This cat-back exhaust system improves engine performance and durability by boosting horsepower and torque. Its technologically advanced, Mandrel bent tubing and straight-through muffler allow the exhaust to flow more freely through the system.


Features:

  • Improves engine performance by increasing horsepower, torque and fuel efficiency and decreasing exhaust gas temperature
    • Mandrel bent tubes allow for unrestricted airflow by maintaining the same diameter through every curve
      • Unrestricted airflow decreases back pressure ("exhaust turbulence")
    • Straight-through muffler has a stainless steel perforated core that runs straight through, end to end
      • Layer of stainless steel wool insulates the perforated core to absorb noise, shield high exhaust temperatures and prevent blowouts
      • Contains no baffles, chambers or louvers that restrict airflow
  • Signature sound is deep and throaty on throttle but quiet inside the vehicle
  • All materials made with 100% stainless steel
  • Clamps and hangers included for installation
  • Lifetime warranty

Specs:

  • Tubing diameter: 3"
  • Muffler dimensions: 5" tall x 8" wide x 24" long
  • Tailpipe diameter: 3"
  • Tip diameter: 4"
  • Number of tips included: 1
  • Single exhaust system
  • Rear side exit position

The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter to the tailpipe. MagnaFlow systems have Mandrel bent tubes that allow for unrestricted airflow by maintaining the same diameter throughout every curve. This curvature leads to decreased back pressure.

MagnaFlow mufflers have a stainless steel perforated core that runs straight through the muffler, end to end, with no baffles, chambers or louvers that restrict airflow. A layer of stainless steel wool insulates the perforated core to absorb noise, shield high exhaust temperatures and prevent blowouts.

Together, the Mandrel bent tubes and straight-through muffler increase horsepower, torque and fuel efficiency and decrease exhaust gas temperature. MagnaFlow's signature sound is deep and throaty on throttle but quiet inside vehicles. All materials are made with 100 percent stainless steel. Clamps and hangers are included for installation. It includes a lifetime warranty.

Review from a similar Catback Exhaust in Exhaust Systems


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.

All is very well. No problems of any kind. Still enjoying the sound and the look.

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!

So during highway driving the drone is at a minimum? I have kids too and we take a lot of family trips. My concern is the drone. thanks,

Response to B. Kallan~ Highway noise is quite bearable, unless youre knee deep in your pedal. Going uphill it will be much louder, as it will with any acceleration. Constant highway speeds will result in a nice, mellow sound. Hope this helps!

Review from a similar Catback Exhaust in Exhaust Systems


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.

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.

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.

Review from a similar Catback Exhaust in Exhaust Systems


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.

Review from a similar Catback Exhaust in Exhaust Systems


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.

nice and growly sounding, helpful tip spay some wd 40 on ends before fitting together, helps to slide the parts together easier.

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.

  • Recommendations for Exhaust Sound on 2002 Ford F-150 Lariat 5.4L V8 Triton Short Bed SuperCrew
    Adding an exhaust tip like the MagnaFlow 4" Exhaust Tip - Stainless, Clamp-On for 2-3/4" - 3" Tailpipe # MF35212 to your 2002 Ford F-150 won't drastically change the sound but it will make a difference. It will make your exhaust louder because the cone shape is like a cheerleader megaphone to amplify the sound waves so it will sound a little more aggressive but it won't really change the depth of tone much. If you want louder this will definitely help. If you want the deeper rumble,...

    The MagnaFlow 4" Exhaust Tip - Stainless, Clamp-On for 2-3/4" - 3" Tailpipe # MF35212 will make your truck louder, but there are other options to make it much louder if that is what you are seeking.

  • Horsepower and Torque Gains From Edge Evolution CTS Programmer # EP85250 on 2002 Ford F-150
    I contacted our representative at Edge and he informed me that they are getting gains of up to 15 horsepower and 20 ft/lbs of torque added to a stock Ford F-150 using the Edge Evolution CTS2 Programmer, part # EP85450. The gains on your truck could vary slightly. In addition to a programmer, adding exhaust and an aftermarket intake will also help in performance gains on your 2002 Ford F-150. Adding an intake and exhaust will allow more air to flow to engine and air to flow more freely...
