Nice system
Perfect fit, just had to cut the x-tube as described! And I cut away 3 bolted headers flange and the front pipe fit without cutting it! Bought the street and strip system, perfect and good sound during normal driving! The downside is the clamps, bought other clamps around the entire tube instead of not clamping the tubes, facilitates future disassembly!
great buy
this is the second set I've bougth and installed. They both fit good with little tweeking. I use the race pro mufflers because I heard that they were actually quieter.
