        Sounds like a V8

        This axle back is awesome. It makes my engine sound like a v8, it's really deep and its loud but not too loud. No popping noise, the smallest amount of drone but its not even annoying to the ear it's like a hum and it just makes it better. Installation was super easy, took me about 2 hours. Best exhaust sound for a v6. This is for those looking for the deepest sound for their v6 with no rasp, drone or popping

        SLP Power-Flo Exhaust

        I have a 2011 V6 Mustang and I wanted a loud, deep exhaust note. I heard other brands on youtube, such as Magnaflows, FlowMasters, Rousch, Ford Racing and SLP. I really loved the way the SLP's sounded. It's very lightweight, compared to the stock mufflers. Do your research before installation if you're going to do it yourself. Basic hand tools and jack stands are needed. The difficult part of the installation is removing the stock mufflers. Within the first week, you'll be heard from a block away. It'll feel like you're in a Shelby. The cabin sounds very loud with a deep rumble, so this will be your music. Over time, the tone will be a little more subdued but still noticeable when you're on the gas pedal. For a V6, this is the best exhaust you can get. I highly recommend this.

        Nice exhaust !!!

        Well after reviewing several different exhausts it seemed to me that the slp powerflo exhaust was underestimated little do people know this exhaust in my mind is THE best especially bang for your buck. Drone? Virtually none.. I highly recommend this product for anyone looking for aftermarket exhaust on your stang! It sure does turn heads and makes your stang roar!

        SLP Axle Back Exaust Outcome

        Overall a very nicely built set of mufflers and beautifully finished tips.,Very high quality.Put them on with my brother in the garage with a jack and stands,ratchet,couple of sockets and a sawsall.took about 2 hours total.The hardest part was getting the old stock mufflers off,which by the way are very heavy,unlike the new SLP's.You have to spend a little time making adjustments but overall very nice fit.The new SLP's are a lot louder and the more you push the throttle the better they sound.At cruising speeds there is a loud drone but i am happy overall.
