Same here.... My wife has a rule that the car must stay in normal mode until I am well down the road, and we live in the country. :(
You could just increase the octane and buy a tuner to clear the rear 02 codes when they pop up. Therefore, not modifying the factory tune..not saying this is a great idea, just saying......
Higher octane doesn't account for increased airflow/reduced back pressure.
That was done due to packaging challenges using a short tube design and to ensure they could pass emissions.
Ahh thanks, too bad it doesn't fit. Any ideas on why all the aftermarket offerings stray from the original design though? I'm curious now if the original design was purely to pass emissions and regulations, or whether the aftermarket manufacturers simply aren't as experienced when in comes to designing headers that aren't in the typical 4-1 long tube configuration.
Theoretically, a "bundle of snakes" on most V8's will give you the best overall average performance gains across the largest RPM bandwidth. This also includes taking firing order into account, overlap or not. Only zoomies would be able to best a 4 into 1.
So the 4-1 configuration is typically the most efficient at improving the power band is what you're saying?
Typically, yes.
I think that's just more video audio quality. SW does a FANTASTIC job at accurate sound comparisons. Sound wise, long tubes are long tubes are long tubes. What makes the biggest difference is going to be materials and build quality. Otherwise the sound is going to be pretty much the same when comparing long tubes to long tubes or short tubes to short tubes in the same collection configuration. There maybe a SLIGHT difference if say a set of headers you were comparing had a collector that was a complete dookie job but other than that, you won't hear a difference from one manufacturer to another.
Very well could be the audio for sure. I wasn't prepared for how loud the car is in person, videos simply can't capture the real sound or volume properly.
