These downpipes are a full 3" downpipe and are manufactured out of 304 stainless steel with brushed finish. Each pipe includes 2 X O2 sensor bungs so you can transfer your oxygen sensors over to our downpipes allowing the ECU to continue to operate as normal. You have removed the cats so you will need to reprogram the ECU or get a CEL fix to avoid a CEL light on your instrument panel.
We have found a superior pipe bender with a higher tech bender who can bend these pipes without cutting and welding. This superior fabrication technique creates a smoother interior pipe ensuring better air flow.
This straight-through tubing section replaces the heavy and restrictive OEM catalytic converters for maximum power and sound; recommended for track/off-road use only. For left hand drive models only!Features:
- Straight-through design allows for maximum power and sound. Less back pressure improves turbo response and improves horsepower and torque significantly. Typical gains are 20-25 HP
- Direct bolt-on replacement for OEM primary catalytic converters
- Less thermal load on the turbocharger
Reduces turbo lag
- Our downpipes come complete with gaskets and bolts
