The Wehrli 3" passenger-side upper crossover intercooler pipe for 2011–2016 Duramax LML increases size over the OEM part to reduce restriction and improve turbo spool and efficiency. It removes the resonator for a cleaner appearance and more aggressive sound, connects to the factory throttle valve and grid heater, and fits stock trucks without modification. Finished in custom powder coat and supplied with a billet turbo resonator plate where required for a bolt-on upgrade.
