Hi, So I bought a VR6 with the sound being a deciding factor. It has a Magnaflow exhaust and it doesn't have that sound that I have grown to love from almost any other vr6 that I've seen or driven. It lacks that low down rumbling noise you get as you accelerate hard from low rpm. Instead it has a hard to explain but a droning noise. I don't think anything is loose. Could this be a leak? It backfires at low speeds under hard acceleration. My impression is that this is the sound this exhaust makes. If I change the back box will it give me that beautiful VR6 racket
