The results are in.. I’ll keep this as short and sweet as I can..
Test and configurations were made to my 2007 Jeep Wrangler 4D Rubicon..
1st. Dyno run
Bone Stock = 180.7hp / 215.8tq

First we installed a Magna Flow True Dual Exhaust system keeping the stock catalytic converts in place..
2nd. Dyno run
Dual Exhaust System = 189.6hp / 222.5tq

Then we removed the dual system and re-installed the 2 into 1 collector and just ran a single back to a Magna Flow 6” x 18” muffler and then straight back..
3rd. Dyno run
Single Exhaust System = 194.3hp / 231.3tq

Obviously the Single System yielded much better results.. That is what stayed on.. And let me tell you the Sound is awesome..

Now the easy stuff AEM Brute Force Intake System.. Very Clean install..
4th. Dyno run
Single Exhaust System with AEM intake = 202.1hp / 234.6tq

Last but not least.. We installed the Jet Performance Stage II chip.. My initial thought process on this one was I wasted my money.. But the Dyno tell the truth..

5th Dyno run
Single Exhaust with AEM intake and Jet Performance Stage II chip

Final Results = 213.9hp / 243.3tq
Overall Gains = 33.2 HP / 27.5 TQ

Maybe to some this was a big waste of time but what the heck free use of a dyno and some spare time and some great Manufacture support.. Take these results as you may..
I will work on getting some pictures up on the exhaust relocation and intake install…I will also work on getting the dyno slips posted up.. Thanks Jay

Edited --- All number were off an estimated 18hp and 15.5tq... After we calibrated the dyno, this is what we discovered.. I have correct my numbers to show the correct gains..

 

you can see it in the pics he included in his post, it is right beside the emissions canister

 

We'll see if this picture works..

 

30+ hp gain.....bottom line....can you notice a difference from stock? performance, fuel economy?

let us know......

 

Thanks, this is great news and jeep got a good gain.

I would like to know how your MPG has been affected.

Please post back after a couple of tanks......

 

Also, What kind of a volume difference is there? Can you describe the sound a little? I'm interested in something a little throatier, but not overly loud. I'd love to still hear the radio on the interstate. Thanks.

 

My question would be how were the gains in the 1000 to 2000rpm range. Most of the time I'm not running at 4000+rpms on the trails or rocks.

The power increases are nice. But what's the noise penalty? In my experience, exhaust and intakes that make big hp also make big noise. What's the story?

 

Ditto this question. 30+ HP gain at 4000+RPM doesn't mean a whole lot on the trail unless you want to snap an axle or worse. I too would be interested to know what the gains were at the 1000-2000 range

 

this is GREAT data thanks.... would you have a price breakdown of these parts and overall feel for the power. Finally sound.... Thanks for taking the time to post these results! 230hp is how the truck should have come from the factory and I would be willing to get there but at how much and what else could be compromised? Thanks..... please post back!
