I have flowmasters now, just the mufflers. They sound good, but I've been told with a X-pipe a straight though design like the Ultra-Flow works better then a baffled design like the flowmasters or the super-turbos. That and my flowmasters were not installed very well. The welding was done pretty badly.
As far as Steeda quality, everything I've got from them has been extremely high quality and they're suport is great. Its a good company.
