the road. Quote
