You would spend a stupid amount of money and have an exhaust system that needed to be hacked up and rewelded. Then, it would sound different due to the acoustics of the system.

That just covers the exhaust plumbing. Your engine and cam timing events would have to be reworked to achieve something similar at idle. Since the HC alters it's cam timing it sounds a tiny bit different at higher RPM. You have to pick one or the other.


In short, do what you can with what you've got. It'll never sound like a current production car.
