Commonly Stocked Item - Please contact us to confirm stock
TEGIWA – Honda Civic EP3 Cat Downpipe 70mm 400 Cell [MOT Emissions Compliant] ( Type-R 2001-2006 )
Our downpipe replaces the restrictive factory unit that comes fitted to the EP3 Type R. This optimises exhaust gases leaving the engine, as well as recuperating a few extra HP thanks to the 400 cel catalytic converter. The internal diameter is made to match that of our cat back exhaust system perfectly, 70mm OD, 66mm ID.
This product comes complete with gaskets and fitting kit. As you can see from the graphs the MOT emissions test reads below half of the limit, making this downpipe compatible with MOT’s here in the UK. The dyno graph shows an EP3 fitted with our 400 cel downpipe as well as our airbox and cat-back exhaust system.
If using a stock ECU this downpipe will bring on the EML. This can be removed by tricking the ECU with an angled o2 sensor spacer – ATEXHFO4
