Review on Flowmaster 817511 Axle Back System 409S by Chris Dildine

After about 2 weeks trying to figure out whether I should stick with what I know for sure or try something new, I stood in my heart and chose her. I can't be happier I guess. This is my second Mustang and this is my first upgrade to it. and man man man what can I say he's alive! The sound is downright aggressive when accelerating and idling. People definitely notice the difference. Now my 2006 Mustang GT sounds like the pony they were supposed to be releasing. I am happy about this purchase. My roommate and I installed it in just an hour and a half, but mostly because we talked a lot and it didn't work. Easy installation. Go Flowmaster, you've done it again. And if you're wondering if you should buy this, then yes, you should.
