K-Tuned 3" All-Motor Downpipe
The K24Z engine comes w/ a new style cylinder head design. The exhaust ports all merge together into a single outlet flange that is cast directly into the head itself.
The K-Tuned 9th Gen Downpipe completely replaces the factory cat section with a free flowing 3" downpipe. We started things off with a cast stainless steel housing, designed to offer a smooth transition from the head flange to the exiting 2-bolt exhaust flange. The T304 stainless 3" diameter pipe section is beautifully tig welded and bolts up to the housing, . Welded into the lower part of the downpipe is a high quality Vibrant Turbo Flex pipe. On the cast housing, we positioned 2 x O2 sensor bungs, one for the primary O2 and a second for a wideband O2 sensor. . We include all the hardware needed for installation, including: 1 x O2 plug, 2 x serrated M8 nuts, 1 x M8 bolt and 1 x M8 washer for the housing to head connection.
