Dear experts,
If I have a 350 engine on my 1946 chevy truck and want true dual exhausts on it do I have to modify the engine. I had the pipes done on my 2001 truck, and they told me they did not reccomend true dual exhausts without engine modification, so reccomended is one manifold pipe connected to two pipes coming out the back for good sound and an increase in power of a small percentage. What say you?
