Yes this product will make your engine bay hiss at idle but who cares we are after the performance. Yes, this product amplifies the raspy sound as your car drives through different RPM ranges, but who cares, it has improved performance. And yes, this product will increase your overall productivity. The only problem is that now I drive my truck like a race car because I like the noise it makes in low gears at high revs. vrrrrrrmmmmmmmmmm
