Magnaflow Exhaust Review 17143

So I decided to try out this Magnaflow pipe for my 2014 jeep wrangler unlimited sport s.

This is a high clearance model that lets out before the rear axle.
Magnaflow 17143 Performance Exhaust Kit : : Automotive

^^^^ on amazon for 420$$ (where I ordered mine from)

What initially drew me towards this pipe was a mixture of the price, and that it lets out before the rear axle. Not because I off road a lot and need the clearance, but because I have never been a fan of the stock exhasut hanging down all big and ugly below the bumper.

What I wanted out of an Exhaust pipe. Going into this I wanted to get something that would increase performance, give me better milage, (even if its one mile per gallon) and at most, give me a good throaty aggressive sound.

^^^^^^ two of the videos I watched to try to get a sense of sound

Sound I think is the biggest thing when buying a new pipe. No one wants the dreaded "drone" and you want it to be loud but not like the shitty honda civic being obnoxious. I don't want to make a video to try to help you get a sense of the sound because cameras just can't represent the sound well enough and until you hear it in person… you just don't know, so I will try to give you an idea in words.

I should start out by saying yes, I like it.

who am I…

Im a 22 year old guy who lives in a neighborhood full of young families with young children. in 10 years I see my jeep looking aggressive but still a DD so not too extreme. I have no kids. engaged.

I like making a little noise but I'm at that point where it is time to grow up a little and I don't want to be pissing off all of my neighbors and waking their kids….That is why this pipe works for me.

Is it louder? yes!
to loud? for my situation… almost..

What I mean… If it where any louder, It would be too loud. But it is just right for me right now.

It has a great throaty sound and it sounds like a truck, not a rice burner.
In a way it is as loud as you want it to be. If I drive in a way to save as much fuel as possible its not THAT loud. The more gas I give her the louder it is. If I accelerate slowly, its not loud enough to piss off my neighbors, If I gun it…They WILL be pissed. That is why Im enjoying it. Its the best of both worlds.

On the highway as your speeding up its loud, one you reach your speed though and you through it in 6th to coast its almost silent, no drone. If you start going uphill and you lay in the gas or down shit she starts growling again, then yo hit flat ground and its quite again.

There is a noticeable vibration with this pipe but by no mean out of control. You just feel it in your ass.

Will I keep it for ever? probably not. Once I have a car seat its probable gone.

I heard these system get louder over the years, we will find out!

I have had it on for a week.


My wrenching experience consists of small engines in high school and construction for a year.
Me and a friend were able to get it done in about 4 hours.
you will need a socket set, vice grips, pry bar, wd40, and patience. It was quite a wrestling match getting the rubber hangers off the old pipes, specially since it was about 30 degrees in my garage. We had to take the skid plate off to get the old pipe out. I read you don't have too but we gave up twisting and tugging on the pipe. once you take the skid plate off its cake.

Would I suggest it to a friend? hell yea. its got a great tone.
performance? I can feel a slight gain…slight… its a jeep though I didn't buy it for that.
gas? my average went up 1.5 ish at best, then the temperature dropped to 17 degrees so I can't really give you a good answer.
sound? Love it. Manly big balls sound when accelerating hard. Quite growl when cruising.
It sometime does that sound I can't really explain when decelerating in gear.. like bla bla bla bla blaaaaa grrrrr pop pop. But it doesn't do it too loud and annoying. its tasteful.
For the price I think its awesome! specially if you install it on your own.
father jeep bonding time is healthy.

I really hope this helps any one looking! I think its cool and different and turns heads. feel free to ask any questions I will do my best to respond!

Great review, thanks for that!

I do have one comment and one question...

In my experience with Magnaflows they actually tend to mellow over time as opposed to get louder. This is generally a good thing.

Do you have any drone in the cabin around 2000-2200RPM? This seems to be a common drawback to custom exhausts.

If it mellows out then maybe I will keep it for even longer!

about the drone…
Im not sure how to answer this because I don't have much of a reference point and Im not fully sure what people mean by this. At 2000ish rpms on flat ground (just maintaining speed) I find the sound to be to be reasonable to quite…. at 2000ish going up hill in 6th it is loud aging, but not so loud I don't enjoy the ride.
I compare it to my buddys old mitsubishi evo. this thing on the highway was so loud you had to yell to have a conversation.
if what it does at this speed is considered a drone I would consider it a very mild drone. I was just driving at 75 today and still like it! its even fiancé approved!
with the 6 speed transmission once you get up to speed its pretty quite.
Hope that help bbermann!
for 400$$ on amazon I say shit, buy it and try it.. if its too loud, return it! amazon is great for that, they make it easy.

Thanks for your review. I'm purchasing one as we speak. I hope it's up to my standards in loudness while still bettering my mpg, even if it's 1 mpg!

Awesome! it will be interesting to hear another opinion once yours is installed! Its been a few weeks and I'm falling more in love with mine! its a little lout going 70-75 for my taste but I rarely am on the the interstate. I just wish it wasn't winter so I could have the top down and doors off to really hear her growl! hope you enjoy!

I'm looking at the black dual exhaust from the same maker... The look is awesome! Wonder if the sound is different? I too have been looking for a way to have a more manly sound.

Thanks for the review, I'm glad I found it and you like it since I just blindly bought this exhaust for my wifes jeep from a buddy at work. For what I paid I guess I scored even if the wife ends up not liking it.

Just bought this 2 weeks old from a guy whose wife said it was too loud for $80. Just installed it yesterday and so far, so good. Has it mellowed over time? I really like it and my 16-yr. old daughter loves it!

I've had the Magnaflow 17143 on my '14 JK for about 2 months now and I couldn't be happier with it. I really think it has the perfect amount of growl without being too loud and the quality is second to none. One more perk is that it is practically invisible on the Jeep and it deletes the obnoxious rear muffler. If your thinking about a new exhaust just buy this, you won't regret it.

How would the sound be on the highway, say 2700-2900 PRM cruising under load from a small trailer? 1100lbs-ish.

Seems like an awful lot for some pipe and a muffler...if you like it, more power to you.

I've had flowmaster on all of my jeeps and love the sound.
