ok here is what i have got i have a 1987 RX7 N/A 6 port and i am building my exhaust for it ( i am starting with a cat back for now runing a single pipe out driver side with just a resonator and a muffler) but i can not make up my mind on which muffler to use i have heard about RB and Bonez and CORKSport but wanted to know about any other possible options i have been looking at borla and magnaflow for their nice low tone now i know that their is no point in makeing a rotary quiet but i just don't want to have afart can on the back of my car.

thanks for the help
