I would like to know what is the best buy for an S-code fastback . I want to know where to buy the complete set up. Since in P.R we do not have Judged shows I would like to get the more original looking system with the correct exhaust tips but WITHOUT the transverse muffler that I have read is not the best way to get the most out of the system.Where did you buy yours and which muffler do you use with the system. I believe that the diameter is 2'. All opinions and suggestions are welcome.
