I figured I would start a new thread about this vice high jacking someone else thread. After going to 4 different Muffler dealers in my area (upper PA area), I found either they have no idea how to install one, think I am dumb and tell me it can't be done. Even had one tell me it would mess up my computer and i would have to get the car reprogrammed for the dual exhaust. Only one offered to do it but with putting a dual in/out muffler because they say two muffler would not fit. a bit cheaper ($400) but I don't think it will sound the same as a true dual exhaust. first question..Could I buy the magnaflow, corsa, etc and just do it myself? should I try to get an R/T system off someone? would a one muffler system sound the same? probably won't happen till after Christmas but i wanted to start looking now. Thanks for any input a head of time.
