        Better Muffler for the Money

        I had previously purchased the Pypes muffler and disappointment wasn't long in waiting. The muffler started rattling within months. The Magnaflow installed better, hung right the first time and the sound doesn't resonate inside the vehicle. It cost more, but the quality is worth the cost. Better to spend more now than eat the cost of a Pypes muffler like I had to.

        Dont Buy

        Don't buy this product it is very quite. I called customer service and they told me once I installed it on my vehicle and turned the vehicle on that I could not exchange or return the product. Also that this is one of the quietest muffler they have.

        Axle Back

        Love the sound and the ease of installation but I’m very unhappy with two issues. #1 is that the tailpipe end fit right up into my plastic bumper and was nice and snug. The problem is that it melted my bumper at the curved out area. Not happy!!! Then an issue I haven’t resolved yet is the constant banging going over bumps. The factory muffler had three mounts where this one only has two. There is no hanger mount in front of this muffler so I’m going to have to cut the welded mount off the old muffler and get it attached to the new muffler to stop the constant banging going over uneven road. The nice sound is not worth the $350 and melted bumper!!!!

        Great Product and sounds great

        I ordered this about 3 1/2 weeks ago and it was on back order. I though to myself that I would just change my order but then I though.... If they are out of stock on it, it must be pretty good. Well I was Right and it was worth the wait. From the time I got the car up on the ramps in the garage Found my 13 mm and 15 mm sockets and wrenches, a grand total of 25 minutes to get the old stock (COPD) muffler out and hang a big shiny chrome muffler in its place. After I got this on, the wife and I took off down the interstate at 800 mph and we could talk just as normal as before. If you Stand on the loud petal, it will let you know what you just put on the back end of your Mustang. Well worth the wait and sounds Great.

        5 2007 V6 - Jim3npt Installation Time: Afternoon

        REALLY great sound for a V6 Mustang!

        Perfect fit and easy to install. It took about 2 hours for me to install it, but I was just enjoying myself and taking it easy on a lazy Saturday afternoon. The chrome tip centered up perfectly in the bumper cut-out without any need for extra adjustment. The sound is fantastic, and not too loud for our convertible, even on a long trip. My wife even loves the way it sounds. The smooth, deep tone really comes alive under heavy acceleration and when you get the revs up over 3000, the sound is SWEET! But it is only slightly louder than stock at cruising speeds, which is really nice if you want to have a conversation or listen to some tunes while you're driving. Someone told me it would sound like an Infinity G-35, and that's EXACTLY what it sounds like. If you want a really loud, obnoxious muffler, this is not the one to choose. But if you want one that gives your Mustang a really healthy, strong, classy tone without the nasty flutter, raspiness, popping or hollow ringing drone of certain other systems, that turns heads but doesn't annoy anyone, this is a GREAT choice.

        The Difference is Amazing.

        From the minute I hit place order to the day I crawled under the car and bolted this up I was anxious to hear what my baby would sound like with this new muffler on there. Once I started it up I had a big smile on my face. Outside the car it sounds even better, especially when driving. It isn't to loud on the highway, up in fifth gear, but drop down a gear and it sounds awesome. I believe this is defiantly worth the money if your looking for something to make your V6 sound great. And American Muscle was right on point with delivery and instructions.

        Good stuff

        Out of the box, quality you can see. Difference over stock at idle is barely noticeable , but has a nice throaty tone when you jump on the fun pedal. No drone at 2000 rpm, no ricey sound, and the fat tip fills the bumper cutout nicely. May still look into duals in the future but for now quite satisfied and do recommend.

        Magnaflow Muffler for V6

        This. Muffler. Sounds. AWESOME! Taking off the OEM was a bit of a chore, required some serious muscle, but, man, was it worth it!

      is this the loudest you have for the V-6 mustang If not which one would it be because I'm having a hard time deciding but I know I'm going for loid

      • The Borla axle-back would more than likely be the loudest option.

      Comparison to Flowmaster What do you get out of this vs. the axleback Flowmaster you have on your website (sound/performance wise)?

      • 1. A way better construction and life of exhaust. 2. Better Sound and High Flow Through. 3. Easy Maintenance and Care. Have had these on a 2001 V6 , 2006 V6 and 2010 V6. very satisfied with them vs Flowmaster which i had on a 1966 V6 and switched for sound and performance.
