Does anyone know of a good custom performance shop/garage that specializes in SRT's in the Detroit Metro Area?? I've had my Jeep for 10 months now and I all have done to it is the CAI, Cat back, jet stage 2 module and SR7 plus ZR3 shifter. Looking to add ported/polished heads and long tube headers, but don't want to order from someplace across the country. Any 313, 248, 734 or 586 SRT8 owners here wanna give me a suggestion?? Thanks!
