Milltek Large Bore Downpipe with Hi-Flow Sports Catalytic Converter | SSXM015

Performance downpipe with a high flow, high performance catalytic converter from MILLTEK. 

Large Bore Downpipe with 2.50 inch (63.50mm) pipe diameter produced in high quality 304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers stainless steel may not be) and is less susceptible to discoloration. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid range torque. Includes bungs for the O2 sensors.

The catalytic converter features a 200 CPSI (cells per square inch) core housed in a fabricated stainless steel shell.

BENEFITS:

• Provide power gains up to 30HP, with the addition of performance air filter and cat-back performance exhaust, depending on Catalyst model and Vehicle.  Additionally, power gains up to 68BHP have been achieved in the UK with ECU engine reprogramming, depending on the catalyst model and vehicle.
• Will give you 90% airflow, compared to a decreased range of 50%-65% or less airflow through your restricted stock catalytic converters and other aftermarket catalytic converters, with 90% airflow being the highest airflow available in a catalyst that is street legal.  This Milltek pipe will also give just enough backpressure to maintain low-end torque.
• Will provide a reduction of up to 60% less backpressure, compared to other catalytic converters.  No matter what modifications you do to your vehicle, stock catalytic converters will always restrict the air flow and decrease the HP.
• Increases MPG has been achived in may applications.
