I'm looking to get a high rev screaming sound on my sedan. I plan on having berk resonated test pipes, megan racing y-pipe, and likely some form of a resonator delete with an axle back (like hks hi-power). The link of the type of sound I want is below, yet it was achieved with a resonated delete on a top speed pro-1 y back. From a lot of the videos I've watched, many people don't get that screaming, high pitched sound at red line with a resonator delete. Is this because you need a larger mid pipe when doing a resonator delete? Does the stock mid pipe diameter not allow for the sound I'm looking for? Thanks. I've also included someone's instagram who has a gthaus mid pipe (also resonator delete) and the screaming high rev sound.

that "high pitched scream" you're hearing is rasp. I can assure you from personal experience, it does not sound as pleasant as it does on the videos. Rasp is what shreds your ears and can cause your car to sound like you pieced together an exhaust from autozone. ARK and Motordyne catbacks will give you a bit more of that scream without the rasp that a resonator delete will cause. You're free to do what you like, but these cars NEED resonators IMO.
