Utilizing the stock valve controls with a custom designed muffler to go from quite to extremely loud in less than a second.

Take into consideration that videos are quite misleading in representing sound volume.

Bam!

You sure hit him good.

The correct term you are looking for is Scavange.

And it doesn't nessesarily need it, but the more scavange there is, the more low end torque you make. The less scavanging there is, the more high end power you make. Too much is bad, and too little is bad as well. One of the best tuned headers will produce maximum scavenge when the intake manifold reaches 0 psi vacuum (ideally). That way you maximize peak torque and after that help high end horsepower.

I just hit you with some knowledge.

lol i know how cut outs work, i just forgot that modern fuel injection systems don't need back pressure...

[userchemical]

shows what you know about sbc. If you knew how a cut out worked you'd know they are installed closer to the headers to allow the exhaust gas out faster, thus allowing more air in. Having Headers increases your back pressure. all this person did was block off two exhaust tips...

NA cars actually need some back pressure

[userchemical]

i would have installed the cut outs just after the headers so it actually makes some performance...

I'm startin to get the feeling that you guys just chill all day?

[danhr03]

did you do this by using kook's new electric throttle body? If I remember correctly, you can program it to open at certain rpms...
