I will appreciate the comments of anyone who has experience with Fabspeed exhaust. This is for a 2001 986 S. I am looking for a bit more sound and was thinking about installing the secondary Cat bypass pipes with stock muffler. Alternatively, I may install the secondary Cat bypass pipes with Fabspeed muffler. I know it is all subjective, but I don't want "obnoxious" noise, just more sound than stock.
