I have a 2010 wrx hatchback (narrowbody) which makes it hard to find exhaust systems as its a single exit. I want my car to sound nice when giving it some gas but if im on the highway or just around town nothing to abnoxious. I was thinking just a rear muffler swap to a magnaflow or flowmaster. not sure it that would make a huger difference or not.

Thanks!
