4" stainless mandrel-bent system. Dramatically improves flow; virtually no backpressure; lowers EGTs; safely clears spare tire; throaty sound; huge polished ob-round tips.
This is a Cat back exhaust system.
Monster Diesel Duals 4" exhaust system flows up to 88% better than stock and virtually eliminates backpressure. The streamlined 4" turbine outlet pipe (not required with 325 hp systems), intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps. The dual tailpipes have 52% more flow area than a single 4" tailpipe.
