Upgrade your diesel performance with an MBRP Turbo Downpipe. The turbo down pipe is an often overlooked stock component that can really restrict exhaust flow. When you’re looking to upgrade your exhaust system, and even if you’ve already installed a down pipe-back performance exhaust, consider upgrading your down pipe for better diesel performance. More exhaust flow means better performance, and MBRP down pipes are constructed from mandrel bent steel, removing restrictions and improving exhaust flow. Your turbo will spool up faster, giving you noticeably better throttle response.
