One of the best sounding engines for kit cars.

I see people with lamborghini and ferrari kit cars and most people use a V8 or a mr2 or fiero engine which none of them sound like a exotic car so thats a dead give away that the car is fake. The best sounding engine for them types of kit cars I found so far are Honda NSX engines. When you run them with no mufflers or resinators just using streight piping they sound just like a ferrari or lamborghini. And the best part is the engines go for around $4000 used.
