Frequently Asked Questions
What size exhaust for deleted diesel?
4" is minimum for deleted diesels; 5" is ideal for heavily modified trucks. Larger diameter dramatically reduces EGT and backpressure, crucial when deleting emissions equipment. Straight-pipe or single muffler designs flow best. Note: Emissions deletion is illegal for street use.
Will bigger exhaust help my stock diesel?
Yes! Even stock diesels benefit from 4" turbo-back systems. Expect lower EGT (50-100°F drop), slightly better MPG (1-2), and improved throttle response. Gains increase dramatically with tuning. Larger exhaust is essential foundation for any diesel performance build.
Turbo-back vs DPF-back exhaust for diesel?
Turbo-back systems (from turbo to tip) provide maximum performance by reducing all backpressure. DPF-back systems (behind diesel particulate filter) maintain emissions compliance while improving flow. For stock trucks staying emissions-legal, DPF-back offers best balance of performance and legality.
How much HP does exhaust add to diesel?
On stock diesel engines, exhaust alone adds 10-20 HP. With tuning, the same exhaust supports 50-100+ HP gains by reducing EGT and backpressure. Exhaust is essential before adding power - it's not the biggest power adder itself but enables other modifications to work safely.
