My mechanic told me that the only modification which actually does give performance and efficiency boost is an exhaust system. He thinks everything else is worthless.

No I don't, because the tree hugging hippies are stirring the government up more about emissions than they are mpgs. Don't believe me? Take any new diesel pickup with all the new emissions crap that they have on it and drive it for 1,000 miles and see what your mpgs are...now replace it with a full turbo back straight piped exhaust...I guarantee 2mpg gain with doing nothing else and not changing your driving habbits. If the manufacturers were more worried about mpgs than emissions you wouldn't have that big of difference. Now add a intake and tune to that diesel and you will see even more of an increase. I use diesel as the example here for 2 fold...1 they are notoriusly WRONGFULLY labled as being dirty and poluting, and second they respond more to being opened up than gas motors do...but that isn't to say that everything coming out of the factory with a gas motor is as efficient and has as much out put with the stock equipment as it can get. If you believe that, you sir are the blind one here.

And he is mostly correct. Try this once...stuff a ping-pong ball a few inches into a snug fitting hose and then blow on the hose untill the ball comes out. Now do the same thing only this time fill the hose from the ball to where you are blowing into it with cotton balls. Which one do you have to work harder to get the ball out of? The plugged hose or the free flowing hose? Works the same with a car, the more free flowing the exhaust the less the motor has to work to push it out and the more effeciently the motor can produce power.

Dynos don't lie people. Sure you will see MUCH more gains out of an aftermarket exhaust system if there is other motor work done, but that is just because power adding equipment all works together in a properly running system.

I agree 100%. Where can we view the test results as well as all the supporting data?

Any of the exhaust companies have dyno results with stock exhaust and with there exhaust...and to head you off before you start, it would be illegal for them to report inaccurate dyno results.

Here is one from magnaflow...

You wanted to see a dyno, there you go. I am sure you will say "well sure that is straight from magnaflow"...well if you knew anything about performance vehicles you wouldn't be saying stock is as good as anything.

If that isn't enough you could youtube it. There are plenty of independant shops that have youtube vids of before and after dyno runs. Unfortunatly we don't have a dyno yet at work or I could just take a truck and dyno it stock and then swap the exhaust and dyno it with only exhaust added.

If MagnoFlow say it works it must! How about an independent test? As I stated earlier, you are just blindly listening to marketing. If what you say is true, show me independent testing and data.

Don't take this personally, I'm not attacking you, just your belief that marketing is fact. Most statistical data can be used to tell whatever story you want.

Let's take a look at your chart. How often is anyone running over 4k RPM in a JK for a prolonged period? I'd like to see the data below 4K where most of us live in the real world. From that chart, it's flat at best and possibly worse.

You want independant? Do what I said and go youtube it. If stock is the best there is why would anyone ever change it? Just because of marketing? Heck, why doesn't Dale Jr just use a factory Impala muffler...I mean come on there is no improving over factory!

You are telling me that I am blindly believing marketing and not giving me any infor to back your side! I gave you the ping-pong ball example, I have you the diesel example...what more do you want? I don't have a dyno at our shop YET. Yes, thats right I work at a performance shop so I know the benifits of aftermarket exhaust...where are you coming from? $10 says you sit behind a desk shuffeling paperwork all day.

I'm done with this, it's obviously not possible to have an intelligent discussion with you. "Working" at a performance shop gives you no credibility, for all we know you sweep the floors. I don't care about your useless ping pong balls and what any idiot can post on You Tube. I looked at your diagram and it supposedly shows gains that occur beyond 4K RPM. No one drives a 3.8 at that RPM for a constant amount of time. We are talking about Jeeps not ricers.

Oh and Mr. Performance expert, stock cars don't have mufflers. Have a nice day!

So you are just going to come in here and rip on any type of information I can present to show my case, all the while without presenting anything to support your case, and then you have the gahl to say that I can't have an intelligent discussion? Wow, have a good one!

I drive my Jeep over 4000 RPM all the time. Stop trolling, daggo.

I went with the Rugged Ridge with Gibson slash cut tips and like it because we wanted a decent SS direct bolt on no modification system without much of an increase in sound volume. Once you decide what type of system you want talk to the dealer as was previously mentioned, but they may want to talk you into the Mopar system which is understandable. Search the Forum for more info. on why members chose the systems that they installed and what they were looking for; performance, sound, appearance.
I'll quote myself on this one. A lot of controversy on something as simple as a cat back exhaust system. I'm sure that some mods aren't too useful but we do them anyway for a variety of reasons. And, not all systems are "obnoxious". Obviously no matter what you do you can only move a brick so fast, so when I want speed and performance I go to my M3. Putting a dual bolt on relatively quiet SS system on my 10 Rubi, even if I only gain 2% performance is worth it because A. dual exhaust looks cool on any vehicle and B. SS dual exhaust looks even more cool with an off road bumper. So, keep adding mods that you like and enjoy your JK's.
