Before and After Header Sound Clip Help Please
I've searched on youtube and here with no luck. Does anyone have any sound clips to compare before and after a header install through the stock mufflers? I'm curious about the tone and sound level. Does the interior stay quiet? Is it just a beast at WOT? IME with my other cars they were considerably louder after LTs were added, but those were full exhausts (borla or flowmaster mufflers, nixing the cats and running all new pipe) on american V8s. What about shorties and keeping the cats? If no one has clips comments would be greatly appreciated.
TIA,
Sterling

No interior but a pretty cool before and after exteriors on the dyno.
Before
After
Skip to about half way in each vid as the build up takes forever.
I have had Kleemann headers with everything else stock and the interior was just fine. No drone and cabin was great. Just nice evil rumble.
Now that I am a full "tracks up and down the arm" mod junkie, I have long tubes, with X pipe straight out with race cats, no resonator and stock muffs (all pipes 3") and it officially is a tick much inside. At red lights are my favorite, it gets into a range that the drone just resonates all over the place. People are all looking over at it. Kinda fun.
My kids say it's pretty droney in the rear but it's not like you are shouting up front. Just when that low end "lugging" of the engine happens, it's a bit loud in there.
You'd love headers on this car. Sounds amazing!

Yeah, feel free to come and drive my car, smash the gas, windows up, down... Its beautiful. 
Our cars are heavily insulated. When the windows are up, not that much noise will be heard inside the cabin. I love it mostly when i'm driving in my parking garage.

The difference between these cars and other cars is the power adder (S/C) VS naturally aspirated.. Normal driving, you are driving a low compression motor around and the car is quiet, plus a ton of insulation..
AT WOT,, it is like being in an F1 car,,, so I presume!
All hell breaks loose! Pure race car and that is with race cats, stock resonators and stock mufflers. ..

Brooke, didn't think about the S/C vs NA difference.
Shardul, I do need to make it to a cars and coffee. I think I'll be in town for the next one. Haha, I think.
I need a free weekend to install the box of parts I have sitting in my bedroom for my girl.

And to be honest I think headers woke the girl up way way more than the pulley and tune
Do it, you won't regret it.
