## Overview

The ROUSH 421711 Cat-Back Exhaust is engineered for 2011-2014 F-150 trucks (5.0L, 6.2L, 3.5L), delivering enhanced horsepower and torque through 3-inch mandrel-bent stainless steel piping. Featuring polished 409 and 304 stainless steel components, it offers superior corrosion resistance and a bold, aggressive exhaust note by removing the factory resonator. Designed for all cab and bed configurations, this system balances OEM aesthetics with signature ROUSH performance and sound.

## Description

Looking to obtain the iconic ROUSH exhaust sound for your F-150, but want a more “OEM” look? Some great quality features of this exhaust are: The muffler, inlet, outlet, and y-pipes are made from high-quality 409 stainless steel to prevent corrosion and enhance durability. The tips are constructed of high-quality 304 stainless steel that have been chrome-flashed for superior corrosion resistance and durability, and are embossed with the ROUSH logo, which exit out of the side of the vehicle. The piping in this system is 3” in diameter, which is all mandrel-bent to promote consistent flow throughout. Other companies tend to crimp-bend their exhaust, which can cause restrictions and inconsistent flow. This exhaust kit is designed to work on all cab and bed configurations for the 2011-2014 5.0L, 6.2L (including SVT Raptor), & 3.5L F-150s. This includes the XL, STX, XLT, FX2, FX4, Lariat, King Ranch, SVT Raptor, Limited, SuperCrew, SuperCab, and Regular Cab models. Please note that for 2011-2014 6.2L Platinum and Harley Davidson edition F-150s, modification to the factory exhaust flange will be required. ROUSH obtains its iconic aggressive sound on this system by deleting the restrictive factory resonator, and implementing a canister-style muffler with 3” exhaust piping.

Review: Roush quality - Great sound, easy install with the right tools , I looked at Roush exhaust for a year before just saying buy it. Glad I did . Some reviews complain about in cab drone ,not really the case here sounds like exhaust should,not kackling and popping. Nice mellow tone at ildle and normal acceleration, aggressive sound with a heavy hoof . Very solid when installed and finish is good,welds and so on. Some tips for installation= raise the rear of truck at least 12 to 16 inches slide a couple jack stands under the rear axle tubes. This will help you remove the existing outlet pipe over the rear axle. From there just follow the instructions and you'll have it done in no time
Review: Overall Quality Product - Install was pretty straight forward and didn’t take very long at all if you have some sense of ability doing something like that. The only somewhat challenging aspect of having to make a cut in the exhaust to fit your Specific vehicle was almost scary how easily my saw went through the steel. You will have to own some sort of saw or grinder etc. to make that cut which can add more money one has to spend in order to get in installed. As far as results after install - It’s much louder than the stock exhaust. At times it makes strange noises when you get in the throttle. Almost a backfiring like popping noise which isn’t exactly desirable in my opinion. Has a pretty nice throaty tone to it overall. The price in my opinion is way to high for what the makeup of the product actual is. I think all cat back systems are over priced though as they are just essentially thin tubes of steel welded into different angles. Can’t imagine the profit involved when it comes to price to make vs. retail cost.

## Questions & Answers

**Q: Will this fit a 2010 f-150 (5.4l v8 supercab)? title says yes description says no.**
A: One of the pipes is cut to fit. I did my super crew with no problems.

**Q: My truck is a family vehicle. Will everyone have a migraine after an 8 hour drive? A friend of mine installed a Borla and it kills me riding in it.**
A: It's has a terrible drone at 1500-2000 rpm. I added a resonator to help cancel the drone noise. Better but if you are looking something more muted than a Borla this       
 roush set up is not the one.

**Q: I have an all black truck (wheels/bumbers/lights...everything.) Can I swap the Rousch chrome tip with a stock universal tip?**
A: You'll want to make sure the swapped tips are for side-exits instead of rear exits. The system is sold with black tips as well www.amazon.com/dp/B00N35TZAU

**Q: Someone mentioned reduced gas mileage,anyone experienced this? Is the resonator too big or the pipe too small to reinstall if the exhaust is too loud?**
A: I haven't seen any difference in gas mileage. The exhaust system sounds awesome and is a little loud but installed a 3" racing resonator to remove the droning at 1500-2000 rpm.  The factory resonator will not fit the new system.   Hope this helps

### ⭐⭐⭐⭐⭐ Everything as expected
*by C***N on August 5, 2022*

I had been looking at this exhaust for awhile. When I decided to purchase it, I found it on Amazon from this seller for well over $100 cheaper. Delivery was estimated at 7 days, I received it in 2. The package did not come with formal instructions, instead it came with a website to go to. I didn’t use the instructions as it was pretty simple to install this exhaust after removing the original. This Roush exhaust sounds great on my 2014 F-150 w/ a 5.0.
