        Does these mufflers have a loud interior drone?

        • The NXT Axle-Back Exhaust produces a minor level of drone but nothing that would generally prevent from purchasing. Feel free to refer to our review video of this exhaust to get an idea of the exhaust sound.

            Very good

            4th set of mufflers on my 08 GT. These are by far the best. Installation was a bit fussy but they sound great with off-road H pipe.

            Drones at 2k

            Has a fairly annoying interior drone at 1800-2k rpm but I expected that from the reviews, cold starts a bit louder than I wanted though. Overall they look good and sound good for the price and install was easy. (Expect to bend the rear hangers in a bit as they both were to far out but it wasn't a big deal)

            these mufflers sound awsome. nice n quiet when cruising, but really come to life at WOT. Install was pretty easy, about 30 min. in tha dirt. Thanks AM.

            Growl

            At first I wasn’t really sure I liked the exhaust. Had them for a week and I couldn’t be happier, old school come get ya some growl,a little noisy on a cold start. I don’t get a drone noise at least yet I haven’t. Get on it a little bit it’s a real head turner. Definitely worth the money and didn’t have to spend a bunch of Ben Franklin’s.

            Nxt axle back exhaust

            Looks and sounds great. Some minor adjustments to make it fit right. Drone around 2K RPM that will take some getting used to. For the $$ I would do it again.

            Awesome Sound

            I really like the sound of these pipes.the chrome tips are easy to clean and high quality material. The only downfall is they have a bit of a drone noise inside the car at certain low rpm. Still I highly recommend this product.

            Awesome for the Money

            Install was fair, first side was a little more difficult than the second. Total process took less than 2 hours and that includes lifting the car. Removal of the hangers is the way to go, especially when putting the new exhaust back up. Fit was a little off, had to bend mounting points a little closer together. Sound is deep and aggressive; above 60mph there is some drone. Overall, looks great, weighs almost 6lbs lighter than stock exhaust. Definitely recommend. Could be the best bang for your buck in axle back exhausts.

            Get what you pay for

            I want to preface this by saying that I hadn't had the time to do a burn in yet so these are my initial expressions. Sound - good at higher RPMs but a bit too quiet at lower RPMs, however this being only an axle back can't expect it to work miracles with a stock exhaust system up front. Fitment - the front hanger prongs are too wide apart, and require bending into place, tip: if you have ratchet straps you can use them to bend in place pretty easily Drone - yes there is drone, it's really bad at around 2k with partial throttle acceleration. Hoping it will decrease with burn in. Just cruising it's about as quiet as stock maybe a tad bit louder. Installation - aside from fitment issues installation is very easy, hardest part is getting the stock exhaust out. Easiest way to do it is unbolt the front hangers completely, which requires a somewhat angled wrench to get at the bolt directly above the muffler. Then on the driver side there are two bolts on the left hand side. Passenger side has only one bolt on the side both relatively easy to get to. As others have said reuse factory clamps the ones in the kit are not very good. The whole ordeal took me roughly 4 hours including figuring out the extra hanger bolts and a quick trip to autozone for an angled wrench.

            Exhausted

            Great Axle-Back system, not too loud, but loud enough to know that you have something in the rear. Very easy to install and quality of the mufflers is excellent, and of course delivery was right on time.... you cant beat the price for a nice sounding system

            Nxt Step exhaust

            The Nxt Step exhaust is what I was looking for. A bit louder than the stock mufflers, but not so loud you have to yell to talk to others in the car. Has a more aggressive tone at idle, more noticeable under power, ounce you hit cruising speed the tone is great. Fit and finish were great. The exhaust tips sit the same in the rear valance. No making anything fit. I have seen reviews about the clamps that come with this exhaust. I cannot comment, I did not receive any clamps, so I did reuse the factory ones. I am happy with the results, would recommend, and would buy again. THANKS!!!

            Good purchase

            Great quality. Perfect fitment. Great sound. Little bit of drone at 2k rpm. Installed these on my 13 GT with Kook L/T headers, High flow cats with an X pipe and resonator deletes.

            It's pretty freaking loud

            It's a good loud, very vintage muscle sounding and extremely deep exhaust noise that leads to a loud and beautiful up close noise but deep enough to where the sound dissipates in the air better than a raspy treble setup... cops are less likely to hear you ripping down a street or freeway with these but you can definitely be heard when you need to

            Installation was just over 1 hour in the garage. Used the factory clamps. Very impressive throaty sound at a idle. Really sounds great when you get on the throttle. Would highly recommend these pipes if your looking for that old muscle car sound. Makes the neighbors take a second look when you drive down the street.

            Sounds ok

            Super easy install. Its sounds like the price. It was on the cheaper side of the axle back. It def sound good but doesnt have that throaty crackle i was looking for. Also 2k rpm droans pretty loud.
