I don't really understand why people want to put loud exhaust. There's an exact science of this and loudness doesn't always mean more power. Please learn the basic words like pulsing, scavenging, choke points, and back pressure. After than proceed to the advance level and learn how to calculate the best pipe diameter, pipe length, etc... basing from your cylinder bore size and stroke, compression ratio, etc , including additional mods like superchargers and what not. Tuning is not just adjusting an aftermarket ECU but tuning is also as simple as putting the right pipes..etc

When you apply the science of it, you are a tuner... otherwise, you're just a ricer.
