Great Sound and Extra Performance for your F150

Diamond Eye has been in the truck exhaust game a long time, and they've used their knowledge to come up with an awesome 3.5" Cat-Back Exhaust System that can give your F150 a nice boost in power, fuel economy, and a great sound. Diamond Eye's 3.5" Cat-Back Kit features a stock-style single-exit design that keeps your truck looking clean and mean while it produces a big, aggressive rumble that will instantly catch everyone's attention. Diamond Eye's large tubing, unique muffler, and more efficient manufacturing enables this system to bring new life into the 3.5L EcoBoost V6, 5.0L V8 or 6.2L V8 of the F150s.

3.5" Diameter Mandrel-Bent Exhaust Tubing

This aggressive Diamond Eye Cat-Back Exhaust Kit bolts on right in place of your truck's factory exhaust system in an easy installation that can take less than an hour. The Diamond Eye kit features 3.5" diameter tubing that's all mandrel-bent to help improve exhaust outflow and reduce restrictions. The kit is made out of 409 stainless steel and comes standard with a high-performance muffler that produces a deep, throaty, and aggressively loud tone to give your truck a great sound to go along with all that power. The kit comes with both hardware and detailed instructions for installation.

Fitment: 2011, 2012, 2013, 2014 Ford F150 3.5L/5.0L/6.2L - All Cab and Bed Lengths.

Tip sold separately: this kit does not come with an exhaust tip.

2012 F150 Ecoboost

I ordered this and received it in 2 days. I also ordered a resonator to add to this system. Installation was fast, even with modifying it to fit with the resonator. The stainless system is very well built and very good quality. The only thing I wished they would have added with the kit was a flex pipe. That would have removed some of the vibrations from the muffler. The one big negative I have found is that the exhaust was extremely loud. Drone in the cab is almost unbearable. I first removed the resonator which helped some, then also removed the muffler which helped a lot. Right now I am running straight pipes. I really expected the muffler to actually do something so I am taking off a star for that. But the quality of the system and the fitment was spot on so that is why it gets 4 stars.

I just installed this exhaust on my 2014 f150 5.0 it was really simple. All you need is 2 jack stands it your gonna install your self to help hold in place. The sound is amazing it not to loud cruising but if you want to kick it down then it comes alive. It will definitely make people turn there heads driving by

2013 f150 5.0

install was easy, but the exit of the exhaust came out under the box so I used the extra length of pipe to extend the tailpipe out far enough. its also very loud had to install a resonator to get rid of bad drone in the cab. it did give it lots of power

Have a 5.0 2014 150 with a 3.5” diamond eye cat back and AFE shorty headers. Will the AFE mid pipe fit both? I’d like to complete the full exhaust system.

Asked by: Andy - 1/19/2018

aFe's Y-pipe should fit both, since it's designed to fit with the stock cat-back or a stock-replacement cat-back. We haven't tried it personally, so we can't guarantee how will it will work out, but on paper, it should work.

Will this kit fit my 2011 FX4 crew cab long bed?

Asked by: Sean M. - 7/12/2016

Diamond Eye includes an extension pipe that allows for the exhaust system to fit on all F150 wheelbase sizes, though I believe that 157" wheelbase trucks will require some trimming of that pipe, since it's built for trucks with 163" wheelbases.

Will this 3.5" kit fit my 2015 5.0. Looking for deep exhaust with little drone. Torque loss?...

Asked by: Dan - 2/6/2016

This kit will not fit the 2015 F150s. Unfortunately, Diamond Eye does not yet have a variant of this cat-back kit for the 2015-2016 F150s at this time.

How loud is this exhaust,on the 5.0, on a scale from 0 to 10?

Asked by: 14f150 - 8/26/2015

If 0 is stock and 10 is the Flowmaster Outlaw Kit, then the Diamondeye is a solid 4.5. Noticeably louder than stock, but not excessive.
