Just thought I would add my input here. I have the Dynomax evo competition on my 2012 JKU automatic now, and have about 200 miles on it so far. I did have the Dynomax VT system on it previously for about a year, but was looking for something a bit louder. And boy is it louder. Especially loud at 70 mph down the highway. I have not had to take any long trips at these speeds yet, but i am imagining that if I did, I may want to shoot myself in the head before I make it to my destination. (ok, maybe a little over the top, but you get the idea..) I may have to go back to the VT system. That one was nice in that it absolutely had no drone at all, literally none, but got a nice aggressive sound to it when you accelerate. What I did not like about that system was how it looked on the Jeep. It is a smaller muffler than stock for sure, but you can still see it as it does not tuck up in the back as well as I wish it did. Also, there is a noted change in the sound of shifting, I think related to valve in the exhaust that moves to eliminate the drone. I have an automatic, and at times when I can hear the engine trying to shift, it just acts like it is hesitating or something like the computer is having a hard time trying to decide when it should shift. At first I thought this was something that would go away with time as the ECU learned, but it did not change after a year of having this on.

Now, I also have an AirRaid intake as well, so that will change some things. If you have a stock air intake, it might not be as aggressive sounding. Just something to be aware of.

I am now considering trying the AFE high tuck exhaust. Will give the Dynomax Evo Comp a little more break in time to see if it tames down a bit, but if not, I will likely take advantage of their 90 day sound guarantee and return it. I will say that that it a great benefit to trying out Dynomax. I wish other exhaust manufacturers gave this kind of guarantee.

 

Try this as an good alternative.

Rusty's Exhaust System - JK Wrangler

RP-EXS1-JK

$159.00

 

Nice!

 

I just bought this:
Amazon.com: aFe (49-46219) 2.5" Axel Back Exhaust System for Jeep Wrangler: Automotive
edit: it looks very similar to the Rusty's system posted above...
I can't speak to the Rusty's system, but I know that the aFe is stainless SS-409. At that price ($160), it almost seems like it would be aluminum, but not sure.
I paid $228 for the aFe from AutoAnything



And I will be posting a review of the aFe axle back later this week
I spent weeks looking for anyone who had any comments on this system on every forums I could find, and came up with nothing.
Some of us have to be trail blazers I guess

Yeah, thought a bout this one at one time, but spoke with AFE who told me that it had about the same sound as the stock exhaust, which I want louder. It will look a lot better though than the stock exhaust can for sure. Let us know how it turns out.

 

If this is in fact and turns out to be true, it will be what a LOT of people are wanting.

To get rid of all that weight, and have a high tuck muffler.

 

Yeah, that is true. The guys words were "if you want some more noise than the stock exhaust then this is not for you. It is basically just a replacement for the stock exhaust once you bash it up." Or something like that. Keep us posted.

 

subscribed. Currently shopping for an exhaust

 

I've just ordered a stainless steel twin exhaust backbox for my Diesel JK. Does anyone have any experience on Diesel and will I get better sound?
