Glad to help. The sound in the video vs. real life I think is pretty close. It's hard to be sure because the sound in the cab is different than what you hear outside. I will say that the initial startup/rev is a bit more raspy than how it actually sounds, at least now. The bark it makes on a cold startup (especially in cooler temps) is aggressive though. It was around $550 from Summit for the single outlet, I didn't want duals, it just seems like everyone has them. Also, out the back duals will echo like a bastard if you tow an enclosed trailer/camper. I went dB/Corsa over the rest because the drone/resonance is minimal with the dB kit. When you're driving down the highway it is a nice quiet rumble compared to the boomy-ness of exhausts I've heard on trucks with Flowmaster or Magnaflow setups but then when you punch the gas, the truck will clear it's throat and make some noise. As for sound, I think a bigger tip might make more noise but personally I think a 5"-6" tip would look a bit absurd. Again, that's all personal taste though.
I've never been crazy about the rolled tip design and the single inlet/dual outlet tip that comes on the Corsa system for my truck is ugly to me. Plus the Corsa is almost twice as much.
