Downpipes

Performance downpipe with a HIGH FLOW Catalytic Converter from MILLTEK.

200 CPSI high performance catalytic converter and a large bore mandrel bent downpipe with 2.50 inch (63.50mm) pipe diameter produced in high quality 304 aircraft grade stainless steel. This pipe flows up to 90% of the engine exhaust compared to a decreased range of 50%-65% or less airflow through a restricted stock catalytic converter. The reduced back pressure is just enough to maintain good low-end torque. In addition the reduced pumping work on the engine will increase MPG and pay for the cost of the pipe over time.
