How do Turndown Pipes Work?
Instead of blasting exhaust gases and noise straight into the air from the rear of your vehicle, a turndown pipe diverts the exhaust and noise towards the ground. This allows car and truck enthusiasts to run a less restrictive custom exhaust while noticeably reducing exhaust noise.Turndown pipes are designed to fit over your factory exhaust, which means the inner diameter of the pipe must match the outer diameter of your exhaust tubing. They are welded, bolted, or clamped to the end of the exhaust to complete the installation. Some enthusiasts choose to use clamps until they are able to have the install finished by a competent welder. Enthusiasts often purchase and install turndown pipes to give their exhausts a finished appearance.
