Featuring 400 cell catalytic converters, the CVF Stainless Steel Catted Downpipes will release all the hidden horsepower and torque your turbocharged EcoBoost 3.5L F-150 has to offer by facilitating more efficient airflow directly from the turbo without eliminating the catalytic converters.
You will not only experience increased power and performance but also realize a more aggressive note to the sound of your exhaust when compared to the stock catted downpipes.
Manufactured from high quality 3" T304-grade stainless steel tubing for superior strength and corrosion resistance, these CVF downpipes feature smooth mandrel bends throughout the piping to improve exhaust flow, equaling more power and better performance.
These downpipes are designed to fit the 2011-2014 3.5L F-150.

    Turbo Noise

    The down pipe install was easy and the multiple pieces helped make it a one man job. The fit and finish on this is spectacular. My CEL did come on after two days saying the cat efficiency was too low. I will see if defoulers will work. I do recommend installing with turbo adapters.

    Very well crafted! Well worth the $$$$!!

    Nice to have a company that still makes a quality product at a good price. Fit was perfect and straightforward. Love hearing the turbos spool and whistle at idle. Power and mpgs were the best part. Gained 2-3 mpgs and it clearly spools much faster.

    Best exhaust mod yet

    Got this and the turbo adapters, there is definitely some low end torque gains, and the turbo spool is now audible starting about 1200 rpms. cold start turbo spool up/down is worth it by itself in my opinion. Definitely worth the money, I took mine to a local speed shop for install, they took about 25-30 mins and $75

    Get this...don't waste your time with anything else

    I found CV Fab after a DISATROUS experience with another manufacturer. I needed both downpipes and CATS for my 2012 F150 Ecoboost and thought that I had purchased something that would work. After 6+ hours laying on my back under the truck installing it was obvious that the manufacturer had majorly dropped the ball...flanges that weren't evenly flared, fitting that didn't fit, quality that was super sketchy, etc etc...

    On a tight timeline to get my truck working, I was desperately searching for a high quality solution. I stumbled on CV Fab. I e-mailed the customer service and got an immediate response from Cristina. She was professional, knowledgeable and very helpful. She assured me that it would arrive in the timeframe I needed and would be a "bolt on" perfect fit.

    6 days later (1 day faster than promised) I got the package. As soon as I opened it, I knew this was the right choice. Super clean product in very well designed packaging. The welds, bends and fabrication were flawless. Installation literally took about an hour total and best of all, it exceeded my expectations for both quality and performance. My turbos sound much happier than they ever did with the factory downpipes/CATS.

    Don't hesitate, don't waste your time with another product. This CV Fab product is an absolute homerun and for a DIY'er that loves to wrench on my own gear, I appreciate a manufacturer that offers this level of service and a quality product. Well done y'all!
