Frequently Asked Questions
What diameter exhaust does my diesel truck need?
Stock diesel truck exhausts are typically 3.5" to 4" diameter. For most street and mild performance use, a 4" turbo-back system is the correct upgrade — it provides meaningful improvement over the stock exhaust without oversizing for the flow requirements. For high-power builds with compound turbos or significant injector upgrades, 5" exhaust becomes appropriate. Diamond Eye offers both 4" and 5" systems for most diesel platforms.
Does a larger exhaust alone improve diesel power?
On a stock diesel truck, the exhaust is rarely the primary restriction — EGR systems, stock injection parameters, and turbo sizing limit power more significantly than exhaust diameter. A performance exhaust is most beneficial when combined with a tune and other supporting modifications. It can improve EGT (exhaust gas temperature) management, which matters more for towing and repeated performance use.
