Review & Installation Video

Review & Install Video

The Heartthrob four-inch aluminized cat-back is available for any 3.5L EcoBoost owner, who's looking to get the most budget-friendly cat-back on the market with a single side-exit design, coming in right around the $400 mark. Now, for everything you see here, this is all just barebones material, so it's for the guys out there who are not concerned about appearance, just concerned about the sound. This one will arguably produce the best sound for the 3.5L EcoBoost F-150, which we all know is saying a lot, because the EcoBoost produced a pretty much less than favorable noise. Now, with that said, the install is going to be very, very simple, so expect a one out of three wrenches on our difficulty meter. The first thing I want to touch on here is going to be the exhaust sound, which honestly does not disappoint. Now, obviously, it's not the most attractive system in the world, all natural materials, no real exhaust tip. But as Justin would say, this is a "don't judge a book by its cover"-type of exhaust, because arguably it produces one of the best sounds for your 3.5L EcoBoost. Now, we know from the factory, they produce pretty much a less than favorable sound. Now, in this case, in my personal opinion, you're getting a very unique sound that kind of beefs up that 3.5L motor and gives it an aggressive note. This, however, I will say, once you get on the street will start to give up a slight growl. But once you hit the highway, or even at idle, dead quiet. I'll be giving it a very, very generous three out of five on our loudness meter. Now, to reiterate, this is in no way, shape, or form, meant to be any kind of styling part with the single side-exit design. It's manufactured right here in the U.S. out of a four-inch aluminized steel tubing from top to bottom. Obviously, it's a massive bullet-style muffler. This aluminized steel that we here isn't the highest-quality materials. Honestly, it's more of an entry-level product meant to keep the pricing down. But it does come with unrestricted mandrel bends for a more free-flowing design. This is definitely not the best choice for the guys out there in any wintery weather areas, seeing a lot of salt on the roads, as it might shorten its lifetime.But as I mentioned, that is simply just to keep the price down, making this one the most budget-friendly option on the market. Now, with that said, this does come with the four-inch diameter tubing, which the turbos do love. So it does produce a very, very nice sound from the turbos, of course. But on top of that, it also deletes the factory resonator. So keep all that in mind when you're shopping around. Speaking of that price tag, everything you see on the table here from the Heartthrob option is going to come in right around the $400 mark. Nothing flashy done to this option, barebones materials, no polished finishes, no powder-coatings. So if that is what you're gearing towards and you'd like a more attractive tip coming out the side exit, there are tons of different options out there, including the MBRP, which is probably your best bet as far as budgets are concerned. Shifting gears over to the install portion of the video, as I mentioned in the very beginning, this one is going to be pretty simple, straightforward, one out of three wrenches on our difficulty meter. However, I will say there's one added extra step that you might have to tackle. What I mean by "might" is, you can see here with our extension pipe, depending on your cab size and your bed length combination, you might have to make a single slice to this [peer] extension pipe. You'll measure twice, cut once, and you'll be done with that, and you can move on to the bolt-on install portion here. Which by the way, just a simple ratchet and socket set will do the trick. All the clamps and flanges are included in the kit. A very simple swap here, aside from the cut you'll be making there. Overall, you should be able to tackle this one in one, two hours, tops, at the absolute maximum. So when it comes down to it, getting to the nitty-gritty stuff, you'll have to unbolt your factory cat-back, obviously, starting from the tip, moving your way back to the mid-pipe, and just toss all that stuff aside. It's really just a matter of unclamping everything and pulling them out of their hangers, and then removing it from the mid-pipe flange. Once that's taken care of, just work your way backwards after you make the cut to the extension pipe, if you need to do so. Once that's taken care of, you can start by putting up this front extension pipe, going up to the mid-pipe, attaching the flange, which is already on the tubing, to the one already on your mid-pipe. From there, work your way back to the muffler, and then of course there is no tailpipe tip. So just it kind of ends with the end of the piping. With that said, an hour or two at the absolute maximum, one out of three wrenches on our difficulty meter. That pretty much does it for me. If you're the owner of an '11 to '14 3.5L EcoBoost F-150, check out the Heartthrob four-inch aluminized cat-back exhaust system, available right here at

Great Sound, Ample Power. Roaring with a deep, predatory, highly-aggressive exhaust note when you’re starting your F-150 or accelerating, the Heartthrob 4" Aluminized Cat-Back Single Side Exit Exhaust subsides to a near-stock sound level when you’re cruising at a constant speed. Regardless of whether it’s bellowing its defiance or running deceptively quiet, the Heartthrob Cat-Back delivers plenty of augmented power. By letting exhaust streak out through 4" tubing, past open mandrel bends and a free-flowing welded muffler that deletes the factory resonator, the Heartthrob generates up to +45 horsepower and +58 ft/lbs of torque by clearing the engine of stifling backpressure. This Cat-Back system is 49-state legal and improves your F-150’s throttle response and shifting smoothness, along with its fuel mileage – by as much as 2 miles per gallon.

