Hello, Contact Nick at Acton Custom, he installed new cobra pack mufflers in my side pipes (and several others on this site) and the pipes sound fantastic. I went with the quieter pipes so my daughter would not be afraid of the car but is sounds great. Nick is a dealer for the cobra pack mufflers and he is a great mechanic/craftsman. He is mickmate on club cobra,
