Honestly, I'd rather it be quiet if I had the choice.
If an exhaust would make the same or better power and cut down noise that's what I'd be running instead of the Cobra.
I prefer my fuel to make power as opposed to noise, but if a noisy exhaust is the only way to make power then that's what I use.


Kinda like glass packs on an old truck...there's other mufflers out there that do a much better job scavenging and creating power and are a lot quieter to boot, but everyone thinks glass packs sound soooo cool