Straight Forward, Tough Design. Built with a no-frills, no-nonsense spirit in the United States, the Heartthrob 4" Cat-Back Exhaust features 4” aluminized steel tubing throughout, keeping costs down while providing anti-rust and anti-corrosion properties. The muffler is also aluminized steel and features a free-flow design to match the unrestricted mandrel bends of the piping. The exhaust tip exits in the standard location behind the rear passenger-side tire.

Simple Installation. The Heartthrob Cat-Back Exhaust System can be installed completely with hand tools, needing no welding, or drilling. The factory mounting points are used, while a full set of hardware and clamps is included with each exhaust system. Depending on your cab and bed size, some cutting to the tubing may be required.

Application. The Heartthrob 4" Aluminized Cat-Back Single Side Exit Exhaust is made to all cab and bed sizes available for the 2011-2014 3.5L EcoBoost F-150s.

      Is there anyway you can purchase the muffler separate?

      • Unfortunately the muffler is not currently offered separately.

      Will I lose some of the low-end I've heard that you can

      • This Heartthrob 4 in. Cat-Back Exhaust System should not cause a decrease in low-end power. With the larger diameter piping it will decrease back pressure significantly. If your in an area where you are susceptible to low power, such as in a high altitude area, a tune would certainly help with this exhaust.

      Will tuning be needed or required by changing the stock exhaust to the 4" heartthrob on 3.5 eco boost 2013 f-150

      • With this Heartthrob exhaust, tuning is not required for proper function. The vehicles computer is capable of compensating for the added airflow and exhaust.

          Heartthrob 4 in exhaust

          This kit fit perfectly and sounds great. I paired this exhaust with an Airaid cold air intake and a BBK 73mm throttle body. The 3 upgrades together are awesome.

          Awesome system!

          It took longer to remove the old exhaust than to install the new exhaust. Pay attention to the well written instructions. Awesome sound, great look. I was a little bummed that the exhaust system didn't come with stickers though.

          Works as described

          I am pleased with the sound. Can tell a difference in throttle response. A Lot more air movement to allow the turbos to do what they are intended for. Truck does not sound like a sewing machine anymore. Followed instructions, but still needed a little adjustment. My advice is to dry fit before cutting and take measurements. Had to remove one of my hangers on frame because they were too close together to allow the muffler to fit correctly. Very happy. Would recommend to others.

          Do not buy.

          All I can hear in the cab is drone. I can't say its a bad set up, its just makes the worst drone sound at anytime you are gaining speed. Idle and cruise aren't so bad, But if you are traveling 70mph and trying to have a conversation, the drone is going to be mildly in the middle of it. I have extreme buyers remorse. At this point I am looking for someone with a new truck to trade my exhaust system for their stock system. (willing to give this thing away just to get a stock system) Lots of noise, no power gain. Like I said, there is nothing to fault HeartThrob about, its just a drone'y beast in my experience. Makes the engine sound like its working really hard during normal acceleration. I can kinda hear the turbo's a bit more, but the drone drowns out much else. I can't say I noticed any type of performance gain. Put your money toward an intake or programmer instead, that's where I noticed the biggest gains in my experience.

          Not Very Loud, Difficult Installation

          I have a full size F150 with an extended cab and I still needed to cut about 6" off to make it fit. The instructions were terrible. They were only small black and white photos with no step-by-step instructions. Basically you get parts and bad pictures with no install help. It took hours to install. The noise is very subtle from stock. Not much of a change. I would not recommend this one for the difficultly level and little change in sound.

          Heartthrob exhaust

          I am happy with this product, although one of the hanger brackets was incorrect for the last one and I had to go to a muffler shop to purchase a clamp that is why am only giving it four out of five stars .

          Heartthrob exhaust 4 "

          The installation for this exhaust took only 1 hour. By applying the 4-inch heartthrob exhaust has really woken the true power of the turbos along with airaid filter and programer. The parts fit very good and tight no exhaust leaks at all once installation was complete.

          2013 FX4 Ecoboost

          Let me start out by saying that this is a V6 truck it will never have the deep rumble of a V8 big block. However, I think that heartthrob has done an excellent job in providing a quality product at an affordable price point. the exhaust noise is great. I get the hear my motor now. Turbo spool is much quicker and at cruising speeds I can barely tell its not stock exhaust. Overall this is a great quality product that I would recommend to anyone that wants to hear their motor, doesn't want to break the bank, and pick up a few numbers to boot.
