I don't know much about Flowmaster, but I seem to recall having read, on more than a single occasion, about GTO owners using 40-series mufflers on their rides. Subsequently, this leads me to believe that this muffler is available for our application.

i dont know about that, if you look on flowmasters website they dont even have a kit for the GTO still. i just heard people grabbing the 40 series as it recommends it as a universal muffler, they also mainly use them on the 60s muscle cars. honestly i wouldn't go with them cause of their lack of commtiment of making a system for the GTO.

thanks guys. i'll have to think it over. have a great holiday

Just an opinion here...but you will not find a muffler that sounds better than a 40 series Flowmaster. Period.
