glad you could make it scree. Look forward to seeing you again with your stook!

 

Here are a couple more pics of the cars being Dyno'd. Plus a couple of screen shots of the results.

This was a great chance not only to see the preformance difference, but to hear the sound difference of these exhausts. Because, it seems that the greatest difference among these exhausts is not performance but its in the way they sound.

 

Did anyone record the sounds?

 

No, we all had a brain fart and didn't think of it until we heard the Comptech with the airbox cover off, our last run of the day.

We were all saying "Hell Yeah!" and then it dawned on us, we should of recorded it. Oh well, we'll do it again in the future and we can record it then. However; I think being in the walled service bay added to the effect. It would be hard to reproduce in a low quality recording.

 

To hold our curiosity, maybe someone could just rev the engine up to about 5K next to a mike. It would give us an idea.

 

I would recomend an audio recording of a Dyno run. To hear the tone of an exhaust at just one RPM just doesn't do it justice. In fact when we did the dyno runs on monday the thing that impressed me the most was hearing the car pull in 3rd gear from very low RPM upto ~9K RPM. It makes the hair on the back of your neck stand up straight to hear the engine wind up like that. When you think it can't possibly go any futher, it just keeps on going.

Another point of this is that in the ramp up in RPM you can really notice a couple of resonence point with the CompTech Exhaust, whereas the HKS and Stock exhaust were smooth in tone all the way through the pull.
