        Does this muffler really increase hp.

        • There are dyno proven gains in conjunction with this exhaust. This and all MBRP systems will undergo Dynomometer testing, as well as hundreds of miles on road and track as well as other refinements to get the maximum performance.

        Do you have to buy 2 because it says each?

        • Purchase of this will include the entire axle-back exhaust system and the hardware needed for installation.

        With Muffler Delete does my 18 need a tune? I also plan on x Pipe with both installed is tune required?

        • Neither an axle back exhaust or mid-pipe upgrade will require an updated tune. Any upgrade to the catalytic converters and forward will require a tune update for the vehicle to operate properly.

        Would you recommend the MBRP or the Roush axle back? Personally from videos they sound really close. But there's also a $250 difference as well and I am just not seeing the extra money worth.

        Will these fit a 2019 mustang gt with active exhaust?

        • No this would not fit your Mustang with an active exhaust system

        Why does the sound rates lower than Roush exhaust when this is actually a muffler delete? Also, wouldnt make the same soumd if you just delete your pipe and weld tips? 1 answer
        Would they fit a gt350 rear valance ? 1 answer
        It says this reduces weight over OEM mufflers but nowhere online, either here or on MBRP's site can I find exactly how much weight savings that is. Please don't answer me with a guesstamate either, I wanna know exactly how much weight you drop off a '18 GT by doing this upgrade. Thanks! 1 answer
        It says "each" so would I have to order 2, one for each side of exhaust pipe? 1 answer

            Had this exhaust system installed on my 2018 Mustang 5.0. It now sounds like a Mustang should, heavy growl. Love it

            Great buy

            I love the sound of my Mustang now it sounds like a real muscle car should. The only change I made to my exhaust was the axle back. Very little drone while cruising but has that extra umph when you give her the gas. Could not be happier with this purchase.

            Great Quality Exhaust

            If you are looking for a axle-back, this should be on the top of your list. The stainless steel quality is amazing for the price and the exhaust tips stand out. I currently have this system with the stock resonator, and it is loud, for 2 days my ears hurt a bit and the drone was kinda bad but I got use to it quickly. The car pops occasionally when revving it high and it sounds raspy. I plan on pairing this with an H-pipe to eliminate the raspy noise from this muffler delete axle-back from MBRP.

            MBRP Axel-Back

            Great product, a little wobbly after the install so you might want to put a small tack weld on it.

            Loud

            This was a great purchase, if you want loud I recommend on doing the X-Pipe resonator delete with these axle backs. Sounds amazing. When you take it at like 1500 rpm its quite and relaxing for those long drives.

            MBRP for the Win!

            I can't lie, MBRP was my second choice for the Axel-Back exhaust because I had Flowmaster on my 91' Mustang years ago and loved the sound and just wanted to continue with the sound that Flowmaster gives you. I watched a bunch of videos on YouTube and ended up liking the way MBRP sounded and then I saw the price and I was sold and so glad that I chose MBRP because my Mustang sounds like a beast now!

            Good stuff

            Sounds great . Opens up the engine a little more than stock with some burbles as it breaks in more and more. Definitely need an x or h pipe with this set up to really add that raw 5.0 tone to it . Great exhaust system tho . Would definitely recommend especially if ur low on money

            What It Should Have Sounded Like Stock!

            On my old 2010 GT I had Flowmaster Outlaws and an Off Road X-Pipe so my 2019 aeemed way to quite stock. I did enjoy actually being able to have conversations in the car, but I needed it to sound louder meaner. These do that perfectly. It sounds so much better and louder without going over the top. I can still have conversations in the car (surprisingly no drone here) and be able to unleash a symphony of violence with just a little acceleration. I'm thrilled with the sound foe such a great price and it arrived a day early!

            Very balanced sound.

            Very easy install. The tone is very deep and really has that muscle car growl when pulling out. The system is quite loud with the windows down at WOT. Cold start ups can be loud, especially in a garage. The system pops beautifully when downshifting as well. Overall would highly recommend.

            Just what I was looking for

            Overall I am very pleased with this purchase. Essentially this system is a muffler delete however the overall presentation is worth the buy. The tips looks great everything is uniform. Now the sound is exactly everything I wanted. Cold starts are a tad loud but doesn't last long. Under acceleration it sounds great. Deep V8 sound and rumble you can't beat it.....

            I paired the axle back with the heart throb x pipe on my 2018 mustang gt and it makes the car come alive. Very aggressive and loud as well but has a deep tone and not raspy at all. Fully satisfied with the purchase and now the exhaust note matches the look of the car!

            Amazing axel back exhaust for the price.

            The mbrp exhaust made my GT sound amazing. It has a nice roar to it but at the same time it's not obnoxiously loud. It also makes the stang look way better with those 4 inch polished tips. I definitely recommend this exhaust.
