Got the car back yesterday and i'll post up some videos later today or tomorrow. I tried taking some videos yesterday, but it was pretty windy and you can hear it so i'll have to take new ones.
Dynos are extremely confusing to me and i've got an email out to Paul to see if he can provide some information. I have the base line dynos then dynos for after headers/exhaust. It only gained 34-37whp from both headers and exhaust so i'm not sure how that could be. Temperature was the same in both dynos at a cool 103 degrees.
Looking at Lou's prior dynos it looks like he gained about 18whp from the exhaust alone. Equal length headers appear to be gaining about same as unequal length at peak from his unequal/equal length dynos.
I'll post up the dynos later as well with the sound clips.
EDIT: I just noticed the temperatures when Lou ran his Dynos which were 70-80 degrees.

I'll have to buy one of the cables then get tech stream as I don't have either at the moment. The car only has 23k miles so I can't imagine the plugs are all that bad, but other than the throttle body (I guess KCLV could be an issue) or plugs I can't think of why the numbers are so low.

Oh snap didn't know that he was running the Novel tune?
Yea like redcrxsi said above you need to check your KCLV numbers to see where they are below 3k & above 3k and see if the computer is trying to advance timing when you are WOT
Edit: Never mind on the tune saw your response above

Yea Lou's run with his unequal length headers and exhaust made around 390ish but like you said the temps were about 20-30 degrees cooler....... so? You might not get accurate or close to par numbers until you dyno in like conditions?

I don't have any tune at the moment. Waiting for a custom tune option in the future.

With the stock tune, I'd be very surprised if the KCLV values were off

So here are a few clips I took tonight while driving. I can try to do some WOT videos later, but it gives you an idea of how it sounds. Idling is with closed valves at first then I open them. Rest of the clips are opened valves.
