Unfortunately none of the rear sections are going to give you a high pitched sound. Just is not possible. The ONLY way to get a higher pitched race sound is going high flow cats or catless which is what I did with AA xpipe plus HFC. Stock rear section. Gives 0 drone (not just saying this like others say gintani has low drone). Truly none.
If you want to know how it sounds, go to youtube and look for bmw m3 dtm race car. It has the high pitched raspy sound. Kind of like the e46 CSL sound but much better.
Rear section alone simply wont give you what you want
