Okay, but all of Borla branded systems for the 2018+ are 3" systems except the Touring.Bigger is not better, exhaust is all about velocity to pull spent gases from the cylinder during the exhaust stroke a larger pipe slows down the velocity and will rob you of power. Borla knows this, that is why they have more wins in professional racing than all the other exhaust manufactures combined.
