3 inch downpipes are even better, but they are more expensive, and require more installation labor, and the open dumps are LOUD.

hence why you would want a tune lol.

This would be the main reason you would want a tune. You would make more power by leaning out your tune however you are running the risk of detonation.

if my car is running pretty rich, adding the test pipes would lean out my tune a bit right? so would it be safe to run the test pipes without a tune since it will lean out my tune?

open dump question means.. wastegate opens into the atmosphere not back into the exhast???

What if you take off your test pipes? Do you need a tune?

So in this case, a retune is not required from a safety standpoint, but recommended, in terms of maximizing your power.

That's why you route the back into the 3" exhaust at a smooth angle down the line.

That's the best of both worlds right there.
