Great Product
jacob | November 30th, 2014
Easy to install! Perfect for race headers! Thanks K-Series parts... Installed on ep3
Kevin R. | February 27th, 2014
The perfect fix for running anything other than stock exhaust. Use this on an EP3 when installing RSX-spec exhaust or turbo downpipes that don't have the O2 bung in an ideal location. Kseriesparts delivers another great product as always.
Necessary part

If you are planning to do exhaust work or install headers, do yourself a favor. Get the extension to make your job essier and complete. As others said. Perfect fit and a prrfect length.
