Like the previous posters have said it is very easy to replace the muffler with the Mufflex system because its bolt-in.
With buying the mufflex system vs full magnaflow system would you be able to tell any difference do you guys think? I thought i heard the exhaust is full SS.
I will be getting headers and a Magnaflow Y pipe. Just is it worth the extra money for full catback system.
