Hi Ale, thanks for initiating contact. Yes, it may indeed affect the noise of your car. This is designed to increase airflow to the engine, which can result in better throttle response and potentially some performance gains. While its primary purpose is to improve airflow and efficiency, it can also affect the sound of your vehicle. Many users report that installing a throttle body spacer can create a noticeable "whistling" or "hissing" sound, especially under acceleration. However, keep in mind that the sound might be more of a high-pitched whistle rather than a deeper exhaust tone.

Hello! This spacer should work with a stock intake without cutting, but I'm not sure how much extra room there is with your aftermarket tubing. Perhaps another customer with the same setup will offer their experience.
