Deep Rumble with Noticeable Sound Gains

The Stainless Works Chambered Cat-Back kit for the 2011 to 2014 F150 EcoBoost trucks is one of our most popular kits for those turbocharged, direct-injected trucks. The Chambered kit adds on a deep, mellow, and noticeable rumble to your truck's exhaust note without a ton of drone or turbo whine for a crisp, deep sound that will turn heads instantly. Along with the awesome sound, the Stainless Works Chambered kit adds on some excellent horsepower, torque, throttle response, and fuel mileage gains thanks to its larger and more efficient exhaust tubing. The EcoBoost Chambered cat-back kit easily installs in place of your factory cat-back system for hassle-free sound and power gains.

Legendary Quality and Efficiency

Each system is built using 3-1/2" mandrel-bent exhaust tubing that has reduced back pressure and restrictions over your factory crimped exhaust system. The smoother tubing and more efficient muffler allows for improved exhaust outflow for power gains. Stainless Works manufactures the entire kit out of high-quality 304 stainless steel that's resistant to corrosion and discoloration in practically any climate. Each system hooks right up to your truck's factory mid-pipe, Stainless Works' EcoBoost Catted Downpipes, or their Off-Road EcoBoost downpipes without modifications. The Chambered kit comes with your choice of a black or polished 3-1/2" slash-cut exhaust tip that exits in the OE exhaust location. Choose your exhaust tip option from the drop-down menu above.

This cat-back exhaust kit deletes your factory resonator for a more aggressive tone.

Wheelbase Fitment: this Stainless Works cat-back will only fit trucks with up 157" wheelbases and will not directly fit trucks with 163" wheelbases (SuperCab with an 8' Long Bed). Call 623-434-5277 for more information.

2013 F-150 Lariat Screw Ecoboost

If you are wanting to add high quality exhaust to your Ecoboost, you have to buy this Cat Back Exhaust from Stainless works! Even though it's a V6 the exhaust unleashes the sound of the spoiling turbo while having no drone what so ever. At WOD you can hear a decent roar (even though it's a V6) and you can hardly hear anything while the truck is cruising on the highway or stopped at a light. Great buy and great recommendation from Lou at Stage 3.

Overall great exhaust system.. Got it with the black tip and couldn't be happier with the sound and performance over the stock system.

2013 F150 FX2 Screw

Great fit, finish, and sound. only bad par was ordered the black tip and got the wrong clamp. It came with a 3.0 needed 3.5. No big deal though love the exhaust. Would have received 5 stars if all parts were there.

Installation took a little longer than expected, but not that difficult. Nice sound, but the loss of back pressure kills the bottom end performance. You'll need other enhancements like a tuner. Coupled with an aFe intake I did pick up 2-4 mpg depending upon my driving.

Deep throated sound. Noticeable in cab over stock, but not overpowering.

I recently purchased the hellwig rear sway bar. During the hellwig installation video I found online they made the comment that an aftermarket exhaust would not fit with the sway bar. Will this cat back fit with the rear sway installed or will it require custom fab? If not, will any of the other cat backs you list fit with it?

Asked by: Caleb Badley - 3/4/2016

To be totally honest, we don't sell the Hellwig bars, and we're not 100% percent familiar with them. However, it's my understanding that you can use cat-backs up to 3" in diameter that exit in the factory location without any issues or with only mild modifications made to the hangars and brackets, so the Stainless Works Kit may be fine. That being said, your best bet would be to call Hellwig and see if they have a list of compatible cat-back kits.

With stainless works chamfered exhaust will there be a big power loss when no tuner is being used? And how much louder is it then the stock exhaust?

Asked by: David - 2/7/2016

You generally won't see a difference in power and performance with this kit, if it's not used with a tuner. The kit is noticeably louder than stock, put its not too overpowering.

I want an exhaust that flows better for more power but do not want a loud exhaust. Should I go with the chambered exhaust or the S type?

Asked by: Robert Dorough - 6/10/2015

Chambered, but a cat-back exhaust alone is not going to provide a ton of power, even a large, free-flowing kit.

What's the difference between the chambered and the s pipe from Stainless Works?

Asked by: kazoo 154 - 12/30/2014

The Stainless Works Chambered Kit comes with a chambered muffler, while the S-Tube Kit comes with a Stainless Works S-Tube muffler that has a straight-through design. The Chambered system is a bit less than aggressive than the S-tube.
