The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter back to the tailpipe. MagnaFlow systems boast mandrel bent tubes that allow for unrestricted airflow by maintaining the same diameter through every curve. This consistency in diameter decreases back pressure in order to boost power.
Each MagnaFlow performance muffler has a stainless steel, perforated core that runs through it - end to end - with no baffles, chambers, or louvers that restrict airflow. A stainless steel wool layer insulates the perforated core to absorb noise, shield against high exhaust temperatures, and prevent blowouts.
Together, the mandrel-bent tubes and muffler in this system increase horsepower, torque, and fuel efficiency.
MagnaFlow's signature sound is deep and throaty on the throttle while remaining quiet inside your vehicle. All system components are made with 100-percent stainless steel to resist corrosion. Clamps and hangers are included for installing onto the OEM exhaust system. MagnaFlow provides a lifetime warranty on all stainless steel exhaust systems.

Installation was easy, perfect fit, sounds great and engine roars! Thanks etrailer for the great customer service and MagnaFlow for a great product!

Have to say that I was a bit skeptical at first, as I don't know anyone that has installed this particular kit. After installation, I am pleased to report that it has exceeded my high expectations. Kit came complete with everything needed to install (less the flange bolts). Initial sound was excellent...not too loud that it bothers the kids while they're sleeping in the car, but deep and loud enough to turn some heads. Excellent experience dealing with Etrailer as well. Will not hesitate to do business with them in the future. Thanks again for the super fast shipping and excellent customer service!

My Magnaflow cat back exhaust system on my 2016 VW GTI gave me more of the sound I wanted for my little sports car, and it looks so much better than the stock exhaust system. Meaning: the stock muffler, which shows horizontally at the rear of the vehicle, looks like an afterthought, just a metal can. The muffler on the Magnaflow is hidden in a pocket near the center of the undercarriage, so it doesn't show at all. What is visible at the rear are the dual stainless steel pipes. In addition, the exhaust tips on the Magnaflow are larger in diameter to accommodate the larger diameter pipes, and therefore look more aggressive. I am very satisfied with the setup.

The exhaust system fit perfectly, sounds great, and looks stylish. The exhaust tone is not overly loud, yet sounds much more powerful than the stock system did.

Hardest part of installation was getting the truck high enough off the ground to get the factory exhaust over the axle. The new system was relatively easy and fit perfect. The spare tire does not fit underneath with this kit installed. I put a Tire Buddy in the bed to hold the full sized spare. The heavy duty factory receiver hitch is not in the way. System has a mellow purr that should be street legal everywhere yet is semi-aggressive. No blatting or popping. Chrome tips seem to always get black with soot and need to be cleaned often. This is a premium system and should last the life of your truck. It is well supported and doesn't vibrate. I highly recommend it. If Chevy had this as an option they would sell lots more trucks.

Bought the magnaflow exhaust for my 2015 GMC. Everyone says how great it sounds. Price was good and easy to install.
by: John Porter06/27/2016
Very good performance and sounds installed myself in driveway in under 45 minutes. service was great from e-trailer.
by: Tom K.08/05/2017
I am well pleased with the system itself. This was actually a replacement under the warranty, and the previous system lasted seven years, here in the rust belt. Only complaint was the necessity of returning to manufacturer for inspection prior to receiving replacement. That meant my truck was down for about a month.

Great customer care and service from Chris and the Etrailer employee's. Got back to me to let me know of a item was back ordered from a manufacturer, didn't try to over sell me on products, asked what I'd like to do. Helped me make changes to my purchase that I needed right away. Two days later they now have my business shopping loyalty from here on out. I can't thank you guys enough.
by: lothar02/14/2017
nice and growly sounding, helpful tip spay some wd 40 on ends before fitting together, helps to slide the parts together easier.
by: Len. J09/23/2016
Product nice. Fit could be better for trans am. Tail pipes don't show. Had to make extensions. Works ok now
by: John Porter05/11/2016
I believe it is the best exhaust on the market for this application. only thing is the exhaust tip needs bent down more as it touches the body and will melt plastic.
by: Michel 10/28/2020
Nice addition, not too loud and yet good rumble. Easy installation and would recommend it.
by: Phil B.07/04/2010
Not a great fit on my 2009This kit sounds and looks great, but the three bolt cat flange didnt fit my truck, it required machining to spread the holes further apart, just a heads up my honda ridgeline was built in june of 2009 and the install took 5 hrs because of this issue, however when finished it sounds and looks great.
by: Ray J05/28/2009
Not a direct FitSounds good but had to modify rear brackets and drill holes in the frame to install on 09 F150 crew cab..not impressed with fitment or installation time..modification time caused loss of profit..
by: Mike07/22/2011
The MagnaFlow exhaust looks and sounds awesome. Not only that but the stainless steel construction and lifetime warranty gives me peace of mind.

- Recommended Tuner and Cat Back Exhaust for 2016 GMC 1500 5.3LOn your 2016 GMC Sierra 1500 with 5.3L, the addition of cold air intake and programming chip won't change the life expectancy of your catalytic converters or the oxygen sensors. The oxygen sensors will have the parameters changed slightly by the tuner, but nothing that will be noticeable in life expectancy. For your vehicle, we unfortunately don't have a confirmed fit at this time for a cold air intake system. For a tuner, I recommend the Edge EvoHT2 Hand-Held Performance Tuner # EP26040...
view full answer... - Best Way To Increase Horsepower And Torque In A 2017 GMC Sierra 5.3L V8The best way to not only maximize but increase horsepower and torque on your 2017 GMC Sierra 5.3L V8 would involve installing a cold air intake, performance exhaust system, in addition to a performance chip tuner. Using these components will allow your engine to breath better and perform at it's peak output which will increase not only power but also fuel efficiency. For a cold air intake compatible with your vehicle, I recommend using the Airaid MXP Cold Air Intake System part # AR200-285...
view full answer... - Will a Cat-Back Exhaust System Fail State Emissions TestingThe MagnaFlow Cat-Back Exhaust System part # MF15278 while installed on a 2017 Chevrolet Silverado 1500 with 5.3L V8 engine would still pass state emissions testing. The critical components in regards to emissions is the catalytic converters and since this is a cat-back system meaning it installs behind the factory catalytic converters, there will not be any problems not meeting state regulations. I have a similar system installed on my vehicle in a state that also requires emissions testing...
view full answer... - Options for Increasing Horsepower and Torque on 2018 GMC Sierra 1500 with 5.3L V8 EngineThe best overall setup for increasing the horsepower and torque on your 2018 GMC Sierra 1500 is with a combination of components consisting of a performance tuner and exhaust system. Starting with the tuner for your Sierra 1500 I highly recommend the Edge Gas Evolution CS2 # EP85350, which features a full color 2.4" screen for easy parameter viewing, pre-loaded performance tests to provide you with road stats/times, and is made here in the USA. Om your Sierra with the 5.3L engine Edge...
view full answer... - What Kind of Increase in Gas Mileage Would a Cold Air Intake, Exhaust System and Flashpaq Give Me?It's impossible to give you a 100% accurate answer on this because there are so many different factors that gas mileage is affected by and when you pair them all together it isn't just as simple as adding the expected gains together. It should also be noted that over time, your vehicle's fuel efficiency goes down so the numbers I'm going to give you are based off the EPA estimates on a similar truck that is fresh off the lot. Now, I'm going to try to put on my math hat and give you a general...
