Okay, I have to call B.S.

I am disappointed, I was looking forward to what we can expect from some exhaust changes. You didn't even get headers.

The chart you posted shows a gain of 37 RWHP and 50 RWTQ.....
1. You would remember gaining 37hp & 50tq at the rear wheels. That is more like 45 crank HP gain and 60 crank 'torque...
2. You mention good strong pulls in the low-end torque bands, but the graph doesn't even show below 3500 RPM. At that point, the two lines are meeting anyways, which is the least difference.....and it is what you happened to mention as being where there are good strong pulls.

 

I had the same feelings king.

Having watched a "name brand" muffler system sell a Charger a costly setup "On-Site" in Carlisle at the All-Chrysler Nationals, only to see the guy get a dyno pull BEFORE the install and again AFTER the install to see no-gain... it was eye opening. It did sound better however!

With that said, the HEMI is exhaust manifold restricted. I agree headers (when available) will be the ticket. I don't see such a dramatic increase in HP/TQ from ANY exhaust only modification. If that was the case, it would ship that way from the factory.

20-ish as he mentioned before the chart was surprising but believeable **if** I guess at the top end. These chart numbers just seem out of whack.

Perhaps it isn't the OPs fault, perhaps the dyno wasn't ran properly **or** if they were involved of the sale of the exhaust, then there is a conflict of interest there somewhere.

Oh well, the new setup sounds good... if not a tad to loud!

Ok guys...a couple things - first, I apologize for the lack on information in the picture upload (I tried to upload the damn thing 5 times and it kept saying a was over the size quota limit - I had a long email accompanying the chart). So this dyno chart includes CAI and high-flow cats (my most recent mods). Believe what you want - if you lived in Miami I'd take you to the shop to see the run for yourself. I wouldn't make this stuff up, no reason to! We're all working together here to simply have fun with our rides and share information. For the record, the dyno and muffler shop are totally unrelated.

 

What CAI do you have? If you want to email me the full dyno I can host it on my website and then link it if you want. Personally I wish I had a way to setup something similar (probably something just a tad bit quieter for my tastes but that could all just be how it came out on the camera.

 

I have the Volant CAI. The exhaust is def not as loud in person as it is in that recording. I still want to do an outdoor (not in the garage) shot along with a drive by. I have a magnflow cat back system on my 2010 Ram Hemi - the Durango system sounds similar at idle.

 

How did you get your hands on that intake so quickly? It looks like it was released 2 days ago lol Any thoughts on the intake?

 

I had pre-ordered it - pros: fits very nicely, has good flow, the box/heat shield effectively keep cooler air. I've gone with Volant on other cars and always liked them (tend to be a little cheaper than K&N and you can choose an oil-free filter if you want). The K&N for the Ram sits a lot closer to the passenger manifold...that's why I went with Volant on my truck. Alone I'm not sure the CAI would make a difference. With the exhaust mod on the Durango, it does appear to have helped the engine run a little more smoothly. I'm also planning on tuning the engine once a tune comes out and the CAI does help a little bit there.

It does look cool though! The Volant website has a pic:
