Hans, regarding the inlet sound supression. The Car Chemistry discs and the Vortex cone are more effective just after the primaries and before the muffler. From the CC specs: " The further back the insert is installed, the less effective they are at reducing sound " " The insets work off of the strength of the exhaust pulse as well as the heat of the exhaust " " A rich fuel mix will create a much louder exhaust note "
There are also two models of the CC discs, one having additional sound control.
They also make a series of their discs, 7 in total, which will fit inside an exhaust pipe, i.e. make your own muffler, referred to as " Side Pipe Inserts ", 3", 3 1/2 " and 4". However, the length is 33".There is a " Side Pipe Silencer Kit " which has 4 discs. Intended to replace the existing turn down on the side pipe as a bolt on rather than welding. From the picture, does not have a support bracket.
