Impressed with the workmanship; mandrel bent nice welds etc, not with the innards. They only lasted about 2.5 months on my Firebird before one started rattling like hell.

Don't bother.

Solo HFCs are direct fit cats with much better flow. See the attached pictures. Had mine on since April 2010 with no problems.
