DaleMX Posted September 25, 2005 Share Posted September 25, 2005 I bought these to quiet down the LS1 a bit. These are Magnaflow 2 1/2" pipe size X 4" case X 28" total length (22" muffler zone). Gonna install them tomorrow. Just using the voice test they really muff me out good. The dog's would not come when called through them, so they must work. http://www.circuitflex.com/Magnaflow1.jpg http://www.circuitflex.com/Magnaflow2.jpg Quote Link to comment Share on other sites More sharing options...
DaleMX Posted September 26, 2005 Author Share Posted September 26, 2005 They really quite it down above 2000 rpm, but the exhaust still exits in front of the differential with a couple of turn downs so the drone is still there. Sounds mean as all getout. Next step is a 2 X 2 1/2" to 3" Y then out the back. Quote Link to comment Share on other sites More sharing options...
