Here is a short video driving through the Malibu tunnels with my Dundon headers now on the car. I have the exhaust valves open and made a few high RPM pulls : ) When the exhaust valves are closed and under 3500 RPM's, it sounds as loud as the stock manifolds.

Just installed Dundon Race Headers with stock PSE.
Came from FVD sport headers with Cobb Stage 1 tune.
First impressions, def a bit louder and sounds great at wot. Not feeling any significant power improvement. What could I expect with a better exhaust and the Dundon tune? Appreciate any feedback. TIA.

Here is my Dundon story. I have redynoed and my peak WHP was 385 so only 5 from the intake runners. So I got a peak of c40 whp per them from the mods.
The guy who did the fitting and tuning says 395 WHP but all readings are very intake temperature dependent.
So getting a Pro Tune tune is definitlely worth doing.
Intake runners (this is true on Dundon or GT4 Clubsport intake) moves the peak higher up the rpm range. There has been much debate on whether these intake mods are needed....I am pleased with mine.
Hope this helps.
