Rated 5 out of 5 by from Amazing sound Car sounds like it should have from factory it's loud and aggressive. This exhaust is not for those who want a quite ride around town or freeway. The quality is amazing although I did have a few pipe ends bent but I bent them back. Best sound on the market deep notes not raspy at all

Rated 4 out of 5 by from MagnaFlow Quad I have a 2016 Mustang GT coupe, the exhaust looks and sounds great, but the Hanger hooks were off, I had a local muffler shop install the kit, they had to cut the middle hangers hooks because they just did not line up correctly. After fabricating them the mufflers started to line up correctly. MagnaFlow needs to make some adjustments.

Rated 5 out of 5 by from Sounds and looks aggressive!!! Couldn’t be anymore stoked after receiving the box of exhaust @ my door! I pulled everything out to inspect and make sure all parts were available before the installation. After installation... i conducted a fresh cold start. The sound was impeccable and exactly what I wanted! The sound Is like a deep big tube sound traveling far, has the perfect amount of rumble. When take off it rumbles enough in a discreet way, but when you get on it and shift through the gears the exhaust opens up and screams aggressively! Amazing sound !!! I would hands down recommend this catback exhaust system! Just keep in mind the rousch lower valance only works with this exhaust set up. The exhaust sits higher than stock. It would of been helpful if that was stated for this particular exhaust system. I learned the hard way of figuring it out which took me more time than expected, but made it work with the GT350 lower valance after a bit of fabrication. Installation time 1 to 3 hours depending on wrenching skills. Arrived on time delivered by UPS. The box was a little beat up and slightly opened. It could of been packaged much better than how it arrived. All parts were in the box.

Rated 5 out of 5 by from Best Quad Tip Exhaust for 2015-2017 Mustangs It's been a week since I've had this exhaust and I've already put 400 miles on it. I just have to say you can't go wrong with this Magnaflow exhaust. I loved it instantly the moment I installed it. The quad tips looks absolutely amazing, everyone needs to install quad tip exhausts on their mustangs because they deserve them. As for the sound, it is very deep just like how Bill explained in the video. I like the deep sounds more than the raspy sounds other exhausts produce like Corsa. This exhaust is very loud outside the car, you will get head turns driving with this. When I first installed the exhaust, it was slightly loud inside the car but it was not annoying because the exhaust produced a pleasant deep sound. When you are cruising, for example, 65 MPH in 6th gear, you can hear the deep sound but it is not a drone, just a deep pleasant sound and it is only a slight sound inside the car. The exhaust becomes extremely quiet when in neutral. I noticed that sound started to get lower as I drove the car more and more so you just have be patient if you really don't like that deep sound it produces. But when you rev it all the way up, it really really loud but not as overly loud as corsa which is a good thing. This is just a brief review but I will update my review after few months of driving with the Magnaflow exhaust.

Rated 4 out of 5 by from Low/deep sound I received the exhaust about about a week ago and installed it myself. The installation was fairly easy, I was able to install it in about two hours with no help. As far as the fitment goes, I had to take my car to a shop and have them put it up on the lift and do some adjusting. The left side stuck out further than the right and the right side was touching against the rear valance. Thats why I'm not giving this product a full 5 stars. As far as the sound goes it is definitely a lot quieter than I thought it would be. I would rate the loudness on the quiter side even though it had that deep tone to it. While Inside the car, the drone can get pretty loud at times especially going up hill and around 2000 to 3000 RP. If you are looking for a quieter and deeper sounding exhaust this one is the right one for you.

Rated 5 out of 5 by from Great looks and sounds fantastic! Wow! I'm very happy with this system. I've been turning off the radio just to hear it!

Rated 5 out of 5 by from Prrrrfect Easy install by anyone, sounds fantastic, quality is artwork. Much louder than stock--in a good way. Resonating drone at 2000, just have to cruise a bit faster.

Rated 4 out of 5 by from ..... I pull the trigger on this exhaust setup. Shipping was faster then expected. Quality of the catback is outstanding. Installation was a breeze. One of the inlet tubing on the muffler were slightly bent but I’m blaming that on ups. As for the exhaust itself, it’s labeled as a competition version. But after calling magnaflow directly. This catback infact uses the same exact muffler as the street series. Magnaflow claims that the sound output is in between the street and competition. So if you are expecting it to sound like the single tip competition series it does not. The sound is a nice very deep tone with a lil more raspier note passing 3k. In the cab with the windows up the sound is noticeable but not extreme. I would give this product a 5 star review if it wasn’t for the bad labeling, or lack of information on the different mufflers.

Jack, It will not work on a 18, part # 1004266 does not have the valves & will cause a check engine light since the actuators are not getting feedback.
