Highlights:

Massive Reduction in Backpressure
304 Stainless Steel Construction
3" Diameter
Increased Horsepower and Torque Output
Bolt-On Replacements
Will Require Custom Tuning

Vastly Improved Power without Rasp

The most restrictive part of your 2011 to 2014 EcoBoost's exhaust system is its downpipes and Y-pipe. Their small diameter and inefficient factory catalytic converters choke your 3.5L EcoBoost V6 off from making more power, especially if you've stacked on other modifications and tuning. Stainless Works' catted EcoBoost downpipes free up much of those restrictions and greatly reduce back pressure to give your powerful truck a massive improvement in horsepower and torque output, especially in conjunction with other modifications and aggressive tuning. Stainless Works' downpipes are a perfect way to push your truck's EcoBoost motor to its absolute limits and get the power and vicious sound you'll need to conquer the streets or off-road trails.

Includes High-Flow Cats and Y-Pipe Connection

The kit consists of two catted downpipes and Y-pipe connector for your cat back that measure 3" in diameter. Stainless Works carefully mandrel-bends all of this kit's exhaust tubing to ensure smooth outflow and to maximize power gains. Further reducing back-pressure are two high-flow catalytic converters that are are far less restrictive than your stock converters and also help avoid a raspy, whiny exhaust note that's common on off-road downpipe kits. This whole system is made out of high-quality 304 stainless steel that's resistant to corrosion and discoloration in any climate. These down-pipes are bolt-on replacements for stock and can hook up to your factory cat-back and stock-sized aftermarket cat-back systems.

2013 XLT SuperCrew 4x4 Ecoboost

READ! This does come with directions, Thank You SW. Read them! Good Addition to my truck. Follow the instructions. I've done almost every bolt-on to my truck. Had this done with a professional. Use a lift! If you are going to save your old down pipe, you will have to remove transmission crossmemeber. (I save all my parts to go back to stock for warranty) Drivers side Turbo is the hardest one to get to. Once you complete the install, drive your truck for 30 minutes...or longer. You will have an exhaust leak. I had one, along with many other I read about in the Forums. Lift truck back up and tighten. Found another 1.5 days later. Fixed it. Sounds great with 3.5 exhaust. Really hear the turbos. Don't be scared to do this install it takes about 2-3 hours on a lift. But, don't underestimate it either. Overall performance off this one part, I can't tell you because I also installed Livewire TS tuner.... NEW TRUCK over all!

SW makes a great product! These downpipes were a great addition to my truck. The quality of the stainless steel is top notch! To test the quality of stainless steel just sick a magnet to it and if it sticks your quality is pretty poor. I assure you that no magnet will stick to these SW downpipes. I highly recommend these downpipes and as always big thanks to the Lou and the folks at Stage 3!

2013 F150 King Ranch 4x4 Ecoboost

Rating 4 out of 5 because I had to re-tighten the exhaust to the turbos twice due to exhaust leaks and the y-pipe collector sits too close to the side of the transmission crossmember and causes and additional vibration at certain rpms. Will likely have to go to an muffler shop and have them re-tighten or maybe add a hanger to prevent the collector from vibrating against the crossmember.

Noticeable reduction in back pressure, may require a tune to compensate. O2 sensor location should be re-engineered. Some difficulty with installation.

I installed this with the SW chambered exhaust system and did the down pipes on the first weekend and the catback on the next weekend. I'm not a mechanic by trade, but know enough to be dangerous. That being said, I installed these down pipes by myself in my garage with just the front of my truck on hack stands. I'l have to say that the instructions suck. Because of the bad instructions, it took forever to take the stock down pipes off. I finally found a video online of a guy installing that down pipes on a 2015 F150. From that video I found ot that I didn't have to take off the front drive shaft. Good thing because that was what I trying to figure out when I found that video. The other thing I found out was the location of all the O2 sensor plugs. 4 in total. Also the tools that would make removal easier. I ended up cutting my down pipe because one of the bolts that hold on the transmission mounts could not be loosened which also holds one of the hangers. Once you get the stock down pipes off, the install is much easier. Just make sure you take your time to adjust all of the pipes and getting it to fit before tightening everything down. I used my high torque impact to tighten the flanges and have no leaks. This is a great product and it fits like a charm. All pipes fit with no touching of any parts. It mattered to stock catbacks with no issues.

This product was easier to install than the stock equipment was to take off. The sound is good, and definitely improved the performance of my truck.

Asked by: Bradley - 7/26/2014

It will fit with the aFe kit and any other cat-back kit designed to fit the factory mid-pipe.

Will this work with the Afe cat back exhaust?

I hear a lot more about solo catted, but to me the SW catted seem better built. Does SW use quality cats? I can't decide between solo catted or SW catted. If theres nothing I'm over looking, I would have to say the SW are a better downpipe. What is your opinion on them?

What size (inches) is the exhaust pipe down stream of the Y?

Will a truck with this kit installed still be able to pass emissions since it still has the CATs?

if installing catted downpipe on a stock tune or mild tune, with the O2 sensors, will it pass emission? What performance gain might be seen from installing the without changing the tune?

What about an emissions test that is not OBD-II? Where they just hook up hoses to the back of the exhaust.

Can this downpipe get shipped to a CA address? Thank you, Bruce

Would this have capability to fit the 2014 F150 V6 3.7L? Maybe with minor adjustments?

Does your company make a Y-Pipe for the F150 3.7L V6?

Hi, I already have a 4" cat back exhaust, intake, and Sct live wire tuner with 5 star tunes. Is there a rough estimate on what gains I could expect to see from a new down pipe?

Will this down pipe work good with the chambered exhaust I think the the s- tube exhaust is to loud for me not sure witch one to go with ?

In the description, it mentions that the Y-pipe will require custom tuning in order to avoid engine damage and avoid CELs. Can you explain why this alone without tuning cause engine damage?

With a tune, will this downpipe pass emissions? (MA specifically)

Is there ANY benefit to doing something like this if I run regular gas? Yes I have a tuner and yes I will pay to have it recalibrated, but don't want to spend the extra $20-$30 every fill up for premium.

Do I need defoulers with this down pipe?

I have a a tune on my truck from a company that can’t retune now unfortunately. But my cats are rusted out and need new ones but I’m scared to sense I can’t retune. Am I able to swap them with out retuning?
