Review on Flowmaster 817511 Axle Back System 409S by Leo Torres

K So if you are planning to buy this set of Flowmaster kits and you have read some of the reviews you can see that many people's reviews are getting out of control too seem to be . I call this set super perfect with perfect sound. Well I'm here to tell you that these reviews are completely correct. It's GREAT, easy to install, 30-40 minutes of basic instruments and the sound is AMAZING, yes. But then again I'm not a super engineer or someone trying to sell you these things, just a regular JOE trying to make his car sound good (06 Mustang GT) and I like the sound they make and how easy the setup is . In fact I installed them without lifting the car or uploading it, parked in the driveway and decided to give it a try, BOOM done, only 4 screws per side to remove and install these new LOVE EMs, they are worth every penny !
