Thank you for taking the time to read my question. I just recently just purchased a 2010 WRX in which I just extended the warranty. I am looking into an intake but I am aware it does require a tune. I would like to make the sound of the turbo more prominent. I don't want to tune my car because there is a possibility that it may void certain repairs. I know I can unmarry it with the cobb access port but I cannot afford any chances. Are there any other alternatives? I am not looking for any gains. I just love that sound. If I just change the filter alone to a k&n cone filter will that cause any problems and is that possible? Would it make the sound more prominent?
