K-Tuned 3 Inch Downpipe Released for 9th Gens!
Posted by on
K-Tuned has a new treat for 9th gen owners with the release of their 3 Inch Downpipe for the 2012+ Honda Civic Si. Available with or without 200 cell steel core high-flow Cat. Also optional and highly recommended is the Hasport Rear Engine Mount which can be purchased separately or in the pulldown menu.
The 2012 and up chassis now comes with a bigger K24Z engine and a brand new cylinder head design. Looking a bit more closely at the exhaust side, you'll notice that the exhaust ports all merge together into a single outlet flange that is cast directly into the head itself. Bolted up to this flange you'll find the stock catalytic converter positioned right before the exhaust piping. It is pretty much common knowledge that stock catalytic converters can be very restrictive and when they are deleted or replaced with high flow units, the result is noticeable increases in performance.
The K-Tuned 9th Gen Downpipe completely replaces the factory cat section with a free flowing 3" downpipe. The T304 stainless 3" diameter pipe section is beautifully tig welded and bolts up to the housing, before heading downward perfectly past the factory subframe and swaybar. Welded into the lower part of the downpipe is a high quality Vibrant Turbo Flex section with interlocking inner liner to absorb the normal engine movement along with 2 O2 sensor bungs on the cast housing.
