my old car that i use to have and did up with an exhaust system i didnt have the new extractors that i put on and cat, but it sure did sound like an 8 even a guy thought that it sounded like an hour then i put extractors and cat on it sure did sound like an 8 especially at idle, but since now i got a commodore gen3 5.7 just need to put a 2.5inch on the back and that surely will turn into an 8 sounding machine. last car i had and still got was a 95 ford fairmont ghia straight 6 with the ticky motor in it. just bought a vx berlina series 2 5.7L which last weekend i found out it has the hsv full exhaust system on it but that will be all going
