        4 Top Rated Questions

        Would these Magnaflow Axle-Backs mount to my Magnaflow Competition Series Cat-Backs?

        Is this more race car sound or muscle?

        • These would give off a more raspy race car sound rather than deep muscle.

            Well made, bolted right on, no problem. The only issue I have with this product is it's way overpriced. Otherwise I would have given it 5 stars

            traded my 2004 mach 1 for my newer 2011 gt.The Mach 1 sounded like a beast with the custom exhaust it has on it.The 2011 gt with stock mufflers was just to quiet for my liking.I ordered the Magnaflow race axle-back kit and I love it.Muscle Sound!!!!.

            Much better than I anticipated. Satisfaction level is way through the top. Slight annoying drone at 2000rpm on load but grab another gear and go. Super quiet at idle. My butt dyno says I got more HP, the weight reduction didn't hurt.

            The sound is fantastic. It definitely sounds like a v8 engine now that I put these bad boys on. There is a drone at 2000 rpm but its not that bad.

            It's the perfect tone for your mustang, it's very loud at WOT and the perfect amount at crusing speed.

            5 2011 GT - WileysDad Installation Time: Afternoon


            Had a heck of a time getting the stock exhaust to let go. After that battle the Magnaflow install took just minutes, alignment everywhere was perfect. The sound is perfect (for me), it's loud (probably too loud for some folks), it's deep, throaty and grin inducing. There is a bit of a drone around 1800-2000 RPM, which unfortunately is right at 70mph interstate cruising speed, but kick up to around 2100 and the drone goes away (officer, only 4mph over, really?) A week after the cat-backs I got the Boss 302 side exhaust installed (had a shop do that, couldn't the car high enough to get my fat butt under there). The two combined, perfect, loud, aggressive and perfect.

            Magnaflow competition axle back

            Wow!!! My 5.0 was a second look kinda car. Now its a flat out show stopper. Nothing and I mean nothing sounds as mean as this exhaust . Surprisingly quite in the cab. Everytime you rip the gas the engine screams through the exhaust. I've had at least 50 people ask me where to get this sound in a months time. Just wow! Best money ever spent. Jeff in Bakersfield

            4 2011 GT - 2008CRNA Installation Time: Shop Install

            Nice Loud Exhaust at WOT (wide open throttle)

            This was one of the first mods I put on my 2011 Mustang GT/CS (manual). I love the sound of the car when I start it and you can feel the burble when you stand behind the car. Nice loud sound when you go full wide open throttle. Deep exhaust note when idling or revving the engine. My only complaint is the drone when traveling under 60 mph. It is a loud humming sound that is really evident when in 6th gear. Otherwise it is barely noticeable when staying in 5th. I wanted the Borla Atak but when looking at pricing, it was double the cost (I bought the full competition catback exhaust). I snagged the full system on a sale and had it installed for <$900 (Borla would have been around $1800). Spent my other money on a clear bra/tint, Bama tune and Steeda CAI.

            Absolutely love it!!!

            I listened to all of the exhaust sounds mutiple times and in the end i decided to go with these. I was not disappointed. They shipped within two days which is always expected from AM's great service. I picked them up at home after school the day they came and brought them up to the shop i work at. It took me and another mechanic about ten minutes to get both of them on. I took it out on the road and heads turned and have not stopped turning since. The only thing i can say that is mildy annoying is there is drone in 4th an 5th gear at around 2000 rpms. Other than that these pipes are perfect. My dad agreed that the sound puts his Sherrod gt 500 to shame. If you're looking for great sound and the attention of everyone you drive by then these are for you

            These axles backs are very loud, but sound really good. From 1800-2100 rpm they have a alot of drone, but overall you will love these axle backs. Sounds like you got cam work done as well!!

            Very easy to install, about 30 mins. I would say if you ever will have to pass a Db test, keep your stock mufflers because these are LOUD! Great sound with very little back fire. Nothing a tune can't fix.

            Amazing Sound

            The product came very fast in the mail, only thing was my car wasn't here yet. But finally it showed up. The install was hard mainly because of the org. exhuast. Once the old exhuast was removed, installing the new exhaust was as easy as screwing down bolts. The sound is amazing, deep and very aggr. I am very happy with this choice. I would recommend this exhaust to any and all who have an 11 mustang.

            These look and sound awesome! Some bolts for the stock mufflers were difficult to get to. However, with some patience they finally came out. If you want a mustang that sounds like a racecar, than these pipes are for you!!
