    SGF11R is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Nice system for the money This system replaced a flowmaster crossflow setup on a lowered 1976 Firebird. The pypes system fits much better than the flowmaster, and the mufflers still have good ground clearance. Plan on welding or using band clamps though. Every joint leaks with the supplied clamps. This is personal preference, but I wish I went with the violator mufflers. The race flow are just too quiet, and not deep enough for me. They almost sound like the flowmaster they replaced. Not a plus in my book.
