I had no idea how complicated the physics of simply getting the exhaust out of an engine were. So basically, some shade tree mechanic tinkering with his exhaust system has a 99% chance of making it worse. Especially if that car is designed with performance in mind. Such as an exhaust system that is completely encased in insulation with a heat shield on top of that.
No wonder exhaust system mods are so hotly debated. Sounds as complicated as nuclear science, yet any joe blow can claim to know something about it.
