I also contacted RedLine/DTS/ActiveAutowerke and no go on the mod. Seeing no one in SFL apparently knows of the mod or has to balls to attempt it I dropped the exhaust on the car this weekend and went ham on it with an angle grinder using all the DIY videos i could find as reference.
My oem mod should be back from the welder this week and I'll have it back in the car this weekend. ill be posting pics and have no problem meeting up at one of the local meets for anyone interested in a test drive/listen
