Does this add noticable turbo whistle? Is there a drastic increase in cab noise?

No increase in cab noise but anytime you increase airflow either into or in this case out of the motor it will increase whistle noise. On my 2000 with just this system and no other mods whistle was more noticeable but not extreme. However this system really works best with a good quality intake to feed the turbo and at that point, there is quite a bit of whistle. hope that helped

On my resonator-less 2005 Subaru legacy gt wagon it makes a muffled dumping sound which is more pronounced than stock. Most of the time I don't really notice it. If you have an aftermarket intake you will notice it more than if you have the stock intake with all the resonator pieces in place.

I don't hear a dfferencein normal driving, just the "roar"when stepping on the gas. Haven't noticed any whistle.....

No, it has a "turbo" setting but it doesn't increase the volume of air. Actually, the volume and pressure of air flow is so low it is all but useless. I would have returned the device except in the small print it says an opened box can't be returned and an unopened box has a 20% restocking fee plus shipping both ways. Amazon wasn't any help on the deceptive advertisement and calls and emails to the company went unanswered. The unit is all but worthless in my opinion and the company is a scam.

Not a lot but it does boost noise you may already have from pickups or whatever.

I purchased this device once before in hopes of adding torque. It doesn't add torque or even increase the mpg on your vehicle. It does however, make a cool noise when you step on the gas. But there is also an annoying whistle sound when you're just driving around. So again, no actual benefits except for "performance sounds". I hope this response provides clarity in your decision.

About 8 - 10 hp....but it does add a good sound..Your car sounds like you have added a new exhaust.

Our ballast does gives off humming sounds. But on the older ballast gives off buzzing sounds. So to answer your questions, yes, it is very annoying.....

I have it on my 5.7 liter and the cab noise isnt terrible definitly on the quieter side

Well for me it toned down the higher pitch portion of the sound, leaving the moaner, droanier sounds behind. I had it on a SLK with a Eisenmann tuned exhaust. I returned mine if that makes any difference.

I have this muffler on a 2014 5.3L vortec crew cab with pipes coming out in front of the axle on the right side but I also have sound mat all throughout my truck so I don't get any of that annoying drone sound or even road noise, however I did have this same muffler on another 5.3L vortec lowered extended cab with turn downs underneath it and no sound mat and there really wasn't any of that reverberating sound like any of the other big exhaust companies mufflers and I've had them all. Borla really makes a different kind of exhaust note, that's why I keep going back to them.

None at all, nice performance enhancement...no audible sound increase and horsepower gain noted.

Makes a higher pitched noise than stock, but not much louder if at all. I can say that performance is perfect...Stock BOV was leaking at 18psi, this one was boost leak tested to 22 psi and did not leak at all. Hope this helps.

You get a better throttle response. Also it sounds much better, especially if you upgrade your exhaust.

yes, it gets really loud, even in my postal vehicle. Sounds a bit tinny to me, but I think I can modify that according to the instructions.

When you initially step on the pedal you will hear the intake sucking in air. The tone of your exhuast will be much deeper under all driving conditions, much like putting a four barrel carb on an old carbureted vehichle.

No catch it's the full exhaust system. I have had mine for over a week now sounds like a beast.
